Outlook calendar sync problem

I have a BB8310 that has given me great service for over a year.  Two days ago the calender stopped synchronizing  with the Outlook calendar.  When syncing the device, the address list, task list, memo pad all sync perfectly.  The calendar does not sync at all.  Any suggestions?

Hi,
I sure hope you can come back, you don't have to lose Facebook.
You obviously must have an email associated calendar on the device, which I was trying to establish.
You can set the Facebook calendar to update your email associated calendar and sync all events.
I will send you a PM as well.
Thanks,

  • Major problems with iPhone 4 & iPad 2 both 5.1.1. - Outlook Calendar sync

    Folks, really need some help here, being forced to revert to Blackberry Bold 9000 because of issues with Outlook Calendar sync since 5.1.1 upgrade on both my iPhone & iPad.  Our company Enterprise Active Sync server is 2003 (please don't mention upgrade - already a seperate conversation byt all costs).
    email sync's fine on both devices, plus i can continue to use both iCloud accounts, and BT yahoo mail etc !
    national holidays set up in Outlook calendar come across, as does some calendar items, but then falls into a resync mode with nothing staying in the device, i can also see and read calendar invites, but once accepted, they disappear !
    Searching the internet suggests I'm not alone with this issue - any ideas welcome, seems not to be a problem on os 4 !!!  but A) I don't know how to regress and B) why should I ?
    Many thanks in advance, please don't make me go back to a BB !!!
    Finally, I've been using the devices without issue for nearly 2 years - so again it's linked to 5.1.1. upgrade !

    Hi Tim
    Firstly, apologies for the slow response to your very quick reply !
    I've checked back, we're using Exchange 2007.
    We've actually got a ticket open with Apple at present, so anticipate that a patch may be available.
    It is still curious though that out of a 200 user community trialling our internal iPhone & iPad pilot, we only have 2 issues (mine and a colleagues), however anticipate that there will be more issues as nearly entire community is on 5.1.1.
    On a second point, any ideas how one can rollback to 4.3.3 on an iPhone or iPad ?  I can't find anything that implies a self rollback without jail breaking the device ?
    Thanks again for the help.

  • Problems with Outlook Calendar syncing with my Palm TX

    I have recently started have problems getting my Palm TX to sync with Outlook 2003 Calendar. I don't have any issues with Contacts or Tasks syncing. In the Hot Sync log, I get the following error code "OLERR:03-0024 (0x8000ffff)". Any ideas what causing this?
    Post relates to: Treo 700p (Sprint)
    Post relates to: Treo 700p (Sprint)

    Relates to Palm TX but probably applies to other Palm's.
    I had same Calendar sync problem but with Outlook 2007 (Win XP). One day I could sync, next I could not.  I tried resets, re-installing software, running DbFixIt but nothing worked. I kept getting a log saying "Sync with Calendar had failed."
    The solution turned out to be more simple than I imagined.  Just make sure you have the Microsoft 2007 patch installed if you are running Office 2007.
    Here goes...
    Right click on the sync symbol on your PC. Left click on "Custom" from the drop-down menu.
    Under the Custom menu, select Calendar (Outlook). On the right side click "Change".
    Make sure the button is checked for "Syncronize the files".
    Next click on Settings. Decide what you prefer, e.g Handheld wins" in the drop-down menu.
    You might also decide you want to sync two computers (e.g. a desktop and a laptop). You will see an option to apply that setting on the same Setting menu.
    Click OK. Then you MUST make sure the "Set As Default" box is checked for this to take effect in future.
    Finally click "OK".
    If you are having the same problem with Contacts, it is the same procedure except you pick Contacts (Outlook) in the Custom menu.
    It fixed my Calendar sync problem and everything is back to normal.

  • Outlook Calendar Sync Frustration

    Ok....I've done it all. I've reinstalled....numerous times...earlier iTunes versions...operating systems...reduced my pst files to less than five appointments, none of which are recurring...rebuilt pst files....you name it, I've done it. My Outlook calendar still does not sync with iPhone/iTunes. I get the "outlooksyncclient.exe" has encountered a problem and needs to close..." error message. I'm inclined to subscribe to the point of view I saw from one poster that PocketMirror/Palm figured it out, Apple should be able to as well.
    What really appears to be happening is that one of the two add-ins that iTunes/iPhone requires isn't being loaded. According to Apple documentation, you need "iTunes Outlook" and "Outlook iTunes Sync" add-ins. I only get the iTunes Outlook" add-in from iTunes, no matter what version I install, reinstall, deinstall, reinstall, etc. One would think that if "syncing" is the problem, you'd want to get that second "Outlook iTunes Sync" add-in loaded and seen by the OS, no?
    Even when I was with a VERY good tech at the local Apple store, he didn't want to touch the issue that the add-in wasn't being loaded. To be fair, he saw it on the computer (haven't been able to locate it myself, but I saw it when he ran a registry list), but somehow it's either not being activated OR seen by iTunes. Seems to be a key player here, but the tech could only report the issue to tech support...leaving me in the dark since there is no way to follow up on the progress of the report to tech support.
    Am I alone here? For a smart phone/PDA, not syncing with what is probably the most used corporate contact management software's calendar is, well, not very smart (especially right out of the gate on this cutting edge tool).
    I'm not complaining about the phone features. It's LEAGUES above any phone I've seen. Having an iPod on board is just bonus. The Map widget is great too, especially linked in with the contacts (...which, by the way, seems to sync fine with Outlook...). But come on...if you can pull all that off, what's up with not being able to do the calendar? Want to lose the majority of sales folks out there that could truly benefit from this product? No sweat, just don't put a priority on fixing this Outlook calendar sync issue.
    I'm posting this because I have a feeling that if I don't, and no one else voices this opinion, it won't be addressed....and this would be a shame since this product has so much immense potential.

    Try this. Forgive me as I am not at my work computer but expericenced exactly the same problems.
    Go to edit your email account and assuming you are using outlook 2003 since I don't 2007 you will need to find the dialog box that says something to the effect of send your information to your personal documents. It is a drop down menu within settings. You will then need to close outlook and open it again. Try syncing your iphone and this worked like a charm for me.
    To sum it up your mail,contacts, and calendar entries are curetnly being stored on your work server. Iphone doesn't like that. When you tell outlook to store these items on your personal documents they then are stored on your hard drive and Iphone loves that. When I first tried doing this I noticed that I didn't have the option to send these items to my persnal files so if that is the case for you you will need to create it by clicking add and just pointing to personal files.
    I hope this helps.

  • Outlook Calendar Sync has stopped working

    Prior to iTunes 7.4.X, Outlook Calendar Sync was working OK.
    Now, it does not. No new calendar entries posted in Outlook following the installation of iTunes 7.4.X make it into the iPhone.
    I've tried all the usual tricks - reinstall iTunes, reset the iPhone, nothing helps.
    Any ideas out there?

    hi, thanks, i tried that as described here in the troubleshooting faq - no improvement.
    http://docs.info.apple.com/article.html?artnum=305845
    here's what i noticed however, there's not a second add-in as described in the doc. the Outlook iTunes Sync add-in is missing on the system entirely. after re-installing, iTunes, it's still not there and so can't be added through browsing to the iTunes dir and therefore i can't select it.
    where can you get this second add-in? also following these instructions, i deselected the microsoft outlook mobile service add-in which sounds like it might be needed. ??
    thanks for any help.

  • Outlook 2003 + iPhone calendar sync problem solved

    Here is how I solved my sync problem. Seems a lot of people have the same problem here with Outlook sync suddenly not working after it worked fine for a long time.
    I've had Outlook 2003 calendar sync with my iPhone for a few month without any problem, but a few days ago the sync suddenly stopped without any error message. iTunes Diagnostic found no problem and I followed all the steps that Apple outlines to fix the problem but nothing worked (TS2776).
    As Apple asked to, I created a new user account on my Windows machine and setup a few test calendar entries to sync with my iPhone. That all worked fine.
    So I did what Apple doesn't tell you, and I copied my original Outlook Data file (.PST) over to my new user account and tried to sync that one. Now this didn't work. So I knew the problem lies somewhere in my PST file.
    I have then tried to create a new one from scratch in my original Windows account, and copy all the data over. Again, it didn't work. So I emptied the file again, and copied all my calendar entries over to the new PST file in batches (first 10, then another 10, etc).
    What I found at the end is that one single calendar entry I created a few days ago caused my sync to stop working. Once I removed this entry, everything worked fine again. Don't ask me what was wrong with it (I made a backup just in case Apple wants to see it), but now everything works again.
    If you want to save some time to find which one it is, you may start deleting entries that you created just recently before it stopped working.
    Hope that helps.

    Hi im having the same problem. I use outlook 2003 on windows xp and until recently my sync (using usb) was working fine. Now it would seem that calendar items are no longer syncing. can you give any further details of the calendar entry which was causing your problem? im wondering if it was added on a certain date perhaps.
    I am running the inbox repair tool to see if my pst file has any problems but would appreciate any other help in the mean time.
    Cheers

  • Calendar syncing problems with outlook and iphone

    Months and months ago I had the following window pop up when I go to sync my phone:
    "synching with iphone will change more than XX% of your calendars"
    First I have to say the vagueness of Apples messages is disappointing.  This message does not convey to me exactly what its going to do if I accept the message.  This is my first apple product and I love my iphone, but itunes and everything related to the PC is disappointing!  Anyway, I have been hitting cancel because when I attempt to lookup the problem online in a Google search I don't find any quick definitive answers.  I no longer use outlook on this computer, so I want all the calendar entries in the phone to remain the same.  I've attempted to uncheck calendar syncing and get the following message:
    "Itunes will no longer sync calendars to the Iphone.  Would you like itunes to remove calendars previously synced to you iphone"
    Once again, the infamous apple user friendliness I've heard so much about doesn't seam to be true!  This message is so vague.  What calendars is it going to remove, the ones on the pc or the phone?  And why would it remove anything, I just want it to stop syncing.  Urg, frustraded.  Any help is appreciated!  Thanks.

    Originally all of Apple products were intended for use with Mac computers. Macs have default program - iCal to sync calendars. Windows default program is ironically Microsoft Outlook. There couple more options in iTunes for
    calendar sync, but those need to be chosen and not default.
    In your particular situation since you don't have outlook anymore, you don't need to make any changes. No outlook - no sync. Apple way - no user interference nessesary.
    Please do remember that everyting I write is just my opinion, nothing more or less.

  • Calendar Sync Problem: Cannot write to outlook calendar using DM

    All syncing works fine between my DM version 6.0.1.18 and my Blackberry Bold 9700, EXCEPT that I cannot sync entries FROM my device calendar to Outlook 2007... The other way works. BB software is version 5.0.0.593 and it is BIS not BES.
    I have tried renaming/deleting Intellisync folder; the configuration on the DM is set to TWO-WAY. I have also reset the configuration on the DM. Every time I want to sync a new calendar entry on my Device, the message box says that it's reading the device entries and then processing them - no problem. Then it starts reading my Outlook entries, no problem. Then it processes Device entries again and highlights entries that need conflict resolution. After inputing required conflict treatment, I get the Confirm Calendar Edits window. So far great! I press Accept, and then get the Processing Device Calendar again...after it gets to the end, a new window appears and when it gets to record X I get the dreaded popup message "Operation terminated unexpectedly" error. If I delete the offending entry on my BB Device, the error disappears. However, until this problem is solved, I effectively only have one way calendar syncing: From Outlook to Device.
    Can somebody please help??
    Thanks.

    Hello flittda,
    Does the error occur when you synchronize your Contacts or just the Calendar?
    Delete the Intellisync folder from your computer:
    If you
    are using Microsoft Windows® XP, go to C:\Documents and Settings\<User
    Folder>\Application Data\Research In
    Motion\BlackBerry\Intellisync.
     If you
    are using Microsoft Windows Vista™, go to C:\Users\<User
    Name>\AppData\Roaming\Research In Motion\BlackBerry\Intellisync.
    If you still get the error , enable advanced logging as shown in KB01451 and look delete the Calendar entry which could be the cause of the error.
    Let me know how you make out.
    Thanks!

  • I fixed my Calendar syncing problems with Outlook

    I have fixed my "1 day out" syncing with Outlook.
    The solution below worked for me, but if you are unsure or a bit dubious then please take advice first....I'm far from a computor genius !!
    When I first downloaded 9.1.1.12 mine didn't work either for all the current calendar entries, but it did work for anything new.
    So here's what I did.
    Firstly if you have your i-Tunes set to "auto sync" when you connect your i-Phone then disable that. That's very important. Then in Outlook create a new calendar and just name it "calendar 2" or something. The new calendar will be completely blank. Then connect your i-Phone as normal. When you have the syncing page on i-Tunes in front of you click on the "info" tab and scroll down to the calendar section. Here you have the option to sync all calendars or selected calendars. After a while the new calendar you have created should appear in the calendar section. Check the box that says "sync selected calendars" and then check the box next to the newly created calendar, making sure the original calendar is not checked. Then scroll down further to the advanced area of the page where you can select information to be synced and check the calendar box. This area allows one way syncing from Outlook to the i-Phone. Once this is done click "apply" and the phone will start to sync. When finished your i-Phone calendar will be completely blank. Now go back to Outlook and "copy" your original calendar into the new calendar. Once this is done go back to the sync section in i-Tunes and repeat the sync again making sure the new calendar is selected only to sync and the calendar box in the advanced section is checked also. This will then sync your calendar back to your i-Phone correctly, well at least it all worked for me. Ideally it's best to then delete the original calendar from Outlook leaving only the newly created one there but I'm not sure it's always possible to delete the original one so just make sure you always use the new one and that when syncing you always have the new calendar selected.
    I hope this helps some of you if you're still having problems.
    My PC uses Microsoft Vista with Office 2003 and I have an i-Phone 3.1.3

  • (1) Calendar sync. problem using Chapura 3.1.2: (2) Can I sync more that one calendar in Outlook?

    A few items do not sync onto my Visor Prism (Palm 4.0.1 OS) calendar from my desktop computer (XP) Outlook (version 2003).  It is listed as "Unknown Error (FFFF)" in the HotSync Log.  Using Chapura 3.1.2.  Any ideas???
    Also, can these versions be set to sync more than one Outlook calendar???

    I am uncertain if Chapura makes products that allow for syncing to multiple Outlook calendars that are compatible with a device as old as the Visor. Best if you inquire with them directly.

  • 8130 Calendar sync problems with Outlook 2007

    I have Sprint 8130...and all is okay...until today.  I am used to Active sync (from my old HTC Mogul), not RIM software.  When I sync'd a week ago, the first time, all was great (accept for the confusion I still have about where the inet explorer favorites went).  Today, I plugged in for the second time.  All seemed great, except that now most of my calendar items are no longer in Outlook.  They are still in my Pearl, though.
    I have tried to sync the other way, but to no avail.  Ideas?
    Solved!
    Go to Solution.

    So, that did not work, and I ended up on a differnt board where I found the answer....it is a known software glitch with DM since 12/07.  It happens when you have multiple email addresses set up on your phone.  It can work fine for weeks/months, then one day it just happens.  It can happens no matter who your provider is.  RIM still has not fixed the sofware issue (unless the Altel .81 fixed it...).  It results from having 'multiple calendars' and only one syncing back to Outlook.  The only way to fix the issue was the following:
    a) Make certain Outlook is COMPLETELY up to date. Manually enter any calendar items on the BB which have not been synced over to Outlook.
    b) On your BB, look at Calendar > Options > and you will see the different calendars available. Go back to the main calendar page and and press Menu, and you can view the calendars for each email profile. Decide which email profile you want your calendar entries to reside under, and which is your primary email address for this.
    c) Go to Options > Advanced > Service Books. Highlight over AND delete the entries for ALL other email addresses other than your PRIMARY email address.
    d) Go to Options > Advanced > Default Services, and make sure ONLY the one primary email you desire is listed there.
    e) Now, connect your BB to your PC via USB, and open Desktop Manager.
    f) Now, with your Outlook completely updated manually, do this:
    1. Connect your BB via USB to your PC, and Open Desktop Manager on your PC.
    2. Open up Backup/Restore > Advanced.
    3. From Advanced you'll see a split pane screen. You won't see anything in the left pane. In the right pane will be the databases currently on your handheld device.
    4. Highlight on the right side your Address Book database (OR your Calendar database) and click the CLEAR button at the bottom of that screen.
    5. After it's finished, close the Backup/Restore window, and check the device to make sure the address book (or Calendar) has properly cleared out.
    6. Now, re-sync the necessary contact (or Calendar information) from Outlook (or your database) and you should be set to go.
    g) With all that completed, and your calendar appearing in BB... remove the battery on your BB (powered ON) and reboot the BB. This should resend the Service Books for the other email addresses you had deleted earlier. If you find after an hour they are not back, resend the service books from your carrier BIS site.
    h) return to Options > Advanced > Default Services and make sure your primary email is still the default email. You want to leave your primary showing in the screen, and save.
    I hope this might help some other people.  THere is talk about all Calendar syncing issues eing related to this issue (except obvious user issues like not syncing all appointments).
    Thanks for you time yesterday.

  • Calendar syncing problem with Outlook & iPhone

    My iPhone has stopped synchronizing with my Outlook calendar. New items I enter in Outlook on my PC fail to appear in my iPhone calendar after I syncronize via USB. I've seached the web and tried a few recommended fixes but no luck. Any ideas?

  • Itunes/Outlook Calendar Syncing Issue - UTF-8 Flavor

    I have had the usual and much discussed issue of outlook calendar does not sync with iTunes. The recommendations have been to remove iTunes and re-install, even blow away all the configuration files as well, and it even worked for me once. But not this time.
    I was running Windows XP, and all of a sudden the Outlook 2007 calendar just stopped syncing. I upgraded from XP to 8.1, and that was not fun, but inevitable, and still didn’t correct the problem. Now, if you never upgraded from XP to 8.1 – you can’t – at least it is not a direct flight. First, you have to upgrade from XP to 8.0, then from 8.0 to 8.1, and there is no upgrade in place from XP to 8.0. So what does an upgrade in place mean? Your applications and profiles are not carried over. Just your data (if you ask nicely) is carried over – but all applications have to be re-installed from scratch, and reactivated if there was license activation.
    So, forget about re-install of iTunes, I changed OS, reinstalled iTunes and Office 2007 from scratch. And still had the syncing problem. So, I wasn’t getting off easy.
    In searching, I found some debugging stuff which I tried, as follows to turn on logging:
    So, I ran the following:
    cd C:\Program Files\Common Files\Apple\Apple Application Support\
    defaults write com.apple.Outlook.client.exe ShouldLog YES
    defaults write -globalDomain SyncServicesLogEverything YES
    defaults write -globalDomain SyncServicesLogPersonalInfo YES
    And this turned on a lot of tracing. The tracing helped me understand what was going on under the covers, But I am not sure I was getting enough of the information that I needed to really zero in on the bad record.
    Now, I will pause and provide some observation of my specific Sync.
    An iTunes Sync on a Windows machine when using Microsoft Office and Internet Explorer is selected on the INFO tab of the page for the device.
    Selections include Contacts, Calendars, Bookmarks and Notes.
    One of the programs involved with Outlook Synchronization is: com.apple.Outlook.client.exe
    The program is called when Outlook data needs to be accessed, and is used for contacts, calendar and notes when those items are paired between the iDevice and Outlook. Bookmarks are usually paired with the browser, for example IE.
    During the sync operation, each of these are sync’d separately, that is why if you follow the sync actions, iTunes will reflecting what is being synced at the moment, for example “syncing contacts”.
    When syncing the calendar, and iTunes is running a slow sync, it reads the Outlook calendar using the com.apple.Outlook.client.exe and does processing of the recursion and time zone information.
    For example, for recurrence:
    [5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] Setting recurrence data <04300430 0d200200 000000ae 06000c00 00000000 00000400 00002120 0000e703 00000000 00000000 00000000 0000a0e7 980cc016 d10c0630 00000830 00000000 0000a005 00000000 00000000 00000000>
    [5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] 0 recurrence exceptions
    [5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] Reading the Extended Exception Info (i.e. Unicode data)
    [5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] Done making compatible recurrence
    For example, for timezone:
    [5484 @ Tue Jul 01 10:30:43 2014] [YSLog com.apple.Outlook.client.exe] Could not create a time zone from outlook name, tried using name (GMT-05:00) Eastern Time (US & Canada)
    Then the calendar entries are pushed, for example:
    ca965dbc4717d9488fafc9266f1f829304082700 =     {
            "all
    day" = 1;
            calendar
    =         (
                ca965dbc4717d9488fafc9266f1f829382800000
    "com.apple.outlook.freebusy" = Free;
    "com.apple.syncservices.RecordEntityName" = "com.apple.calendars.Event";
            "end date" = "2020-05-11 12:00:00 +0000";
            location = "United States";

    So, my SYNC fails, and I crash and burn with:
    [5484 @ Tue Jul 01 10:41:22 2014] [_ISDVLog com.apple.Outlook.client.exe] SyncServices assertion failure (nil != strUTF8) in [(null) (null)], SDLogging.m:641 could not obtain UTF-8 flavor of formatted string
    [5484 @ Tue Jul 01 10:41:23 2014] [YSLog com.apple.Outlook.client.exe] objcMain caught an exception:
    name      
    NSInternalInconsistencyException
    reason     : [(null)
    (null)]: could not obtain UTF-8 flavor of formatted string
    user info  : (null)
    call stack : (
    Now I’m back. So, during the extract and push of the outlook calendar entries, iTunes is building formatted strings. Now, Unicode is usually 16 bit (2 characters) Unicode, sometimes called double byte code. UTF-8 is single byte, so realize you can’t squeeze 16 bits into a 8 bit byte. However, you could if the Unicode string only contained characters that were valid for the UTF-8 character set. My interpretation of the error message above was that somewhere a formatted character string contained a “non-UTF-8” character and raised the assertion. Now, my issue with the excessive detailing from the logs was that – at least with the logging parameters I had turned on – I couldn’t figure out which calendar entry caused the exception to be thrown.
    First instinct was  that the last calendar entry in the trace was the culprit, so I deleted that calendar entry, ran again, the sync went up to the previous entry, and threw the exception. This gives me two theories: Either the sync was processing the next entry – which wasn’t printed in the trace yet – and failed, or the sync was going back to previous records – like reviewing the buffer. In either case, the trace wasn’t helping and it was all theories.
    Now what? What has everyone been saying? Issues with recurrence. And in the trace, as you see above as an example, “0 recurrence exceptions”, “reading the extended exception info (i.e. Unicode data)”.
    Now, I have no clue what that means. My initial guess was that recurrence exceptions (I had non-zeros on some) was an error. But further research I realized what it could mean was that these were situations where there were recurrence exceptions. What is a recurrence exception? Suppose I want to schedule a meeting on the 4th day of the month, for every month of the year. Well, except maybe July 4th, because it is a holiday and the office is closed. I would send the meeting invite, and then a cancellation for the July 4th. (I hear there is no simple way to do this). I now have an exception because I broke the recurrence chain. Other forms of exceptions is if I keep changing the location, or the body of the invite – e.g. every month I update the agenda, but only for one recurrence, not the entire series.
    So, keep in mind,  that if the issue is conversion to a UTF-8 character, and it is failing, then uninstall/reinstall of anything is not going to help if the real issue at hand is the data in Outlook and is not a coding or configuration issue. Now, sometimes it is an issue, but you need to see why the syncserver tasks are failing, and may fail due to other reasons including other data issues.
    So, what did I do? Well IO have 15K calendar entries, which, was taking an hour or two to slow sync (I call it a slow dance) and I was,spending days (maybe a couple of weeks) trying to fix this – and frustration was on the high end.
    I removed some of my older recurrences, and changed others from never expire to like 25 maximum occurrences. No idea which one worked, or even if it was a coincidence. However, the UTF-8 error went away, and then I moved to the next issue.
    Now, before we get there, with outlook 2007 finding recurrences is not difficult. Go into the calendar, and select appointment or list view (Outlook 2013 list view works ok). You can then sort on the recurrence column and see which (if any) items gave a recurrence pattern. Now maybe someone can figure out specific BAD calendar items that are throwing the exception to give us a better idea of what to look for and then report it so we can do further research.
    Now, once we can get the issue out of the way, stop iTunes from throwing an exception, we are not 100% done yet. By this time what is in Outlook and on the iDevice is out of sync. We need to get that message to popup asking us if we want to merge the data between the iDevice and Outlook. This can be important if you don’t want to lose data. My issue is that with iTunes 11.2.2 for some reason won’t do it, i.e. when I select “reset sync history” it doesn’t work. At that point I was forced to rename my iTunesprefs, the syncserver folder, and a few other folders. In this case, for Windows 7 and later, the folders in “Apple Computer” of both the local and roaming paths, and I had to cancel running tasks that had those folders open. One way or another, you want the iTunes message asking if you want to merge the folders.
    What can you do to help?
    Report success or failures using the information above
    Report if you are getting the same UTF-8 message, or if you are seeing other exceptions
    Report specific cases of calendar entries that you find that you have isolated to be throwing an exception
    Report any other logging/tracing parameters that you may find. It looks like you can turn on “ShouldLog” using the defaults.exe command for other tasks that iTunes runs.
    This syncing issue has been going on for years, under different iTunes versions, there has to be something going on and an easier way to troubleshoot this problem. I wish I had the time, but right now I fixed the problem I had and was able to resync my Outlook with my two iPads and iPhone.
    The only issue I have left at the moment is the message “the ipad xxx cannot be synced. An unknown error occurred (-54). – despite this error message, I am syncing, but the message is distracting and annoying.

    Yes - both have time zone support and are set to London/GMT
    The most recent of these aberrations was not even crossing a DST change - just a simple recurring event (which I've manually changed to single events by copy/paste).
    I just tried a new one which goes back 1 hr 27 Oct - when UK clocks go back. As it's a dummy apt I'll leave it and see if if goes back to the correct time on 27 Oct! In the meantime, I can't afford for my appts to get screwed up so will continue to do them manually!
    Thanks for your input.
