Hello. I want to ask a question regarding Mailbox quota alteration for Exchange Recipient Administrator in Exchange 2007 SP1. By default, Exchange 2007 allow Exchange Recipient Administrator to modify the mailbox quota in Exchange 2007 SP1. I've already view all the attributes in ADSIEdit.msc and the result is negative. Just really want to know about the method to do it because i am not familiar enough with Exchange 2007 SP1. Thanks a lot. Regards M.A.Ezwadi AzizCEKPIK

Hi M.A.Ezwadi, It is ture you can modify granular permission for the admin, but ACLs created several challenges in Exchange 2007, such as modifying ACLs without causing unintended consequences, maintaining ACL modifications through upgrades, and troubleshooting problems that occurred due to using ACLs in a nonstandard way. So if possible, I would suggest you upgrade to Exchange 2010, it is much easier to do it.
