Consider the following scenario:
- You enable Archiving on the front-end server in Microsoft Office Communications Server 2007 R2, and then you select the Shut down server if archiving fails option.
- The archiving service stops on the archiving server.
- The front-end services are still running before the critical mode timer causes the services to stop.
- Office Communicator clients that are enabled for archiving send messages between the time when the archiving service stops and the time when the front-end services stop.
This issue occurs if the failure time of the archiving service is greater than the value of the ReachQueue timer, which is used for critical mode archiving.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
