Looking for some help with a customers SBS2003 SP2 box, we have inherited this from the previous support guys who didnt have a clue.
Everyone logs in with the same username and password but they all have different mailboxes (i know i know you dont need to tell me). The login they use has access to all mailboxes to send as those mailboxes.
Now the problem, it seems that after some updates were installed and the server rebooted the login account in most cases is not able to send emails from the "email" account any more.
They can receive.
Any email returns an error with "You do not have permissions to send to this recipient, please contact your administrator"
One or two users are able to email but, comparing their group membership, exchange mailbox and AD permissions shows that they are all members of the same groups and have all the same permissions as the ones that dont work.
I need to see exactly why the mail is failing and if possible see the effective permissions of the accounts on the mailbox rather than the supposed applied permissions. Has anyone else ever had this?
