Problem: One outlook 2010 client won't update emails when in cached mode. With cached mode disabled, the email displays and will send/receive. The other outlook clients work correctly in cached mode. When outlook is opened for this user in cached mode, no error is displayed, and it sits. If the user presses send/receive it runs through and gives error 0x80004005. Layout: Exchange 2003 standard running on server 2003 standard. Workstation is windows 7 with outlook 2010. Tried: I have removed and recreated the OAB in exchange with no change for this user. On the same machine, using a different user, the connection works in cached mode with no issue. I created a new profile for the user and tested, this exibits the same issue.

Did you try closing Outlook and any other service on the users machine that may be accessing the OST, i.e. indexing etc then killing off any OST related to the user and then restarting Outlook Have you tried this on another machine to see if its truly account related?How did you do the Exchange Recovery?Troy Werelius www.Lucid8.com Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline EDB's and Live Exchange Servers with Lucid8's DigiScope

I have tried closing outlook and verifying it is closed, renaming the .ost file and restarting outlook. = no change I have tried the user on another computer, same result. And the user who normally uses the computer has no issue with cached mode. The exchange recovery was from bare metal. Installed fresh 2003 sv, installed the symantec client, restored machine image from backup exec 2010. Restart, fix errors and start a new blank db for user store and public. Started restore of exchange from backup exec.

Correction, I just was told that the user exibiting the issues can, login to the domain on another similar workstation win7 64 and outlook 2010. And then cached mode works properly. So the issue seems to be only with this user on this computer. I have not renamed the users profile and attempted with a fresh profile yet.

Any update? If no more question on this thread, we may mark it as answered. Thanks. Fiona Liao TechNet Community Support
