Office 365 - allowing external users to view availability of and book a meeting room

I need to allow external users (not on our domain) to view availability of meeting rooms (setup on our domain on Office 365) and then be able to book the room - as if they were users on our domain.

Is this possible in Office 365?

Thanks

Steve

Hi Steve,

 

We can use PowerShell to allow external users book Office 365 meeting rooms. Here are the steps:
1. Connect to Exchange Online using PowerShell: https://technet.microsoft.com/en-us/library/jj984289(v=exchg.160).aspx
2. Run this command: Set-CalendarProcessing *** Email address is removed for privacy ***  –ProcessExternalMeetingMessages $True

 

After that, the external user can add the address of the room mailbox in the To field to book the room.

 

Regarding the room availability, you can share the calendar to external users referring to the article below: https://support.office.com/en-us/article/Sharing-your-calendar-in-Outlook-Web-App-7ecef8ae-139c-40d9-bae2-a23977ee58d5

 

Before that, you need to grant yourself Full Access permission of the room mailbox. Then refer to the following article to open another person’s mailbox in a separate browser window in OWA:

Feel free to post back if it doesn’t meet your requirement.

 

Thanks,

Chris
