Outlook 2007 and corrupt PST file. Connected to exchange.

Basically, Outlook 2007 has corrupt the local PST version of a user's mailbox. Outlook couldnt even pull down todays emails so I ran scanpst on the ost file in settings for outlook.

Because we use exchange, would it be best just to remove the account from outlook and join it to exchange again and then the mailbox would be downloaded again?

I logged into the web access and todays emails are there. Is it only worth running scanpst on a local only mailbox.

The mailbox is 6gb too, could this be how it got corrupt? The user did used to use entourage on a mac and eventually he has been moved to a PC which is standard at our office and our exchange server.

Perhaps outlook doesnt deal with massive mailboxes as well as entourage? He's the only user I have this problem with.

When running the repair option in scanpst on the ost file it seems to have frozen the computer with explorer.exe using 100% cpu.

With being exchange connect I presume there is nothing in the local pst that isnt in the exchange mailbox.

Am I right? Or is it possible that when the crash of outlook happened that caused the corrupt, the exchange mailbox could be damaged too and creating a new account/connect to exchange may result in the same problem?

Hello jdunnill,

To recreate a new OST file, move the old OST file to another location, and create a new OST from Exchange. Nothing should be lost.

For repair OST file, use Scanost.exe
http://office.microsoft.com/en-us/outlook/HA010563001033.aspx

Yes, 6 GB file size could be cause of corruption.  User should archive some emails to reduce the size under 1 GB.

Hope this helps!
