Azure AD Windows 10 and Azure AD Connect
AJ Kertis what UPN are you creating on the Azure AD side for your users? And does it match the upn for the user in your on prem AD?
If you are trying to syn a upn like first.last@yourdomain.com and you have not added the domain yourdomain.com to your Azure tenant, then the sync will automatically default to first.last@*.onmicrosoft.com
jasonsch69 we originally started with Office 365 but yeah the UPN used for everything Azure and Office 365 is the same as the one I'm trying to use and is set accordingly in our local AD.
first you create your tenant "name".onmicrosoft.com
second you have to add your custom domain like "yourdomain.com" to your tenant
3rd your onprem UPN needs to be username@yourdomain.com - if its not than please add it to your onprem AD and change your upn (be careful that needs to tested)
4th you install AdConnect and sync your user
5th if this is successfull than you are able to see your users in aad ->users with same upn just like in your onprem-AD
6th try to login to portal.azure.com or myapps.microsoft.com with username@yourdomain.com
7th you also be able to login to your domain-joined-devices with username@yourdomain.com
