Offline Folder Errors

Try configuring offline files through GPO of the particular OU. (You can add all users in an OU you want regulated) Right click the OU, Properties, Group Policy, New, then Edit. Go to Computer Configuration Node, Administrative Template, Network, Offline Files. There are several preconfigured policies in this window which you can either disable or enable depending on the security needs of your organization. Hope this will help.

Sorry, I can't offer a solution but I may be able to add more detail to the problem. I'm having a very similar problem with one of my clients' systems. I too have recreated the OST file with no luck. I also synchronised each folder seperately until I found the one that was causing the problem. I then created a new folder and moved the emails from the troublesome folder to the new one, and then deleted the old one. When I re-synchronised, I found the same problem with the new folder, so I can now rule out a corrupt folder.

Next, I created another new folder and moved batches of emails from the troublesome one to the new one, re-synchronising as I worked. Eventually, I managed to move all the emails across and the new folder synchronised without problems. Notice that I havn't found the 'problem email' I was expecting to find.

Now the whole system synchronised without a problem, and I really have done nothing. However, one day later and the problem is back. I had not deleted any emails during this process, so it doesn't seem to indicate the size of the folders to be a problem.

I hope this provokes some thought within those highly technical brains out there! I'm a general IT consultant and so although I understand the general principles of the exchange system, I don't profess to know all the ins and outs of this particular system, so please explain things simply if possible!

If using a 3rd party Antivirus utility on the server and the server is at Exchange 5.5 SP3 then you will want to read the Technet Article Q269439

If the Server's ORG FORMS LIBRARY was deleted and recreated then you will want to read Technet Article Q162703

If your server is at SP2 then you will want to read article Q185692, which btw recommends upgrading to the latest service pack.

If none of these do the trick then please post the error from the Sync Logs. There are numerous articles related to OST Synchronization problems. Those that I mentioned were the top 3 I ran into with my customers.

The articles can be found & read here: http://support.microsoft.com/

Good luck.

Just for the record, I'd like to thank Rick for his suggestion. My problem was solved by adjusting the Antivirus scan setting described in the KB article he refers to. Thankyou!
