I received two different emails that want me to update my Office 365 MX records. One mentions that the update has to be completed until June 2014, the other one talks about January 2014. Both emails are linking to (different) documents that talk about generic MX records which are only supported until January 2013!
2013? I have never used generic MX records. Quite confusing!
Can someone please clarify which date is correct, what kind of MX records are no longer supported and how the new ones look like.
