Office 365 Groups
The problem is Groups are not Exchange objects, they are AAD objects. While you can certainly govern some settings via the ExO cmdlets, AAD remains the source of authority, thus the portal requires you to have the necessary permissions to run the corresponding AAD cmdlets/API calls.
That said, if you are OK with using the EAC or PowerShell, you can certainly use an Exchange admin (or non-admin with the relevant permissions) to manage them. All you need is to have the Mail Recipients role assigned.
To bring everyone up to speed, I reported the problem I experienced to the Azure AD team and they found an issue that's now resolved. Group management via delegated admins works as expected. I'll document this and publish an article on Petri.com to report what I found.
