    • In my case Outlook 2007 would not open at all. All that would happen was that it would start and then shut down and leave an error message. Microsoft, in response to my query suggested to go to the Control panel and then create another mail profile and then open outlook with the new profile so that it will not automatically shut down and then once it is open use that opportunity to import the old .pst file. However in my case since the .pst file was left open when Outlook shut down incorrectly, the file could not be imported saying the file is being used by another process. This option also did not work and then I was advised to use a backup copy of the .pst file which i frtuntely found as a shadow version created becuase of a restore point i had created 12 hrs before the problem occured. Thus i lost a few emails. I think the main reason was that my .pst file is about 7 GB becuase i have emails since 1995. Also I do regular backups, but this is becoming more and more problematic though and takes a long long time.

I juts got this problem. Nothing worked, except finding the file (location is in the error message) and trying to rename it. The system told me it was in use.
I was able to find and kill the processes (Excel and a messenger app) using a file unlocker utility.
I have a feeling this would be just as easily resolved by the stadard 'switch it off and switch it back on again.'

step 1: run the the MSOffice diagnostic tool (that is in programes - microsoft office - tools) and see if this can pick up the problem

if not, usualyy starting outlook should iniciate a scan/repair to your PST file, it will take some time depending on its size.

if all fails, repair outlook by reinstalling it again assuming you have a legal copy

    • You need to archive your mail folders, then export both your mail and archived data into 2 pst files, then back in outlook keep only your most recent emails and delete the rest, 7 GB of PST is enormous and enough to cripple any computer.



      did you try to start outlook in safe mode?


      1. Click Start, point to All Programs, and then point to Microsoft Office.
      2. Press and hold the CTRL key, and then click outlook

      3. export your PST file

      4. close, restart the computer and start outlook normally

      as for the file is being used by another process, it happens so often that there is anther instance of outlook is running even when the main program is not running, you can disable it from task manager in processes tab



      I home any of the above may still help
