O365 - Change suffix of a Shared Mailbox
Is it possible to rename and change a suffix of a shared mailbox please? mailto:Department@contoso.com to mailto:Department@fabrikam and preserve its content and permissions?
Thanks for that. Not so easy in a hybrid environment or is it?

Changing the suffix makes no difference in Hybrid either, the article you're citing is for different issue (cloud-created shared mailbox that you want to access cross-premises).
