Find and fix issues after adding your domain or DNS records in Office 365

Getting your domain set up to work with Office 365 can be challenging. The DNS system is nitpicky to work with, and the DNS setup for your domain affects important business activities, like email!

Tip   We can help you fix this! See support options.

Can't verify your domain?

There are a couple of common reasons that domain verification doesn't work as it should:

  1. The verification record value isn't quite correct. Doublecheck that you've copied and pasted the exact value into the TXT verification record at your DNS host. One common issue is not including the "MS=" part of the record. We need that too!

  2. The record hasn't been saved. At some DNS hosts, you have to take an extra step to save the zone file (where the DNS record is stored) so that it will updated across the Internet. Make sure you've saved your changes so Office 365 can see and verify the record.

  3. The record hasn't updated across the Internet. It typically only takes a few minutes for us to be able to see the new record, but occasionally it can take as long as a few hours. If you've waited longer than that, and you're sure the record value is correct, please give us a call so we can help sort out whatever's wrong.
