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,
Thank you for your update. I tried your script but it didn't work.

I opened a ticket for this and a MS engineer tested some and now he is looking into the transcript.
