Exchange 2013 DAG is appearing as Node Majority instead of Node and File Share Majority

Hi,

We have Exchange 2013 SP1 8 mailbox servers single DAG.  Everything looks fine no error but when I check "Quorum Configuration" it only shows Node Majority.  I did follow all the steps when I was setting up DAG earlier this year not sure when it got changed from Node and File Share Majority to only Node Majority.

I checked Get-Databaseavailabilitygroup | Fl and it shows witness server and witness directory.  But Get-ClusterQuorum only shows "Node Majority".

I have checked all the settings and Exchange Trusted Subsystem group is also there.  Witness server is not Exchange Server.

How can I change it to Node and File Share Majority?

Thanks,

Raman
