This article describes the process of associating a registered domain with Office 365.

Why do this?

When a new O365 tenant is created, all users will be created as <name>.<companyname>.onmicrosoft.com. e.g. [email protected]. Microsoft provide this subdomain as an initial login to O365.

To enable users to login using a registered domain (like [email protected]), you must prove to Microsoft that you own this domain.

NB. This has no effect on existing services like email hosted outside of O365, it is merely a way of authorising the use of a domain (collset.com) in O365.

Pre-requisites:

• Access to O365 as admin
• Access to the domain console

How To:

IN O365:

1. Log in to Office 365 and go to Set Up > Domains > Add Domain

2. Enter the domain as name.com (e.g. collset.com) and hit next

3. Choose to enter a TXT Record unless advised otherwise

4. Copy the details of the TXT record, this is needed in the next step in another system

IN YOUR DOMAIN CONSOLE:

5. Take the TXT record details from step 4 and enter them against the domain console

BACK IN OFFICE 365

5. Verify the domain is there

6. If yes, all good, if no, review the details and go through 4 and 5 again*
