Being that I still have an on-prem Exchange server, I have not had the need to edit any attributes. Without the on-prem, what attributes are needing to be edited?

    This is something new i learnt today :) https://www.itpromentor.com/remove-hybrid-keep-sync/

    The Windows Server Essentials Experience Role is something i havent fiddled around with.. but really cool for end customers who want to throw out as much possible from on-premise :)

    Need to urgently fiddle with this in my lab now..

    Great share @DominikWagner ..

    Thanks Dominik. That article is very enlightening. But it brings me back to my original question. If I create email addresses for new accounts, add aliases, hide email addresses, do all email management in the cloud, what is the purpose of the on-prem Exchange server, other that to be in a "supported" configuration? In my opinion, at this point, the on-prem is totally useless since NO email management is done on-prem through AD or Exchange.

     

    I create a new account in on-prem AD, AAD Connect syncs it to Azure AD, I go to the O365 cloud console, add a license to the new user account, and it's done. Nothing done on-prem. This is why I don't understand why Microsoft is trying to force me to keep an on-prem Exchange server, "free" or not.

      Just to give you some examples about what you may not be able to configure with Azure AD Connect in place without Exchange on-premises, try the following over Exchange Admin Center in O365 :

       

      1. Hide a mailbox from the address book 
      2. Update mailbox alias
      3. Add or edit an SMTP address
      4. Change mailbox delegation settings

       

      Please share with us the results of those actions, I would also be glad to have your thoughts regarding the results. 

       

      Thank you

       

      Kind regards

        I beleive these actions can be completed with a powershell command or two!
