I am trying to remove an old email address from a user in AD thats sync via AAD Connect as I would like to use the email address for a DL.
In AD I have removed the SMTP address from proxyAddresses and forced a sync but the email address is still listed in the Office portal, how can I remove the address?
UPN - firstname.lastname@example.org
email to remove from user - email@example.com
Current primary email - firstname.lastname@example.org
