Just installed Office 2007 on a new laptop for my wife with Windowns 7 Home Permium. Outlook was working OK for a few days but now ever since yesterday it won't open and gives the following error message:
"Cannot start Microsoft Office Outlook. Cannot open the Outlook window. The set of folders cannot be opended. The file C:\Users\Lyn\AppData\Local\Microsoft\Outlook\Outlook.pst is in use and cannot be accessed. Close any application that is using this file, and then try again. You might need to restart your computer."
As far as I can see there is no other application running, and I have restarted the computer more than a dozen times, but always the same error message when you try to open Outlook.
I have downloaded all the updates, including office 2007 SP3. I have tried to run Scanpst but it cannot locate the Outlook.pst file presumably because it is in use (or it thinks it's in use) by another program/user. Additionally you get the same error message when you try to open Outlook in safe mode.
