I recently upgraded from32 bit XP Pro to 64 bit Windows 7, and am having problems restoring my E-mail accounts.
Before changing over I backed up (copied onto an external HDD) all my data files and have copied everything back over, with the exception of my Outlook file.

When I reinstalled Outlook, via MS Office Enterprise 2007, I changed the location of its data file so that it could open my Outlook.pst files but I am getting the message "The file G:\outlook.pst is not a personal folders file"

I also tried to import using the "Import/Export" menu but get the same message

Does anyone know how I can get my e-mail a/c's back?

Cheers
