This DAG seems extremely flaky and problematic and poorly designed. It is such a shame as it seems like a good idea in theory.

@Jack:
I'm sorry that you feel that way. There's an abundance of evidence to the contrary though...
Maybe you should consider a support case to help work through some of the issues that you have been experiencing.

A support case with who? Microsoft? I don't have a time to be calling microsoft every time the DAG decides to come up with a new problem.
I would be interested in some of that evidence because i find that microsoft likes to convince itself that it creates better software than it actually does.

@Jack:
I guess I can only speak from experience and the multitude of successful installations that i see (including those that actually service Office 365 for example).
We're always here to help - and you can contact me directly through my blog should you desire - if there is some constructive assistance we can provide.

I appreciate your efforts and without people like you making blogs, I don't know how a lot of these MS products would ever function properly. As a lot of these sort of "fixes" are not in the microsoft training nor available in official documentation. I
have experienced similar problems with SCCM, WDS/MDT, DFS and so on..

I have a DAG with two servers and one witness server. When I run Get-DatabaseAvailabilityGroup -Identity XXXXX -status | fl on the Primary Active Manager server the results reports the Witnessshareinuse as Primary but when ran on the other the Witnessshareinuse is empty. Is this correct?

Hi Tim,
Can we have FSW on a Mailbox server which is a part of a DAG?
What impact will it have if I have 11 member servers in a DAG?
Since its an odd number of nodes It wont need an FSW but what if one node goes down, what will be the possible impact?

The requirements for the witness server are as follows:
•The witness server can't be a member of the DAG.
•The witness server must be in the same Active Directory forest as the DAG.
•The witness server must be running Windows Server 2012, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003 R2, or Windows Server 2003.
•A single server can serve as a witness for multiple DAGs. However, each DAG requires its own witness directory.
========================
An odd number of nodes does not have a file share witness configured in cluster.

An odd number of nodes does not have a file share witness configured in cluster, and will not have one automatically configured if the vote count becomes even because a node went down.
