We have just moved from Exchange on premise to Exchange Online. I've recreated the resource mailboxes and they are visible and work. However, by default, when any user looks at the calendar they only see "Busy" along with the timeslot details for any existing reservations..
I want everyone to be able to see the organizer and the subject.
I seem to recall in our on premise we managed this by opening the resource mailbox in OWA and modifying the settings there. I don't see any related settings when opening the new EO resource calendars in OWA.
I've looked at the Set-MailboxFolderPermission and Add-MailboxFolderPermission powershell commands as an option but not sure if that is the best way and I can't seem to get the syntax right either.
