For a domain to show up in the suffix of a UPN or proxy address that domain must be verified in the AAD domains section that you mentioned. That is your problem. Verify the domains and they will appear.
azure ad sync proxy address
Hello:
we have configured azure ad sync with all the attributes but somehow only proxy address is showing up now is @keyman .com But on prem we also have @domainabc.com @domainxyz.com etc.. Issue is only proxy address is showing now which ends with @keyman .com none of the @domainabc.com or @domainxyz.com is showing up on azure ad side.
How do we get all the proxy domain addresses synced to azure ad. Currently under Azure ad admin center>settings>domains, we have only one domain(domain.com) listed. do we need to list all the domains(domainabc.com and domainzyz.com) under there? also do we need to run the azure ad connect wizard again?
also can you please reference Microsoft technet article about this?
thanks
