Microsoft's description

We are adding inbound support for SMTP DANE with DNSSEC to Exchange Online GCC-H and DoD. Look for another roadmap item for inbound support in WW and GCC, and one for outbound support of SMTP DANE with DNSSEC. This item is no longer accurate and is being removed from the roadmap. We apologize for the inconvenience.
