Synchronize errors in Outlook 2010 on Exchange 2010 SP1

Hi all,

I have a user running Outlook 2010 in an environment with Exchange 2010 SP1. He's getting these synchronization errors and data on the server is not being deleted when he deletes mails from his mailbox. This means he has reached the size limit. The messages looks like this:

10:36:59 Synchronizer version 14.0.4760
10:36:59 Synchronizing Mailbox 'username'
10:36:59 Synchronizing local changes in folder 'Sent'
10:36:59 Uploading to server 'servername'
10:36:59 Synchronization of some deletions failed.
10:36:59 		 [0-130]
10:36:59 	   1 item(s) deleted in online folder
10:36:59 Done

Can anyone please help me here?

Thanks,
Ronnie

Disable cache mode. Remove or move OST, Enable cache mode again. Let it create OST again. Then test the result

Doesn't this only stop the errors from being logged? I've cerated the registry but by now the local data is 707 MB and the serverdata is 962 MB. I don't understand why items are only being deleted locally and not on the server.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

707MB is your entire mailbox and not just the inbox?

Hi,

renaming the ost file and creating a new seems to have fixed this.

Thanks,
