Thank you for your post!

When you say change the identity issuer, are you referring to the on.microsoft.com extension at the end of your user?

Are you able to create a new user with your domain (i.e. user.contoso.com)?

Any additional information or screenshots would be greatly appreciated.

Thank you for following up on this!

When it comes to changing the User Principal Name for your user - for example, aaa.onmicrosoft.com to bbb.onmicrosoft.com, you can do this by:

1) Login into the Azure Portal
2) Select Users -> Navigate to user aaa.onmicrosoft.com
3) Select Edit -> Change the User Principal Name
4) Save.

Note: Prior to changing a user's UPN, please make sure the UPN (aaa.onmicrosoft.com) isn't being referenced by Apps, Azure resources, MFA apps, etc.

I hope this helps!

If you have any other questions, please let me know.

So, my User Principal Name is correct but the Identities is what I want to change. Instead of 123.onmicrosoft.com, maybe my company name.onmicrosoft.com

Can this be done?

Thanks!
