Office 365: Not sure if your vanity domain is being used by another Office 365 tenant? Don’t worry.

I remember not long ago, the pain of trying to find out in which Office 365 tenant your vanity domain was validated, when you bumped into the error stating that the domain was in use, while adding it to your current tenant.

This was maybe because I work with multiple tenants and I recycle my tenants quite often, for testing purposes, but I’ve also seen it with others while trying to assist them in their migration projects.

Fortunately Microsoft now is very clear in the error message you’ll see, when trying to add a domain to a tenant, that is in use. This is what you will see now:

As you can see above, it will tell you exactly in which tenant the domain is, just so you can login to it and remove it.

Now is there a catch with this? Of course!! Microsoft won’t give you such privileged information, until you enter a valid DNS record for the domain validation. You’ll see something similar to this, if the domain validation is not done properly:

So remember to add the DNS record first and click “Verify”, Microsoft will either add the domain or explain exactly why they can’t, which I am sure it was for a long time one of the main asks of Office 365 admins and consultants.

Office 365 tips: Automatic DNS records creation when your custom domain is hosted with GoDaddy

Last week I started another Office 365 project. The custom domain to validate is hosted with GoDaddy, so once more I took advantage of the excellent integration feature between Office 365 and GoDaddy.

This feature is not new, but it’s very good and therefore always worth blogging about it.

Click here to see the official statement from Microsoft, about this integration, and a demo video.

Now a quick walkthrough. My domain was already validated, but you can use the integration also for the domain validation, as it creates the necessary DNS record.

After the domain is validated and you set the domain purpose, the Office 365 Admin portal detects that your domain provider is 365, and you can then click on “Add Records” to add your DNS records.

Before adding them, you can see the detail by expanding “View the DNS records we’ll add”.

2

A GoDaddy logon window will pop up. Enter your username and password.

3

Click confirm to accept the changes on your public DNS zone.

(Note: Apologies about the Portuguese screenshoots)

You will then get the confirmation that the changes were done.

And if you login to your GoDaddy account and edit the zone file for your domain, you will see all the new DNS records there.

That’s it. As simples as that! Enjoy!
