Authentication in Hybrid Enviroment to Outlook, Teams
Hi all,
We have hybrid enviroment. Local AD sync to AAD with AAD Connect. Autentication using Pass-through Authentication and SSO.
Exchane Online configured with HMC in Modern Authentication.
All works fine.
In local AD our UPN is xyz@zyx.local, I configured AAD and users can login to O365 using ther mail adres with routable doman xyz@zyz.com.
I have question can I set up Outlook, Teams to using Windows credential?
Right now users have to enter ther login and password.
In username is fill up UPN alias with xyz@zyx.local it's also bad behavior
I know the UPN should be the same as Primary SMTP but we can't do this.
Regards'
Rafal

VasilMichev I'm not sure if this solution will helpful with non routable domain in local AD in UPN
