When you restore Microsoft Outlook Personal Folder (PST) files, the following differences will exist between the restored PST and the original PST:
Any rule that points to a folder inside a PST file will no longer work. You must edit the rule to point to the correct folder.
Restored PST files will have Inbox, Outbox, and Sent Items folders, even if the original files did not have them.
If you use a password for your PST file, you must reset the password after restoring your PST file.
