We recently migrated our company's email off of a GoDaddy implementation of Office365 and onto a "native" Microsoft one. The transition was relatively straightforward, but afterwards we noticed one odd hitch: we've stopped receiving notification emails from BitBucket. They're not going into Junk Email, and we seem to be getting emails from everyone else - but something has happened with BitBucket's emails.
Any suggestions about what might have gone wrong, and/or how to fix it?
