We have exchange 2007. When we create new mailboxes, it automatically assigns full access permission to another account. I don't know where this is coming from.
The account was deleted and then recreated with the same name. This has resulted in mailbox permissions just having an entry for the SID.
My question is where are may mailboxes getting their inherited permission from? How is it happening? The permission is applied to ANY mailbox I create. How can I change it to stop applying those settings and apply the ones for the new account?
