Another user can create and send meeting requests on behalf of a mailbox owner even though "Send As" and "Send On Behalf Of" permissions were not granted in Exchange Server 2003 (921539)


The information in this article applies to:

  • Microsoft Exchange Server 2003 Service Pack 2

SYMPTOMS

Consider the following scenario. On the Exchange Advanced tab in the Active Directory Users and Computers snap-in in Microsoft Exchange Server 2003, you grant "Full Mailbox Access" permissions for a user's mailbox to another user. You do not grant "Send As" or "Send On Behalf Of" permissions. Therefore, you expect that the other user cannot send e-mail messages or meeting requests on behalf of the mailbox owner.

In this scenario, the other user can access the mailbox as expected. The other user cannot send e-mail messages on behalf of the mailbox owner as expected. However, the other user can create meeting requests and send meeting request e-mail messages on behalf of the mailbox owner.
