Hi MOONSO KO,

You can try the following cmdlet to update the primary SMTP address of the O365 group.

Set-UnifiedGroup -Identity old@mydomain.com -EmailAddress @{remove=”SMTP:old@mydomain.com”;add=”SMTP:new@mydomain.com”,”smtp:old@mydomain.com”}

This should update the primary SMTP address to the new@mydomain.com and set the old@mydomain.com to a secondary SMTP address.

Hi Jason,

I'm in the same position as Moonso Ko. In my case, attempting your workaround did alter the email addresses, but not the primary SMTP address for the group, and returned the error;

There is no primary SMTP address.
