Couple steps you may apply...
1. Repair the offline file with a Microsoft utility called SCANOST.exe. I’ve seen this file
reside in a number of different locations, mainly within Program Files. It might be best to
search for it with Windows or Google Desktop. SCANPST.exe will also work, though you’ll have
to go digging for your outlook.ost, which should be near c:\Documents and Settings\ %profile
%\ Local Settings\ Application Data\ Microsoft\ Outlook\ outlook.ost. If your file is
significant in size, you’ll save a lot of time with the repair operation by not creating a
backup. Because if the repair finishes successfully and Outlook still bombs, you’ll need to;
2. Shutdown Outlook completely, including any runaway outlook.exe processes in the task
manager. Open Mail in the Control Panel and before you delete your profile completely, write
down the server settings! There’s no need to worry about backing up your mail as it’s stored
on the Exchange server. (Essentially, you’re deleting that outlook.ost when you drop your
mail profile.) Now, start Outlook and it will create a new profile, where you’ll configure
the server with the information you wrote down previously.
