If OVH is your DNS hosting provider, follow the steps in this article to verify your domain and set up DNS records for email, Skype for Business Online, and so on.
After you add these records at OVH, your domain will be set up to work with Microsoft services.

Global Administrator is a highly privileged role that should be limited to emergency scenarios when you can't use an existing role. For more information, see About administrator roles in the Microsoft 365 admin center.

Add a TXT record for verification
Before you use your domain with Microsoft, we have to make sure that you own it. Your ability to log in to your account at your domain registrar and create the DNS record proves to Microsoft that you own the domain.
Note
This record is used only to verify that you own your domain; it doesn't affect anything else. You can delete it later, if you like.
To get started, go to your domains page in OVH by using this link. You'll be prompted to log in.
On the dashboard landing page, under View all my activity, select the name of the domain that you want edit.
Select DNS zone.
Select Add an entry.
Select TXT
In the boxes for the new record, type or copy and paste the values from the following table. To assign a TTL value, choose Custom from the drop-down list, and then type the value in the text box.
Record type Sub-domain TTL Value TXT (leave blank) 3600 (seconds) MS=msxxxxxxxx
Note: This is an example. Use your specific Destination or Points to Address value here, from the table. How do I find this?Select Next.
Select Confirm.
Wait a few minutes before you continue, so that the record you just created can update across the Internet.
Now that you've added the record at your domain registrar's site, you'll go back to Microsoft and request the record. When Microsoft finds the correct TXT record, your domain is verified.
To verify the record in Microsoft 365:
In the admin center, go to the Settings > Domains.
On the Domains page, select the domain that you're verifying, and select Start setup.
Select Continue.
On the Verify domain page, select Verify.

Add a TXT record for SPF to help prevent email spam
Important
You cannot have more than one TXT record for SPF for a domain. If your domain has more than one SPF record, you'll get email errors, as well as delivery and spam classification issues. If you already have an SPF record for your domain, don't create a new one for Microsoft. Instead, add the required Microsoft values to the current record so that you have a single SPF record that includes both sets of values.
To get started, go to your domains page in OVH by using this link. You'll be prompted to log in.
On the dashboard landing page, under View all my activity, select the name of the domain that you want edit.
