Was a little careless today with helping someone transfer their GoDaddy domain and O365 mail to a new server (transferring their nameserver). When I looked at the GoDaddy domain DNS log, I saw all these entries that looked related to O365. I thought when I move the domain nameserver that those DNS entries relating to O365 would stay so I didn’t even save the info. Boy was I wrong, after I changed the nameserver I saw all the entries disappear.
Took me a little while to figure out how to setup the DNS entries needed. Not sure why but it took me awhile to find the instructions on GoDaddy. But eventually, I got it going but felt pretty bad that I probably prevented emails from being received.
Definitely, a lesson learned. Need to be more careful in the future.
