Thanks for the reply.

Accepted domain is already added in on-prem and i have users with that SMTP primary address.

 

So now, i need to add the domain in azure - > add one more UPN for the domain in on-prem AD -> do a sync -> then add the domain in office 365 ?

 

is this correct ?

Hi Devaraj,

 

Validate the domain only on Office 365 you do not need to validate on Azure.

 

Then add the upn and do a sync.

    Sorry, I meant,

     

    - Verify the domain in Office 365 for Azure AD sync

     -  then,  add UPN suffice in on-prem AD for the accepted SMTP domain - do the sync

    - Adding accepted domain in office 365 exchange online  will automatically happen ?

     

    Any other consideration i need to take ?

      Hi Devaraj,

       

      Yes, that's the process.

       

      After you validate the domain in Office 365 domain's it will be added in Exchange Online.
