We are a Microsoft partner and have seen this happen several times for multiple customers. I believe it is related to running the setup wizard again where it wipes out and resets all DNS records. It should definitely KEEP any custom records during this process. I am working on the issue again this morning. With the last customer, we moved them back to GoDaddy DNS hosting so it won't happen again. I also noticed you cannot add any custom SRV records to the 365 DNS. 

 

Just be careful clicking the "DNS Management" option when working with a domain. While it seems like this is where you should go to manage DNS, it takes you back through the setup wizard for a domain that is already in the "Setup Complete" status.

Just for reference we went through all the possibilities and the setup wizard wasn't the problem. According to Microsoft they resolved this issue but it proved not to be the case with us. It was also never publicly noted so there's record of what was wrong or what was fixed.
