I have been doing a lot of Exchange on-prem to Exchange Online migrations over the last few years, because of that I use mxtoolbox.com a lot for querying MX, SPF, DMARC, and DKIM records.

Currently working on rebuilding a failed Exchange 2016 DAG node, installing Exchange, and getting the databases in sync again...
