Connect to Exchange Online for Room Reesource Data



I try to elaborate a dashboard in order to show the usage of the meeting rooms.

When connecting to exchange online what is the right permission to set in order to show only the free and busy information of a meeting room ?


I tried "Folder visible" and "Limited details" but it isn't enough and I cannot access. I also tried "Reviewers" but it is too much, I can see all the details and the text of the different meetings. If I want to share this dashboard within the company, I cannot give the "Reviewer" permission to everyone ...


I also get only this Failure




Thank you in advance for your answers, best regards.

Hi @DominiqueHeere ,

I'm not quite sure what you mean. Does it mean you want shared users to show only busy/free information?

Please refer to the following document to see if it helps you.

more free/busy information with shared users in Microsoft Outlook 

  • First, sign into your Microsoft Outlook account.
  • Go to the calendar selection by clicking on the calendar icon.
  • Click on “folder” in the menu bar.
  • Now click on “calendar properties”.
  • In the properties panel go to “permission”.
  • There are four kinds of permission levels: select the one that’s most relevant to the amount of information you want to send.
  • Click on “OK”
