Managing calendar resource delegates with groups?

[Daniel Niccoli]

We have about 40 mailbox-enabled rooms (meeting rooms). All of them have resource delegates assigned. The company grows rapidly and the delegates change very often. This not only puts a load on our help desk but also the more rooms and changes there are, the more mistakes creep in.

To ease this up, we created Office 365 groups and assigned those groups as resource delegates on the mailbox-enabled rooms.

Set-CalendarProcessing meeting-room-1@mycompany.onmicrosoft.com -ResourceDelegates meeting-room-1-delegates@mycompany.onmicrosoft.com

The delegates are receiving the approval emails but they cannot approve the requests. Troubleshooting the issues showed, that Set-CalendarProcessing does two things.

1. It forwards approvals to the resource delegates.
2. It adds the delegates to the mailbox folder permissions with Editor rights.

However, the Office 365 group is not added to the mailbox folder permissions and even when I try to add the Office 365 group manually, it doesn't work.

Is there any way to set up a group of people as resource delegates of mailbox-enabled rooms without adding their user accounts directly?

Afaik no. Even if you can technically add a group to the relevant property, the functionality will not be available as you've noted already. You can easily script a solution that goes over the list of rooms say once a week and adjust their delegates based on membership of some group.
