We want to join a new server with Exchange Mailbox 2010 role (MBX) to existing Database Availability Group (DAG) that is already registered in OA. How we can do this?
It can be done in the following way:
- Deploy a new Exchange Mailbox Server
- Add the newly created Exchange Mailbox Server to a desired DAG
- Install OA Agent on that server
Necessary instructions can be found in OA Hosted Exchange Deployment Guide.
Please also refer to native Exchange documentation pages in case of any questions at steps 1 and 2.
