For those waiting for the Data Protection for Exchange mailbox restore (IMR) fix for Exchange 2010 with SP3... ... it's ready!
http://www.ibm.com/support/docview.wss?uid=swg24034995 Note: Until the FlashCopy Manager for Microsoft Exchange 3.2.1 fix is available, FlashCopy Manager customers may install and use the Data Protection for Exchange 6.4.0.2 interim fix in their environment. The Data Protection for Microsoft Exchange fix provides equivalent functionality to FlashCopy Manager for Microsoft Exchange when used in FlashCopy Manager environments. Thanks, Del
