New IT Network Admin needs help with O365 DNS records TXT error so we can sync AD's


  • So we have just gotten a new Network Admin (Im the SharePoint dev) and he is not familiar with O365 and their setup. He mentioned that it is different setting up the O365 DNS than local (?) as we are getting an error when trying to do the DirectSync of our Local to O365 Active Directory. It says the TXT DNS record is incorrect and from what he has found it is supposed to be 2 records but there are 3. I probably sound like an idiot here and am as I really don't know much of anything about Exchange or too much about DNS records to begin with but MS support hasn't gotten back to us in 2 days since the ticket has been entered and we cant sync the AD's to get him his email properly setup! We've gone through the Technet and other docs with no success yet.

    Thanks in advanced for any help!



    Thanks and Best Regards, Keith Wagenknight

  • There are a whole lot of things (that are unrelated) here in the thread.

    What services are you attempting to use in Office 365?  Office 365 is comprised of a number of services, including Exchange (email), SharePoint, Yammer, Skype for Business, and many more.  In order to verify a domain in Office 365 (such as using your existing purchased domain name), you need to go through the process to register the domain with Office 365, which generates a TXT record that you place in external DNS. You confirm it through the Office 365 portal, and that gives Office 365 the ability to use that domain on your behalf.

    Depending on which services you want to use from Office 365, you may need to enter additional records (CNAME, SIP, SRV, etc) to allow both Office 365 and your client applications to perform discovery and locate the services we are providing.
