My outlook 2007 (on Windows 7 64 bit) worked fine for two weeks. I then installed a printer/scanner/copier and the Outlook Window wouldn't open. I went to Microsoft's website and found a page that said my registry key was damaged. The page had a link to a Fix It program. I ran the program and it looks like all my Outlook data was wiped out.

Can I get the data back?

For future reference, how should I protect myself if the key goes bad again?

Do you think I should unistall Outlook and re-install?

Can you try to keep Outlook installed but delete all Outlook's profile and configure a new one. Then, try again. – r0ca Feb 9 '10 at 1:14

I think that Outlook might have forgotten (i.e. overwritten) the location details about where your pst(the data files) were located.

Just do a global search (in non-indexed parts also) of all your drives with the search file keyword as '*.pst'.

If you find them, just backup them & using this post, try restoring them back.

Also a post which will help you backup your data files.

Well first you want to try and determine if you data is actually still available. Outlook 2007 stores the bulk of a users data in a file type called PST.

Here is detailed blog post with detailed information on it's location : here

Here is the short version:

  • Open Control Pannel and select the "Mail" Icon Select the Data Files Tab
  • Take Note the location of the PST file.
  • Browse to this location and see if you find any PST files

Ideally you want one that says Outlook.PST as this is most probably your active email. If you do not see an outlook.PST you may be correct in that your data may have been purged. If this is the case you will probably need to run some sort of data scanvenger / recovery utility such as R-Studio. If you see a file named archive.PST in the same location, this is most probably older email and not your active data. If you do find an Outlook.PST file you should be able to go into Outlook and select file and then open "Outlook Data File".

Caveat: Make sure you go into Windows Explorer, tools and options and check that you are showing all files and folders. The folder location that Outlook stores its PST files is hidden by default.

Im not sure what you can do to protect yourself from future registry key corruption other than be cautious. You can re-install Outlook but I would advise strongly in trying to determine if you data is still there prior to doing a re-install. If it has been purged you will want to run a data recovery program as soon as possible and cease using the computer until you do. Continued use will almost certaintly make data recovery a problem.
