I have not seen the mail, but the first thing to check is if the sender address seems legit. That is, the address should be microsoft.com and nothing else. If there are any links in the mail, check these as well by hovering over them.
If sender and/or links are suspicious, just delete it. It's likely to be some phishing attempt.
If the mail seems legit... Again, I have not seen it, but if you are not using Azure, I would just ignore it and move on. Even more so if you got this in your private mailbox.
