I added our help desk to the Exchange 2007 Recipient Admin group. However, the issue they are running into is that they can't add users to mailboxes. (Example: Help desk mail box, and they want to add all the help desk staff to it). They also can't add or change the email address of a mailbox. What permissions do I need to change for them to complete these tasks? Thanks

Hi, According to following article: http://technet.microsoft.com/en-us/library/aa996881(EXCHG.80).aspx The Exchange Recipient Administrators role has permissions to modify any Exchange property on an Active Directory user, contact, group, dynamic distribution list, or public folder object. Members of the Exchange Organization Recipient Administrators role have the following permissions: Read access to all the Domain User containers in Active Directory that have had Setup /PrepareDomain run in those domains. Write access to all the Exchange specific attributes on the Domain User containers in Active Directory that have had Setup /PrepareDomain run in those domains. Membership in the Exchange View-Only Administrator role. Based on my test on the lab, I am able to modify Email Address of Mailbox Enabled user and Mailbox Enable existed AD user after adding a user to Recipient Admin group. Nevertheless, the user does not have permission to create a new mailbox enabled user. ~~~~~~~~~~~~~~~~ Mike Shen TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com ~~~~~~~~~~~~~~~~
