Very strange issue here. Win 7 64-bit running Office 2010 all updates installed. I am attempting to open a PST archive file and it does not work.
If I go to File -> Open -> Outlook Data File, nothing happens. No browse window opens, no error message pops up.
If I go to File -> Account Settings -> Data Files tab and click Add, I receive the message "The requested operation failed". I get this same error message if Outlook is closed and I am trying to add the data file through the control panel mail applet.
This happens in any profile I create in Outlook. I have tried creating POP and Exchange profiles, and neither one will open another PST file. I have checked the compatibility tab and there are no boxes checked. I have run ALL windows and office updates. I have done a full scan of the system using 3 AV utilities and it is clean. I have also done a repair on Office 2010.
Has anyone seen this before or have any ideas? Any suggestions would be greatly appreciated!
