Hi,
You will need to do the following:
- Validate the domain on Office 365
- Add the UPN to onprem
- Add the domain to the Exchange Onprem
- Do a Delta Synchronization on AADConnect
- Run Hybrid Configuration Wizzard to accept new domain
- Verify Connectors
- Create a test user and test mail flow internally
- Change MX record to Office 365
- Test mail flow externally
- Migrate the test user to Office 365
- Create or change the users to the new domain
- Migrate Mailboxes to Office 365
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 ?
