Connect DNS records at Namecheap to Microsoft 365

Add a TXT record for domain ownership verification

Before you can use your domain with Microsoft 365, you need to prove you own the domain. Your ability to sign in to your account at your domain registrar and create the DNS record proves to Microsoft that you own the domain. This process involves creating a TXT record at your domain registrar with a specific value that Microsoft can look for. When Microsoft finds the record with the correct value, your domain is verified. The TXT record is used only to verify that you own your domain. It doesn't affect anything else and can be deleted once domain verification is complete.

To add the TXT record for domain verification at Namecheap, follow these steps:

1. Get the TXT value specific for your domain from the Microsoft 365 admin center. For help on finding the value of your TXT record in the Microsoft 365 admin center, see Gather the information you need to create DNS records.

2. If you're not already signed in to the Namecheap Advanced DNS page for your domain, follow the steps in Sign in to Namecheap to manage your domain's DNS records to get there.

3. In the HOST RECORDS section, select ADD NEW RECORD.

   

4. In the Type drop-down, select TXT Record. The Type drop-down automatically appears when you select ADD NEW RECORD.

   

5. In the boxes for the new record, enter the values from the following table:

   Type	Host	Value	TTL
   TXT	@	MS=msXXXXXXXX	30 min

   • Use the TXT value you gathered earlier from the Microsoft 365 admin center. The value MS=msXXXXXXXX shown in the table is only an example.
   • Choose the TTL value from the drop-down list.

   

6. Select the Save Changes ✅ check mark icon or select the Save All Changes button located just below the record you added.

   

7. Wait a few minutes for the TXT record to propagate before continuing.

Now that the TXT record is added at your domain registrar's site, go back to the Microsoft 365 admin center and complete the domain ownership verification process. When Microsoft 365 finds the correct TXT record, your domain is verified.

To verify the record in the Microsoft 365 admin center, follow these steps:

1. Sign in to the Microsoft 365 admin center.

2. From the left navigation bar, select … Show all, and then select Settings to expand it.

3. Under Settings, select Domains.

4. In the Domains page, select the ellipsis ⋮ next to the domain that you're verifying, and then select Start setup.

   

5. In the Verify you own your domain page, make sure Add a TXT record to the domain's DNS records is selected, and then select Continue.

6. On the Add a record to verify domain ownership page, select Verify.

7. After you verify domain ownership, the How do you want to connect your domain? page appears. The rest of the wizard walks you through adding additional DNS records to connect your domain to Microsoft 365 services.
