DNSSEC and Mail

Hi,

We have a Exchange hybrid setup in our environment. Will there be any issues or anything that we should consider of, before we activate DNSSEC for our mail/public domain?

Thanks.

Well, its technically not supported in Exchange Online yet:

You can verify that your hybrid connector supports EDNS which is required for DNSSEC:
