Edit Office 365 Group ProxyAddresses
There is an issue with Office 365 group and email aliases. If a user creates a group named "All amazing people" it will create Office 365 email alias firstname.lastname@example.org. But in certain instances there are customers (like us) that use Azure AD Sync. So when I create distribution group in our AD, with same email name I get a sync issue.
If I rename Office 365 group and change email address, for some reason all aliases are kept, so the only solution is to remove Office 365 group. I have worked with support when it was mentioned "remove group, sync, restore group" except this doesn't work since instructions are explicitly saying "Caution: If a new group has been created with the same alias or SMTP address as your deleted group, you will have to delete that new group before you'll be able to restore your deleted group"
We need ability to edit/remove aliases (ProxyAddresses attribute in Azure AD Groups)
