I have two PCswith win XP sp2 and office 2007SP2. On one of the PC I did some thing which I do not remember but in Outlook I can no loger display anthoer mailbox. I have another PC which has win 2000 and office 2000 which is fine and I can add the mailbox or open it from file menu with no problem. It is only on this PC that I can not do this. I uninstalled the office, remove all the profiles, created new profile and still not able to view the folder.
