Resource mailbox's calendar shows "Blocked" instead of the organizers Name

Question

Hey Everyone,

I recently created a new Resource Calender in our Microsoft 365 Online tenant.

This Resource is one of our company pool vehicles.

Unfortunally, if someone books the car, the calender only says "Booked", but we would like it to show the organizers name, so we can now, who took the car.

Our other resource calender has this set up properly, but unfortuanlly this was done, before i was employed here, and it is not documented how it is done.

I tried some online searches, but i can only find, how to reverse this, and instructions for Exchange Server Enviroment.

Is there someone out there, who can help me with this?

Best Regards

Michael Becker

You will have to adjust the permissions on the calendar, and/or the Calendar processing settings. Let's start with the former, check the permissions via:

Get-MailboxFolderPermission resourcename:\Calendar

We're interested in the Default entry therein, you want it set to LimitedDetails if you want to see the organizer info.

Set-MailboxFolderPermission resourcename:\Calendar -User Default --AccessRights LimitedDetails

Apart from that, ensure that the Calendar processing does add the Organizer info to the subject:

Get-CalendarProcessing resourcename | select AddOrganizerToSubject,DeleteSubject
If needed, adjust it with:

Set-CalendarProcessing bathroom -DeleteSubject $false -AddOrganizerToSubject $true
