Add Domain Name in Office 365

After you sign up for Office 365, the very first thing you would want to do is add a domain name. Make sure you own the domain name, otherwise you can’t add the domain name. You will be stuck at verification page. In this post, I will show steps to add domain name in Office 365.

Add Domain Name in Office 365

Log on to Office 365. Go to Office 365 Admin Center.

Add Domain Name in Office 365

Click DOMAINS in the features pane. Click Add domain option as shown above.

Click Next on get started page.

Add Domain Name in Office 365

Type your domain name that you want to add as shown above. Click Next.

verify domain name (1)

You now have to verify that you actually own the domain name. You can use MX or TXT record for verification. I recommend to use TXT record as MX record modification can affect mail flow. Remember, if you don’t own the domain name, then you can’t add in Office 365. Go to your domain hosting panel. Create a TXT record and add the TXT value as shown above.

Add TXT Record

It might take 1 minute to 24 hours for the TXT record to replicate to all public DNS servers on the Internet. So wait for about at least 5 minutes before clicking next button. Click Next on Office 365 domain verification page.
