This moring I granted my supervisor access to my public calendar and task folder. After realizing I made a mistake on my calendar, I deleted the calendar and recopied it. After rebooting the computer, and I when I try to open Outlook 2000, I get the follow error message. Unable to open your default email folders. You do not have permission to log on. I checked all the articles that Microsoft list but couldn't find anything. Please let me know if there is anything else I can try. Is my message store possibly gone or corrupted.
