I have an executive level user that has recently encountered a pretty strange problem with Outlook 2007 in cached exchange mode. He's got a pretty big mailbox - about 4 gigs - which recently started a constant "updating inbox" sync routine even when he doesn't have any new messages available on the server. Unfortunately this pretty much renders Outlook useless for him performance-wise so the sooner the better in getting this issue resolved since i've had him set up in webmail the last few days while i've been troubleshooting.
Here's what we've tried so far:
* creating a new mail profile
* deleting and resyncing a fresh OST
* modifying some antivirus settings -- we run ESET antivirus, and we checked the option to "disable checking upon inbox content change" after some research. this helped to speed the sync process up but it still continually starts and stops the sync.
* ran a repair of office
* uninstalled and reinstalled Outlook
At this point I'm beginning to think it's not a local issue at all and that it's something on the server, likely mailbox corruption. I ran a test PST export of his mailbox and in the Exmerge logs I am seeing thousands of records like this:
[21:55:35] Error copying message with subject 'Your Junk Mail Digest: email@example.com' in folder '\Inbox'. (MAPI_W_PARTIAL_COMPLETION)
My question now is on the next step. If I run utilities such as ESEUTIL and/or ISINTEG, will that help to clean up the corrupted items in his mailbox? Is there a better way to identify corrupted items in a mailbox then just running Exmerge?
Thanks in advance for any help you can provide.
