I know that there are naming policy settings available for Office 365 groups applied to the mailbox addresses. But is there a way to enforce a naming policy only on the group mailbox rather than everywhere?
We want to create a "NewProject" group and the mailbox automatically named "newproject.team@our.org".
The reason to ask is that we have mail aliases (before migration to Microsoft 365) that can be hijacked that way, i.e., if someone creates a group "ceo@our.org", the group mailbox will start receiving emails sent to the alias. So if there is an alternate solution than a suffixing mailbox, it will be great too.
Any help is appreciated.
