I have a network with a 2003 server DC, exchange on a 2003 server (not DC), a few other servers, one domain.
I have a few mailboxes created that a couple of people need access to. Everything usually works fine.
I just created one mailbox and a security group. As far as I know they're the same as all the others I've created before. I've given full access to the mailbox to that security group and it doesn't work. I had all users log off and still nada. If I add the user directly in the mailbox access rights, it works right away.
The security group itself is mailbox enabled and everything seems ok, I just don't get why it's not working. I'm sure it's stupid I'm just not seeing it.
