In this video I demonstrate the end user experience during different failure scenarios in a highly available Exchange Server 2010 environment.
The demonstration involves:
- Two connected mailbox users sending email back and forth
- An Exchange 2010 CAS Array consisting of two Client Access servers
- A Database Availability Group consisting of two Mailbox servers

This is driving me crazy.
any help will be appreciated.
