Exchange2000::SendAs Permission

From MS KB
This step-by-step article describes two methods in Exchange 2000 Server that you can use to configure a mailbox so that users other than the mailbox owner can use that mailbox to send messages.



In Exchange 2000 Server, you can permit one or more users to send messages on behalf of a particular mailbox owner by granting "Send on behalf" permissions. You can also permit one or more users to send messages as a particular mailbox owner by granting "Send As" permissions.

Grant "Send on Behalf" Permissions

If you grant a user "Send on behalf" permissions for another user's mailbox, that user can send mail on behalf of the mailbox owner. The name in the From box of these messages appears as

From: DelegateUser on behalf of MailboxOwner

where DelegateUser is the name of the user to whom you granted "Send on behalf" permissions and where MailboxOwner is the name of the user who owns the mailbox.



To grant a user "Send on behalf" permissions for another user's mailbox:

1. Click Start, point to All Programs, point to Administrative Tools, and then click Active Directory Users and Computers.
2. In the console tree, click Users.
3. In the right pane, right-click the mailbox of MailboxOwner, and then click Properties.
4. Click the Exchange General tab, and then click Delivery Options.
5. Under Send on behalf, click Add.
6. Type the name of the DelegateUser, click Check Names to verify the name, and then click OK.
7. Click OK, and then click OK.
8. Quit Active Directory Users and Computers.

For example, if you grant UserB "Send on behalf" permissions for UserA's mailbox, UserB can send messages on behalf of UserA. The From box in these messages appears as follows:

From: UserB on behalf of UserA

Grant "Send As" Permissions

If you grant a user "Send As" permissions for another user's mailbox, the DelegateUser can send mail as the MailboxOwner. The From box in these messages appears as follows:

From: MailboxOwner

To grant a user "Send As" permissions for another user's mailbox:

1. Click Start, point to All Programs, point to Administrative Tools, and then click Active Directory Users and Computers.
2. On the View menu, click to select Advanced Features.
3. In the console tree, click Users.
4. In the right pane, right-click the mailbox of MailboxOwner, and then click Properties.
5. Click the Security tab.
6. Click Add, and then type the name of the DelegateUser.
7. Click Check Names to verify the name, and then click OK.
8. Verify that DelegateUser is selected, and then click to select the Allow check box next to Send As in the Permissions list.
9. Quit Active Directory Users and Computers.

For example, if you grant UserB "Send As" permissions for UserA's mailbox, UserB can send messages that appear to be sent from UserA. The From box in these messages appears as follows:

From: UserA
