A few users have been trying to access a shared calender with no success. When they try to access the calender they get an error that says "Unable to display the folder. The server mailbox cannot be opened because this address book is not a mail user." I have verified that the public folder exists in "public folders" within exchange system mananger 2003 and everyone has access rights to it.
Anyone have any ideas here?
Another note, I can actually view the calender from within exchange system manager.
