There are 6 users who are supposed to be editors of a calendar that was created in another users Exchange mailbox (server is 5.5).
They are all using Outlook2000.
They have all added the one users mailbox in the “open additional mail boxes” properties on the advanced tab for the Exchange Server in their profile.
4 of the 6 have no problem. The other 2 get the unable to expand folder when they try to access the users mailbox.
All of the mailboxes are on the same server.
