Re-occuring .ost file corruption

medardtaber · Jun 24, 2015

We have a practice wide re-occuring issue in which users .ost files become corrupt.

See error:

"Unable to open default email folders. The file C:\\microsoft\outlook\outlook.ost is not an offline folder."

We are on Outlook 2007 (12.0.6423.1000 SP2 MSO), office 2007. Occurs on different PC's & laptops, happens on 32-bit and 64-bit OS.

We know that deleting the .ost file or re-creating the mail profile will fix this issue, however, we have numerous Users around the world, which this is not an option. Moreover, this is a re-occuring issue and want to get to the problem rather than the work around.

Advice and Suggestions are welcome!

5. Enter a name for the folder, and select the Desktop as the location. Click "OK" to select default settings. Drag the "Personal Folder" from the Outlook window to the new folder to move OST files to the personal folder. When the computer syncs with the server, all of the OST files can be copied there.
