Calendar not synchronizing with Exchange server

2 weeks after upgrading to OS X 10.9.4 Calendar is not synchronizing with our university Exchange server. Problem is with 2 different computers, iMAC and MacBook Air (both with ethernet and wifi)). Mail is working/synchronizing fine. Outlook calendar (on both same Macs and Parallels PC) is synchronizing fine. iCLOUD events are shown.
Noticed that it is a one-way problem- not downloading/synchronizing from the server but events entered on both problematic Calenders are found in Outlook (and of course in the OutlookWebApplication). Practically I can't work anymore with Calendar.
Tried to delete Caches - didn't help. Tried to restore old preferences- didn't help. Any help? Thanks!!

Still happens with 10.6.2.
It clearly states in mail help that this should happen -- yet it does not.
Anyone?

Calendar will not sync with Exchange server or most Google Calendars

Hi,
I am writing about my wife's brand new Samsung Charge on Verizon. We managed to setup both her gmail account and her work exchange server account fine, except for the calendars:
Her Google calendar shows up fine, but I am unable to even see any other Google calendars that she has access to (both her own secondary calendars as well as calendars that others have shared with her) in order to select them to be visible.
Her exchange calendar says it is enabled (on the list of available calendars), but no events at all show up.
This behavior is with the latest software updates on the Charge (2.2.1 firmware, I510.EE4 build) using its stock calendar software. I did notice that if I use Smooth Calendar, it does list all of her Google calendars under its listing of available calendars, but it still only shows data from her primary calendar. This is also true using the Touch Calendar app, which leads me to believe that there is some problem within the Google Calendar sync software that is not allowing her calendars to appear correctly.
Thanks!

Outlook 14.4.8 not synchronizing with Exchange 2007 anymore (shows "downloading" but no new messages shown in inbox"

Outlook 14.4.8 on iMAC Retina and Yosemite 10.10.2 is not synchronizing with Exchange 2007 anymore (shows "downloading" but no new messages shown in inbox".
Accessing Mails with Webbrowser and from Windows Outlook is working correctly.
All Macs (also the ones with OS 10.6.8) do not anymore show any new messages in inbox.
Restarted Server, tried to disable autodiscover on macs and deleting/adding account and repairing database does not fix the problem. Also restarted server several times.
We have the same problem on 2 imacs retina with yosemite and on 2 mac pro with 10.6.8 and different office 2011 versions.
i tried to configure the exchange account in apple mail on yosemite and it also states "connected" and does list some folders but no new mails are getting in.
Windows clients and outlook on them works and syncs fine, and also when connecting via webbrowser at owa it must be a mac-specific/webdav issue.
exchange 2007 Sp3 Version 8.3 (bild 83.6) and Update Rollup 15 for sp3 (automatic updates "HIGH" for server and clients)
there is one update popping up again and again even after everytime successull installation: Windows Mlicious Software Removal Tool x64 - October 2010.
i tried to configure a new user with empty mailbox and configured it with microsoft mail (mac - yosemite) as exchange and was able to send a mail from there (even if quite delayed).
but there are not coming in any mails.
same exchange accounts triggered by imap do work and also via owa.
Exchange Accounts in Outlook for MAC and also in Mail (Yosemite) do show the folder structures but there is no mails showing up. I can send mails from the exchange accounts created but they seem to be processed with a delay of like 15minutes and outlook
is giving error "end of file reached" but messages are send after some time.
Does seem like EWS is extremely slow, to slow perhaps to sync and therefore ending in timeout.
Also i cannot reach the server from externally over ssl https 443. if testing port 443 of exchange from outside the port seems closed even firewall settings of sbs 2008 and sonicwall ports are correctly open.
could it be there is something in regarding webdav which is very slow and leading to timeouts ?
in application log i do have the following two information events every few minute:

Hi,
Since Outlook running on Windows works well, it seems an issue on the Mac side. I suggest ask Mac for help so that you can get more professional suggestions.
More information for your reference:
Please try to verify whether there is any expired certificate from the computer personal store.
If it is the case, please remove them.
Thanks

Outlook 2013 not connect with Exchange server 2013 in internal network

Hello All,
I Have two Exchange server 2013 in our environment. Both server install mailbox and CAS role. After configure exchange server 2013, Outlook 2013 not connect in internal network. I have configure outlook manually. i tried by using the suggestion from blog
but not work. Outlook show that Server cannot connect/ server name could not be resolved. in outlook setting i also put exchange proxy setting. In exchange admin center i have changed the OWA, OAB, Auto discover name. But still not work.
I know that outlook can be connect from external by using ssl certificate and publish outlook anywhere but i did my configure from internal network.
Can you please suggest as soon as possible.
Thanks,
Parvez

Hi,
Firstly, I’d like to explain, same with external users, internal users use Outlook Anywhere to connect with Exchange server and use Autodiscover get all settings.
Thus, let’s try the following resolutions:
1. run the following command: get-clientaccessservice |fl autodiscoverserviceinternaluri
2. check if the host name in the above URL is in the DNS server and there is a DNS entry about the host name points to the proper IP address.
3. Check if the above host name is in your certificate.
Thanks,

CUIC not synchronizing with NTP server

Hi all,
I am working with a customer who has CUIC 8.0(4)
Recently, we installed the RTMT tool in the Operations Console and noticed an alert indicating the server is not synchronizing with NTP.
After running the command "utils ntp status", I got the following output
admin:utils ntp status
ntpd (pid 17892) is running...

I restarted the CUIC server, removed and re-added the two IPs as NTP servers, and changed the registry as recommended in this link:
http://htluo.blogspot.com/2009/02/ntp-network-time-protocol.html
But the problem is still there.
Any advice? I am taking the same action plan as if it was a CUCM instead of CUIC since they have the same OS (because CUIC issues are not that common) and I welcome any suggestion that applies with CUCM.
Appreciate your replies,
Sahar Hanna

Hi Anand,
Thanks for the reply.
It seems in the above link that the CUIC version is 8.5.x mine is 8.0.x so I don't know if it applies also here
In addition, I found out that this problem is a bug CSCte17541 and the workaround is to point all systems to a reliable UNIX NTP source, or a Cisco Router running NTP

Synchronizing with Exchange Server Calendar

I have a 'Calendar' table that is part of our database structure i.e. a Calendar record will contain a unique indentifier, a start date, end date, subject and note field
I would to like write a windows service (probably Delphi or C#) that every so often will Synchronize the data records in the Calendar table with the Exchange Calendar.
Calendar records can be added, changed and deleted at the database end but can only be edited or deleted at the Exchange side. The Synchronization would have to work in both directions i.e. Update with the most recent changes.
I have been looking at MAPI and Exchange Web Services as a starting point. Maybe there are other alternatives or 3rd party solutions that I should consider ? Has anybody got any experience of performing a task like this or able to offer any advice on how
to tackle the task.
Any help would be very much appreciated.

Hi,
According to your description, I understand that there is need to write a script or service to achieve Exchange Calendar syncing and only allow updating in Exchange server side. I suggest we can ask a question in Exchange development forum for more help:
http://social.technet.microsoft.com/Forums/en-US/exchangesvrdevelopment/threads
The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

Daily Problems with Mail Synchronizing with Exchange Server

Our office uses Comcast Business Class Service, which uses 2007 Exchange Servers, for internet access and email. I upgraded my MacPro from 10.5.8 to Snow Leopard 10.6.2, using the Upgrade DVD. The upgrade process kept my original Leopard Mail settings, which were using POP. At that time, I had not problems with email.
Unfortunately, awhile ago my Mail Preferences became corrupt, and I had to delete them. Upon relaunching Mail, the application wanted to use the new Autosync method to connect to the Comcast Exchange Server. Using POP was not an option.
I must say that I am less than impressed with the way Mail integrates with Exchange Servers. I have daily problems, and experience these problems multiple times per day. When they happen, they slow my email communication down to a crawl; sometimes for as much as an hour.
Specifically, the problem appears to be with Mail's ability (or inability) to properly synchronize with Exchange Servers. I get he spinning pizza icons next to the two Exchange email accounts I have in my Mailboxes source column. Opening the Activity window shows that the synchronizing process has slowed everything down. This results in not being able to send or receive email until the synchronizing is complete. And as I said, that can sometimes take as long as an hour.
Stopping the process in the Activity window does not resolve the issue. Nor does quitting and relaunching Mail. Because the next time Mail attempts to connect to the Exchange Server, it will try to synchronize yet again. The problem has become so chronic, that I often have to resort to using Webmail while waiting of the synchronizing process to complete.
Incidentally, the mailboxes that are synchronizing are empty! I am meticulous about keeping my Inbox, Sent, Drafts, and Trash mailboxes empty at all times. I do not use To-Do's, Notes, or Calendars of any kind on the Exchange Server, so there is no data to even sync!
Has anyone else experienced this problem and found a fix? Other email accounts I have, which use POP or IMAP, do not have this issue. There does not appear to be away to abandon the Autosync Mail setup and revert back to POP. If there is, I will do it in a heartbeat.
Thanks.

Found a solution that works for me. Delete the problem account that's using AutoDiscover to sync with the exchange server. Before doing that, however, you will want to clear out the Inbox, Sent and even Trash folder for that account, as deleting it will remove the messages that currently reside in those folders. Just simply move them to another folder. You can move them back after re-creating the account.
The second step is to re-create the account. Do this as you would normally, and enter in your name, username and password. THE TRICK: Press and hold the Option key when you click Continue. After Mail connects to the server and verifies your account information, you will then have a pull down menu that will allow you to choose Exchange Server, IMAP and POP. Simply select POP or IMAP, then fill out the rest of the fields.
Viola! No more problematic Exchange Server syncing issues.

Help! iPad calendar sync issues with Exchange server

Hello, I've googled this issue and haven't come across with any definitive answer so I'll put it up here to see if anyone have any idea(s).
iPad 3G/Wifi working fine for over a month (firmware 3.2.1) synching with MS Exchange server (only Mail account on the device), over the weekend, calendar entries have disappeared. I've deleted the mail profile and reset it up again, here's what happens, email starts to pull down, same with contacts and Calendar entries, then while Calendar App is open on Month view I can see that the appointments are also being sync then after about a minute, all the entries will just disappear, if I wait a few more minutes, the appointments will start to repopulate again then disappear again after about a minute! Email and contacts are fine, just this Calendar issue.
More background data: User is using an iMac with Entourage 2008, his EA has full email rights to his mailbox and have his email profile on Outlook 2003, both are showing correct Calendar entries on desktop, have also checked the account on OWA and it looks fine there as well.
I'm guessing a corrupt calendar entry (possibly re-occuring appointment)... Does any one have any other thoughts?
Any help would be highly appreciated.
Thanks!!!

I have been having very similar issues to those described by Imola. The calendar appears to try to load, and a few appointments may show up, but then they will all (or almost all) dissapear. My company uses Exchange 2003.
Occassionally, deleting a large attachement has helped. But not always. Several times in the past, I have exported all my calendar entries as a .csv file, deleted all the calendar entries in Outlook, and then re-imported the .csv file. While this always works to re-populate my calendar, it also strips functionality (like recurring appointments).
This is very frustrating, and results in me havinging to rely on my Blackberry while traveling, when I would like to just trust the data in the iPad. A web search clearly shows that many people have this issue, but I have not yet seen any direct responses from Apple. I hope this is addressed soon.

TS3276 OS X Mavericks Mail does not sync with Exchange Server

After moving to Mavericks, mail, contacts, anc calendars do not sync with our exchange server. It will set up the first time and then stop sycning. Is there a way to delete the mail app and reinstall. All other Apple devices sync with the exchange server with no issues.

It was my DNS settings. I had my Airpot pointing to OpenDNS, and for some reason iCal and Address Book could not find their way to my exchange server. I changed the setting to use my ISP's DNS and now everything works fine.

Upgraded to Mountain Lion and Can't Get Calendar to sync with Exchange server

Mac calendar syncing problem with exchange server

Hi, I have been having problems syncing the calendar on my MacPro (late 2013, with OX Y Yosemite, even the earlier operating system) with my work calendar (exchange server). It keeps giving an exclamation mark and the error message is "There was an error attempting to send your changes to the exchange server.".
Mail syncing on Mac with the same exchange server is working perfectly.
I also have iPhone and iPad, and never had issues syncing calendar nor with Mails.
I have tried to create a separate log in profile on my mac and attempt to sync calendar, it makes no difference.
Any advice?
Thanks Shu

There are several ways of exchange server recovery.
Reset the computer account for the lost server.
Install the proper operating system and name the new server with the same name as the lost server. Recovery won't succeed if the server on which recovery is being performed doesn't
have the same name as the lost server.
Or try FREE DEMO of
Recovery Toolbox for Exchange Server http://www.exchangeserver.recoverytoolbox.com
Seriously? Can you recover data or repair the EDB file if it isn't there at all? JET_errInvalidDatabase says database isn't present!

Windows Mobile 6 not syncing with Exchange Server / Error Code: 0x80072F06

Just got my Dopod 838 pro with Windows Mobile 6 installed. Having this problem when trying to sync with corp. Exchange server:
The ActiveSync circle on the phone turns yellow/brown, clicking the Error message it says:
The Security Certificate on the server is invalid, please contact Exchange Server Admin or ISP, to install valid certificate on the server.
Support / Error Code: 0x80072F06
That's the problem. My phone doesn't have a Data Link connection problem as I am able to go online with it, also the company's Exchange Server is good, a few days ago I used my Windows Mobile 5 to sync with it without a problem. (but then I lost the phone)
Can some one help? Thanks.

Can u help me here?
I have a windows 6 mobile devices (all) that are having an issue connecting to my exchange server. I am pretty useful with certs but this one is baffling me. I have a windows 2003 sbs server. I recently created a san cer on the server and since then my Windows devices cannot synch. I belive I have setup correctly, or not?? Ther error and the steps are below...
ERROR ON DEVICE:
The security certificate on the server is not valid.Contact your exchange server administrator or ISP to install a valid certificate on the server:
support code: 0x80072f06
STEPS I USED TO CREATE SAN:
1. Created certificate using article http://support.microsoft.com/kb/931351/en-us
I added the following as SN: MAIL.EXTERNAL.COM (my external dns record for mail server)
And added the following for SAN: SERVER01 (my mail server name )
SERVER01.INTERNAL.LOCAL (my mail server fqdn)
2. Exported Root CA cert and imported to my phone
3. configured active synch to connect to mail.external.com on 443
I believe these are the correct steps. I would liked to have been able to export the SAN cert from IIS with private key and install on phone but the webserver template doesnt allow you to export private keys. I also cannot create a dubplicate webserver template to allow the export of the private key as you need enterprise edition of windows 2003 to do this.
So I am at the end of line I tried exporting the cert without the privtate key and importing it but still keep getting samer error.
Why of Why does it not like my cert?
I have just noticed now when I browse to the same address for OWA externally I am getting the error on my browser too even though I have the cert installed on my laptop

Agenda can not communicate with Exchange server

Hello,
Whenever I start my agenda app on my MBP, I get the message: Agenda can not store the agenda <name> on the Exchange server. I use Office 365's Exchange server. When I use Outlook to communicate with te same Exchange server, there is no problem, but I like to use the native Apple Agenda app.
Anybody got the same problem, and more important, the solution?

Justin, I don't know if this will help but I do remember running into this in the past.
I ended up setting up my mail using our webmail server. Also instead of using my email address I used my login credential in front of the @. Our login credential is not the same as our email. So instead of [email protected] I went with [email protected] and used my password for password at setup of an exchange account. This worked like a charm.

IMAP still not synching with Exchange Server... Come on Apple!

I have IMAP set up to my company server from the iPad. Reason being so that I can manage emails (delete, move to folders etc) whilst working off-line.
But any changes made via the iPad are not synching and updating on the Exchange Server once back on-line.
Really hoped iOS4 would fix this, but no. This really is the most useless tool for a regular business traveller. Not being able to catch up on email and sort, delete, reply etc on short haul European flights is in-excusable for a 2010 business tool Apple!
Unless I'm missing something??!!
Message was edited by: Tuskaa7

Yes thanks Graham.
It is a big oversight in my mind and one which makes me carry a laptop most times, somewhat negating the need for the iPad. Thus actually adding a business tool I need to carry, rather than reduce in size and weight etc. I real shame for me and one which actually makes the iPad almost redundant most of the time.
I know having searched these forums and speaking with colleagues etc, it is a common feeling and one which Apple should address asap in my mind.
Thanks anyway,
Keith
