I looked a bit and didn't find another thread about this - so sorry if I missed its existence MODs.

So I had upgraded a machine from Office 2000 to Office 2010. When upgrading Outlook I was able to import pretty much everything from the existing installations of Outlook (used for organizing, scheduling, contacts etc) and Outlook Express (used for email). Now in addition to the usual email contacts, there were also 3 other address books. SAY for example something like this:

> email accounts
Contacts - [emailprotected]
VENDORS - Outlook Data File
Clients - Outlook Data File
Contacts - Outlook Data File

One day - POOF! The contacts for the Outlook Data File entries were just gone. Not only was Contacts - Outlook Data File blank, but Vendors and Clients was outright gone!

Anyway, I've CHECKED every .pst I can find, and none of them seem to contain these address books... so any ideas? They were not found in any of Deleted Items or Trash folders... and I haven't been able to find them anywhere... It's quite perplexing...

So yeah... if you have any advice on things to check it's much APPRECIATED - if not I can do a system restore and see what I can find.

Thanks in advance!!
