We have a user using Outlook 2000 to access their mail account on an Exchange 2000 server. The user has access to all the public folders, most of which are public calendars. There are three of these calendars that when this user tries to access it appears blank to them, and when they try to post to it no matter what time slot on the calendar they choose it posts to the current time of day. The user is set with author permissions to these folders, and I have tried to add and remove her from it without any change. I have accessed the users account from different workstations with the same result. Any ideas on where to start to troubleshoot this?
