When you open MS Outlook you might get error “C:\Documents and Settings\Owner\Local settings\Appliation data\Microsoft\Outlook\outlook0.ost is in use and could not be accessed. Close any appliaction that is using this file, and then try again.”
You might encountered this problem due to various reason and one possible reason is that the .OST file itself might corrupted.
To resolve the problem you can rename the outlook0.ost from the original location. When you restart the Outlook you will see a new outlook0.ost file created in the said location
Note : If you do that then there is a possiblity of loosing the existing mails.
If you could get some tools that convert .ost to .pst then you would be able to import the emails to the MS Outlook
