Restoring a Database Availability Group Copy

The Exchange Server 2010 Writer does not support restoring data directly into a database copy that participates in a Database Availability Group. The only supported situation in which backup data can be used to recreate a database copy is when all passive and active copies of the database must be reconstructed from the same backup data. Using different backup data for individual copies, or not restoring all copies is unsupported, and may result in the database being unmountable.
