Symptoms

Consider the following scenario:

You have a server that is running Microsoft Exchange Server 2010.
The name of a mailbox database on the server contains one or more of the following special characters:
(
)
:
You install Microsoft Exchange Server 2010 Service Pack 2 (SP2).
The System Attendant homeMDB attribute for a user points to the mailbox database that has special characters in the name.
The user tries to access the Exchange Server 2010 SP2 mailbox.

In this scenario, the MSExchangeServicesAppPool application pool crashes on the Exchange Server 2010 Client Access server (CAS). Therefore, Exchange Web Services (EWS) applications cannot connect to the servers that are running Exchange Server 2010.

Additionally, the following error message is logged in the Application log in Event Viewer on an Exchange Server 2010 Client Access server:
