"Send As" permission behavior change in Exchange 2003 (895949)



The information in this article applies to:

  • Microsoft Exchange Server 2003 Enterprise Edition
  • Microsoft Exchange Server 2003 Standard Edition

SYMPTOMS

A fix has been released that changes the behavior of the "Send As" feature in Microsoft Exchange Server 2003. Prior to this change, any user with the "Full Mailbox Access" permission for a mailbox also had the ability to "Send As" the mailbox owner.

CAUSE

The "Send As" permission has been implicitly included in the "Full Mailbox Access" permission. By customer request, this behavior has now been changed to allow granting "Full Mailbox Access" without having to also allow "Send As."

This change is implemented in the following versions of Exchange Server 2003:
  • Microsoft Exchange Server 2003 Service Pack 1 with a Store.exe file version of 7233.51 or higher
  • Microsoft Exchange Server 2003 Service Pack 2 with a Store.exe file version of 7650.23 or higher
This change is not included with Exchange Server 2003 Service Pack 2. If you have been running the Exchange Server 2003 Service Pack 1 version of Store.exe that includes this change, and you upgrade to Exchange Server 2003 Service Pack 2, you must install the Service Pack 2 version of this hotfix to retain the new behavior. This change will be included in Microsoft Exchange Server 2003 Service Pack 3.

An update for Microsoft Exchange 2000 Server is available from the following Microsoft Knowledge Base article:

915358 A hotfix is available to change the behavior of the Full Mailbox Access permission in Exchange 2000 Server

MORE INFORMATION

There are three exceptions to the new "Send As" behavior for:
  • A mailbox owner
  • The associated external account for a mailbox
  • A delegate of the mailbox owner
If any of the above three accounts have "Full Mailbox Access" permission, they can send as the owner without explicit Send As permission. A mailbox owner and the associated external account both have "Full Mailbox Access" permission by default, while delegate accounts do not.
