I have a client with a very customized setup. They have an SBS 2003 server that is sending from multiple domains in Exchange. To accomplish this, I added the domains to the receipient policy, created usernames for the additional domains and added as additional mailboxes to the each of the users Outlook clients. This was working great. The users were able to send and receive from multiple domains without a hitch.
The problem is that the server crashed while we were performing maintenance on the backup. We were able to recover their data partition but we could not recover the operating system partition. We had to re-install SBS 2003 and setup this painful e-mail configuration. I was able to get two of the domains to work but now I am having some strange issues with setting mailbox rights and removing users.
Somehow the users are inheriting permissions from somewhere that is blocking me from making changes to mailbox rights for the additional users. The checkboxes in active directory are grayed out. I am also having issues removing and adding users to the server level of the system manager. I cannot remove "everyone" permission because the server level is inheriting permissions from somewhere that I cannot find.
I've attached two screenshots with each of the issues I am having trouble with. Ultimately, I want to be able to edit their mailbox rights from Active directory and also remove users from the server level of Exchange in system manager.
I have downloaded and installed ADSIedit but I am not too familiar. I've turned off inheritance on in ADSI and it brought the Exchange store down. I re-enabled that and I was able to mount the store again. It seems like the permissions I've really goofed up the permissions on the server.
