Autopilot support for multiple Domains on a single tenant

Contributor

My office 365 tenant includes multiple domains to include the following:

 

mycompany1.com
mycompany2.com

mycompany3.com


I have also setup Windows Autopilot (AAD Join) for my tenant.

 

However only email addresses from mycompany1.com are recognised accepted when enrolling Windows 10 devices.

 

How do I add the other domains to the accepted list of email domains for Autopilot?

Hi,

You could check out this link... as normally you would login with the upn and not with an additional emailadress..

 

Why not changing the upn for that user/s who want to start using autopilot?

 

but maybe enabling it would work ? (not sure as I didn't tested it myself)

@Rudy_Ooms thanks for the response.

 

The UPN does match the email address already but I think with the article, I could possibly use another one of the email aliases.

 

So in other words, user@company2.com is the non working UPN domain, but I guess I could test and see if user@<tenant-name>.onmicrosoft.com might work also as a possible workaround.

 

 

It's worth a try i guess :) please let us know the outcome
