I have a set of public folders in an Exchange 2003 / Exchange 5.5 environment. All of my user's mailboxes are on the Exchange 2003 server and all of the public folders are on the Exchange 2003 server.
Exchange 20003 is in new_domain. The Exchange 5.5 server is in old_domain.
1/2 of my users login to old_domain
1/2 of my users log in to new_domain
All of the users can access their mailboxes successfully.
The user in the new domain can see the folders fine. The users in the old domain cannot see folders for which they have permissions.
What am I missing?
