Error message in the Operator Console in MOM 2005 when you use MOM 2005 to monitor Exchange Server 2003 or Exchange 2000 Server:

You use Microsoft Operations Manager (MOM) 2005 to monitor a computer that is running Microsoft Exchange Server 2003 or Microsoft Exchange 2000 Server. When you do this, you receive an error message in the Operator Console in MOM 2005. This error message resembles the following error message:

This issue can occur when the mailbox access account does not have the "Send As" user right for the mailbox of the MOM 2005 agent account.

Note The agent account is also known as the test account.

The mailbox access account may have lost the "Send As" user right because of a recent change in how the "Send As" user right is implemented in the different versions of Microsoft Exchange. This issue occurs when you have installed a hotfix that includes this change.

You can verify that you installed a hotfix that includes the change in the "Send As" user right by verifying that one of the following conditions is true:

To resolve this issue, you must grant the mailbox access account the "Send As" user right on the mailbox of the MOM 2005 agent account. The agent account is typically named "Server_Name_MOM."

Only the MOM 2005 agent mailbox for the first mailbox store actually sends mail flow script messages. Therefore, you must assign the "Send As" user right to the mailbox access account on only the mailbox of the agent account in the first mailbox store. Do this on each Exchange server that runs mailbox scripts.

To do this, follow these steps on the domain controller that hosts the MOM 2005 agent user account:

1.	Start the Active Directory Users and Computers management console.
2.	On the View menu, click Advanced Features to enable the Security page for user accounts.
3.	In the left pane, click the container that contains the MOM 2005 agent user account.
4.	In the right pane, right-click the MOM 2005 agent user account, and then click Properties. Typically, the MOM 2005 agent user account is named "Server_Name_MOM."
5.	Click the Security tab, and then click Add.
6.	In the Look in box, click the appropriate object.
7.	In the list of user accounts, click the MAA user account, click Add, and then click OK.
8.	In the Permissions box, click to select the check box under the Allow column for the "Send As" permission.
9.	Click OK.
10.	Exit the Active Directory Users and Computers management console.
11.	Wait about 15 minutes for the Exchange store to update its permissions cache and to make the new permissions effective.
