I don’t understand… you tried what file?

What I wrote was a run command.

Close Outlook, make sure it is not running.
Go to folder:
[b]C:\Program Files\Common Files\System\Mapi\1033[/b]
There should be the program scanost.exe in there.
Run it.
Click OK.
Click Scan all folders, this may take several minutes.
Select the Repair errors check box.
Click Begin Scan.
