Hi there, I understand you looking to implement Exchange Server 2019 with a Database Availability Group stretched over 2 sites ? This is something I can do for you and begin as soon as you want. I have worked with Microsoft Exchange Server since its beginning and have have designed, implemented and managed each version right up to 2019 with special emphasis on the full exploitation of its business continuity features such as DAGs. I would love the opportunity to use my experience and knowledge to help you out.
If you have any queries then please get in touch
Cheers,
Robert R
