MS Exchange 2019 Redundancy

[Island3r]

Hi Everyone..

I have a customer who would like to use on prem Exchange 2019 but also have redundancy/high resilience in case that server failed.

They have around 100 mailboxes / 70 Active Directory users. We have two identical servers with decent spec capable of running Exchange 2019.

The existing environment has two Server 2019 DC's and another Server 2019 member server running a few different network applications.

My question is how would you go about achieving this?

Would you have the two servers configured as DAGs and use one of the DC's and the witness server or is there another way?

Any input would be greatly appreciated, thanks

We did both in a DAG and had a random SQL server be the witness. Didnt have to be a DC.
