SRV record conflict between on-prem SfB server and Teams

Hi Newlife ,

Not a direct answer to your specific query but I am concerned by the reason of using SfB on prem over Teams.

I would argue that Microsoft would be able to secure any infrastructure better than any single business but that is subjective I suppose.

Back to the DNS point, I can only recommend that you follow official Microsoft guidance. As to be honest if you are wanting to make use of On Prem and Cloud technologies that is 100% the reason for Hybrid deployment options and to do otherwise, working or not, is going to probably be unsupported and a big business risk because of it.
