A user reported today, that he has been receiving several of these every couple of hours. They appear in his default Inbox folder. I have never seen this error before.

 
13:21:08 Synchronizer Version 14.0.6025
13:21:08 Synchronizing Mailbox '**** *******'
13:21:08 Synchronizing server changes in folder '**** ******** - Calendar'
13:21:08 Downloading from server 'mail.***.com'
13:21:08 Error synchronizing folder

13:21:08 Done

Open in new window


The user receiving the error, has been granted full permissions by the owner of the Calendar.

Clicking the link takes me nowhere useful.

Any ideas?

Thanks.

Are these users are in Cached Mode or Online Mode?

Author

Commented:
The specified user is in Cached mode.

The reason I have him in Cached Mode, is that he has multiple Exchange accounts that he needs to send/receive from. When in Online Mode, if he sends from an account other than his primary, the outbound message queues in his Outbox indefinitely, never sending. The only remedy I found for this, was to put him in Cached Mode.

If you are using outlook 2010 check this and install sp1.
This will fix the issue.


This also may be due to MAPI add-ins

Try disabling the Outlook ActivIdentity Extension in the Outlook Add-in Manager :

Tools --> Options --> Other (tab) --> Advanced Options --> Add-in Manager --> Restart Outlook.

SP1 is already installed. Since the original posting, I have learned that there are additional users experiencing the same issue, but with different calendars.

I could find no such add-in listed.

Some users have Outlook 2010, and others Outlook 2007. We are running Exchange 2010.

Any other ideas?

9:49:34 Microsoft Exchange offline address book
9:49:34 Download successful

I'm at a loss, here. I have no idea what is causing this. Multiple users are now reporting the same symptoms. Any ideas?
We have the same problem (see error), User B granted User A permissions for his calendar. Office 2010 SP1 is installed, Outlook ActivIdentity Extension add-in not there. Thought this one had maybe something to do with enabling web-based distribution of the offline address book, but that does not work. Checked the internal and external url of the OabVirtualDirectory seems ok. internal = https://servername.company.nl and external = https://mail.company.nl. Any ideas anybody?

Does anyone have a clue on this issue.

Thanks.
If you only give the user "Reviewer" rights (especially to only certain areas, like Calendar) & are using Cached mode, then:

You should disable "Download shared folders" in ... Control Panel -> Mail (or Mail 32-bit) -> Email Accounts -> Change -> "More Settings" -> Advanced (tab) -> Cached Exchange Mode Settings.
