Hi Experts,
I have three exchange servers which were configured as a DAG, each one contains a database UserDB01, totally three copys, but when i created the protection group to protect UserDB01, only two servers show up under the database, really confused where the other one goes, beacause i have installed the agent on each server successfully and when i went to Exchange server and run get-DatabaseAvailableGroup xxx， it will list all three servers.
