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. By default, the Microsoft Exchange Unified Messaging service is started after the Unified Messaging server role is installed on a computer running Microsoft Exchange Server 2010. However, there may be times when you must restart the Microsoft Exchange Unified Messaging service manually, for example, when you've taken the Unified Messaging server offline and have to bring it back online.

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

Note:
The default startup time for the Microsoft Exchange Unified Messaging service is 120 seconds. You can increase this time-out value by editing the Msexchangeum.config file located in the \Program Files\Microsoft Exchange\V14\bin folder.
