Mountain Lion calendar and notes sync problems with exchange server via WLAN

After upgrading to Mountain Lion calendar and notes do not sync anymore with my exchange server via WLAN. There are no syncing problems via ethernet if WLAN is deactivated. Mail works fine with both connection types. Similar problems known? Solutions?
Thanks for any ideas.

Exact same issue ... cropped up in the past 2 weeks. Constantly syncing and re syncing. Watching calendar events show up and disappear. Tried all the normal stuff including deleting and re setting up the entire acct ... no luck. It built out the whole calendar correctly ( from what I could tell) and then started to sync again and appointments randomly appeared and disappeared .....

OS X Mountain Lion calendar app not syncing with iPhone 4 calendar.

After installation I noticed that my OS X calendar was not syncing with my iPhone 4 calendar running version 5.1.1. Any sugestions to fix this issue.

Please note that all my settings are exactly the same as they were in Lion. I do not use iCloud and I like to sync thru iTunes via WIFI and USB. After further research I have discovered that this issue is seems to be with Mountain Lion. Obviously, Apple needs to update iOS 5.1.1 or release a fix for Mountain Lion.

Iphone not syncing anymore with exchange server

my Iphone has worked perfectely for a few months with exchange server for synchronising agenda's and email receiving and sending out via exchange....
Since a few days not working anymore, everytime info wrong pasword. All settings are correct, what could be the problem. My Iphone receives direct ema-ils, works on internet...and can sentout, my mobile me works perfect, only not the exchange server is not working anymore.
please help.

I assume from what you posted that you mean the user has created contacts in the "default" address book instead of in their Exchange address book.
If that's the case, then can not be "moved" to the Exchange address book. The user will have to export them from whatever contact manager they are syncing that particular contact list with and import them using their Outlook client, or they will have to re-enter them in the correct address book.

Calendar Will Not Sync Correctly with Exchange - Appointments come and go

After 10 weeks of no issues, all of a sudden my calendar sync will not work. Mail and contacts work flawlessly. I am syncing to an exchange 2003 sp2 (my IT guys tell me) server. Supposedly nothing has changed on their end. I haven't changed any settings on the phone. (Added a couple ringtones the other night but can't believe that would have changed anything here.) I sync to itunes at home (win-doze xp/itunes 9), but don't sync any calendars via itunes. What's really weird is that the calendar appointments will disappear completely ... then about 2/3rds of them will pop in ... then disappear, etc. The "Genius Bar" doesn't have an answer other than to reset factory defaults so I came home to back up my camera roll first; not shot up about that "solution." Any help greatly appreciated - Paul.

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!

I am getting sync problems with Exchange Server and local outlook. Error code is 18439. Does anybody have an idea what the problem might be?

I am using Outlook on my Imac, which is linked to the Windows Exchange Server. All off a sudden I keep receiving messages saying that the message Re: xxxx cannot be synchronized with the exchange server. When I delete the message from my local mail box, all is fine, but after a while another one pops up. The error code is 18493. Does anyone have an idea what could be going wrong???
Thanks for your help already now!

Hello Wolfgang,
I get the same error, but I cannot figure it out too. I hope you or I get some responses back! I do not know why there isnt an edit feature in outlook to acknowledge the individual alarm so it does not alarm again!

Did Mountain Lion break calendar and note sync between the Mac and iPhone?

When I was running Lion, my calendars and notes synced properly between my Mac and iPhone (with notes going into Mail.app). After upgrading to Mountain Lion, the notes on my Mac were moved into Notes.app and my calendars appeared to be unharmed. I've recently noticed that neither my calendars nor my notes are syncing between my Mac and iPhone.
I use iTunes to sync my data (either via USB or WiFi) and have no interest in moving to iCloud. I have tried the suggestion of enabling iCloud sync on my iPhone, then disabling, as well as telling iTunes to overwrite the calendar data on my iPhone. Neither of these approaches has solved my sync problem.

I found a solution to my problem. Hopefully it helps someone else too.
I deleted the following file and folder:
~/Library/Calendars/Calendar Cache
~/Library/Calendars/Calendar Sync Changes/
When I synced my iPhone, I was presented with several sync conflicts to resolve. I resolved them and applied the changes immediately. Now my Mac and iPhone are in sync and I've confirmed that changes are syncing from my Mac to my iPhone (I'll confirm that it works the other direction tomorrow when I can look at my calendar at work).
This is the thread that helped me:

Currently running Lion, want to move to server, do I need to upgrade to Mountain Lion first, or will it come with the Server purchase?

No. Mountain Lion Client and Server are two separate purchases and downloads. You will need to upgrade to both.

Iphone/ipad not syncing meetings with exchange 2010

I'm having a problem. There is only one user out of 25 this is affecting. Every so often he will change an appointment by moving or deleting it in Outlook but isn't updated on the iPhone. He has an iPhone 5 with the current OS, the iPad is the 2nd generation with the current OS,.and is connecting to our Exchange server. Any assistance is appreciated.I

Mountain Lion Contacts app not syncing properly

http://support.apple.com/kb/TS3998
Following the advice in the article DID NOT resolve my syncing issues with the contacts app. Contacts that I create on the Mac DO NOT sync to iCloud or my iOS device. However contacts created on my iOS device or iCloud DO SYNC to my Mac. I have done the following which HAS NOT resolved my issue.
1) Systems prefs ---> iCloud
2) Disabled and enabled Contacts
3) Rebooted
Is there anything else I can try?
Also I am still getting duplicates in my contacts and I am having to manually delete a number of entries even after following the advice in this article which cleared about 80 of my duplicates but thats all.
Thank you for your help
John

Please note that all my settings are exactly the same as they were in Lion. I do not use iCloud and I like to sync thru iTunes via WIFI and USB.

Mountain Lion upgrade and Internet connection problems ?

Since I upgraded my Macbook Air, it does not want to connect to my home Internet network anymore. My Ipad, Iphone and tablet PC are all working fine, but to connect to the network I need to restart and even reset my router to be able to connect. Needless to say, I lose connection when it gets into sleep mode and when it is shut down. Anyone having the same problem or a solution ?

I'm having similar problems with a 2012 13" MacBook Air. It's brand new, came installed with Mountain Lion.
I get disconnected from the wireless randomly and the wireless icons turns gray. Like you, I have an iPad, multiple computers and they all work fine.
Instead of restarting the router, I go into Safari and do a network diagnostics and it picks up the connection easily enough.
No solution as of yet, but I posted a topic here if you want to follow it:

Mountain lion calendar dialog not closing

My Mountain Lion calender suddenly started to refuse to close editing dialogs. It started when I tried to change the calender of an event (created by invitation from another person). The 'done' button has no effect.
I can doubleclick another event thus changing the open edit dialog to that event, but I cannot close the dialog. If I quit and reopen the dialog reappears.
I can save no changes nor create new events.
I've quit and reopened, I havge restarted the Msc (MavBook Air, early 2011).
Anyone else?
