Enable users to view calendar information of Room mailboxes

On Exchange Online Room mailboxes do not share calendar information by default. You will only be able to see if the Room is busy or not. This blog describe how you enable the Room’s calendar to show more information to all users.

First we need to connect to Exchange Online with PowerShell. If you don’t know how to connect, please read this blog post (http://blog.ctglobalservices.com/bfa/managing-office-365-with-powershell/).

Start setting the Room calendar to show more details by default, to do so type in this PowerShell command.

Now we are able to see more information.

To enable Room calendar to show subject of the meetings, please use this PowerShell command.

Now we are able to see subjects, however this will only works on new meetings or if you update an existing meeting in the calendar.

Enjoy.

    Thanks for sharing this Brian, its really helped me out when configuring our org’s room mailboxes.
    The change helps staff members identify who has booked the room and for what purpose.

    I have a conundrum here, how do I reset this?

    I have tried Set-CalendarProcessing -Identity Meetingroom -AddOrganizerToSubject $false -DeleteComments $true -DeleteSubject $true but the new meetings I book still shows the subject of the meeting. I would like to revert it to only show the name of the person booking the room/meeting.

    Best regards

      Change -AddOrganizerToSubject $false to -AddOrganizerToSubject $true

      Set-CalendarProcessing -Identity Meetingroom -AddOrganizerToSubject $true -DeleteComments $false -DeleteSubject $true

    Is there any option that allows to add the shared calendar to all users automatically?

    Hi,
    I have a resource online that certain users are set to be delegates with Full Access permission, but for some reason, when they try to access that calendar in Outlook, it tells them “Cannot open calendar for user.” Why is that? Thanks in advance.

    How do I show the room calendar? I want all my users to be able to see what is scheduled for the room in a month view? Anyone know how to do this?

    Why not just set the access rights to “Reviewer” and not using the second line of code at all?

    Set-MailboxFolderPermission -Identity ROOM@DOMAIN.COM:calendar -User default -AccessRights Reviewer

    Can i set a room calendar to show just the organizer information and nothing else ? If so how

    Another way without coding:
    1: create an email enabled security group (create it in O365 portal or in Exchange admin portal)
    2: Add employees to the group
    2: Add the group to the Meeting room as owner in Exchange admin portal “mailbox delegation”.
