Start the Microsoft Exchange Unified Messaging service


Applies to: Exchange Server 2013

Topic Last Modified: 2012-11-16

You can use the Services snap-in in Microsoft Management Console (MMC) or cmd.exe at a command prompt to start the Microsoft Exchange Unified Messaging service on a Mailbox server. By default, the Microsoft Exchange Unified Messaging service is started after a Mailbox server is installed. However, there may be times when you have to restart the Microsoft Exchange Unified Messaging service manually, for example, when you've taken the Mailbox server offline and have to bring it back online.

When the Microsoft Exchange Unified Messaging service is started on a Mailbox server, the Mailbox server is available to answer and process incoming UM calls.

For additional management tasks related to Mailbox servers, see UM services procedures.

  • Estimated time to complete: Less than 1 minute.

  • To perform the following procedures, you must log on to the Mailbox server by using an account that's a member of the local Administrators group.

  • Verify that the Mailbox server is installed, either on the same computer as the Client Access server or on a separate computer.

  • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard shortcuts in the Exchange admin center.
