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 &quot;Full Mailbox Access&quot; permissions for a user's mailbox to another user. You do not grant &quot;Send As&quot; or &quot;Send On Behalf Of&quot; 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.
