How to Disable Unified Messaging for a User
Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
Applies to: Exchange Server 2007, Exchange Server 2007 SP1, Exchange Server 2007 SP2, Exchange Server 2007 SP3
This topic explains how to use the Exchange Management Console and the Exchange Management Shell to disable Unified Messaging (UM) for an Exchange 2007 recipient. When you disable a user for Unified Messaging, the user will no longer be able to use the UM capabilities found in Microsoft Exchange Server 2007. If you prefer, you can keep the UM settings for the user after the user is disabled.
After you disable Unified Messaging for a user, the user's account may still be listed when a caller performs a directory search by using a UM auto attendant menu or by using Outlook Voice Access. The caller may be able to locate a user in the directory, but when they try to contact the user, they will be taken back to the main menu in Unified Messaging. This may cause callers to become frustrated with the system. You can prevent callers from using a directory search to contact the user who was disabled by connecting the user to another voice mail system, removing the user from the UM auto attendant directory search, or by removing the user's account from the Active Directory directory service.
After a UM-enabled user account is disabled for Unified Messaging, the user may still have access to their individual UM-enabled mailbox by using Outlook Voice Access or Outlook. This can occur when all domain controllers in the Active Directory directory service have not fully replicated all changes to objects to the Active Directory database. To lessen the risk of a user gaining access to their mailbox even though their account has been disabled for Unified Messaging, you can manually force Active Directory replication to occur or remove all UM information from the user's mailbox when the user is disabled for Unified Messaging.
Before You Begin
To perform this procedure, the account you use must be delegated the Exchange Recipient Administrators role.
For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.
Also, before you perform these procedures, confirm the following:
The existing Exchange 2007 recipient has an Exchange 2007 mailbox.
The existing Exchange 2007 recipient is currently enabled for UM.
A UM dial plan has been created.
A UM IP gateway has been created.
To use the Exchange Management Console to disable Unified Messaging for a user
In the console root of the Exchange Management Console, expand the Recipient Configuration node.
In the result pane, select the user whose mailbox you want to disable for Unified Messaging.
In the action pane, click Disable Unified Messaging.
In the confirmation dialog box, click Yes to confirm that Unified Messaging will be disabled for the user.
To use the Exchange Management Shell to disable Unified Messaging for a user
