To try to make a long story short......
I have a computer running Windows XP with SP2.
This computer has 2 users assigned, both are administrative). Let's call them "User A" and "User B".
For some reason, don't ask me why, my sister wanted to merge the files of the two user groups. On someone else's advice, she logged into the User A account.
She opened "C" then "Documents and Settings" and clicked to open the folder for User B. She then selected all, hit copy, and then pasted into User A's folder.
Among a few small problems, which I've already delt with, what happened is.....
Both users have Microsoft Outlook 2003. Both Outlook's are set up with both personal & work email, contacts, etc.
What happened, is the Outlook.pst file for User B was coppied over the Outlook.pst file in User A's account. Now, whichever account you log into, Outlook opens using User B's pst file.
Is there anyway to go back and undo this?
I have already tried System Restore, and although this worked on other files, it did nothing to change the pst file back.
