Different naming policy for mailbox and Office 365 group
Hello,
I know that there are naming policy settings available for Office 365 groups applied onto 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.

- You can block certain "words" to prevent them from being used in the policy (https://docs.microsoft.com/en-us/microsoft-365/solutions/groups-naming-policy?view=o365-worldwide#custom-blocked-words). The naming policy itself only applies to Microsoft 365 Groups, there is no way to have a policy that applies to user mailboxes in Exchange Online.
You can also limit the creation of Groups so that only admins, or designated people are allowed to do it.Thank you, VasilMichev! 🙂
