I've been having some problems with DNS lately. My email domain isn't being recognized, and it's throwing errors about DNS not found. Everything is paid for and seems to be set up correctly on my end, so I'm wondering if anyone else is facing similar issues?

I'm facing the same problem. Interestingly, an email I sent to 95 internal users went through without a hitch, so it's a bit odd.
Yeah, I'm seeing similar issues. Internal users can't send emails to each other on Exchange Online, and we're getting messages that say the recipient's domain doesn't exist.
We had similar issues this morning starting around 6 AM PST. By 8 AM, everything seemed to fix itself. I didn't touch any settings, so it might've been a global DNS issue.
Are you using a Connector in Exchange for security or signatures? We're having trouble getting bounce backs to look up CodeTwo.
Yep, we use CodeTwo and it's causing issues on our end.
We're using CodeTwo too, but it's been operating fine for us. Not completely down yet.
I just tried accessing smtp.codetwo.online, and it says that it doesn't exist.
Yup, that's exactly what's happening to us too.
