I am the administrator and changed my PC's name because my password would not let me logon correctly. When I finally logged on to my PC the desktop was completely gone. Microsoft Outlook Address Book is gone. I have about 300 e-mail address I need to recover. I had to remap to my server drives. I know this whole thing seems brainless. I finally after a whole day restored my desktop back but my Address Book is no where to be found. I looked for the .PST files but they are not present. I hope this is not a lost cause. This whole thing was caused because of the password issue. When I sent Outlook to my desktop I realized I had a serious problem. I would appreciate any help.
