Where are my mailboxes getting their permission from?


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?

Did you by chance have Exchange 2003 previously?

Try this...

Open up Adsi Edit.
Open Default Naming Context > go the user folder and right click for properties. Check the Security Tab to see if the Account you mentioned has been added there.

Hi Guy,

Sorry for the late response.

I found where this is coming from. It was to do with a Blackberry server that was implemented some time ago. The permissions were set via powershell and in ADUC, the domain permissions had send as ticked. I removed it and new mailboxes now do not get the permissions.

Thanks for the advice though.
