Share e resource with external persons (M365)

If you want to share one or more resources with an external person you can create an iCal link and allow external bookings:

• Create an iCal link:
  To publish a room resource by iCal you need to have access to the Exchange online PowerShell module

  You can use the following command to publish the resource for one year:

  Adjust the identity with the Mail of the room.
  

  Code Block
  Connect-ExchangeOnline

  Code Block
  Set-MailboxCalendarFolder -Identity room@myorganization.com:\calendar -PublishEnabled $true -DetailLevel Full -PublishDateRangeTo OneYear -PublishDateRangeFrom OneYear

  To get the link of the share, you need the following command:

  Code Block
  Get-MailboxCalendarFolder -Identity room@myorganization.com:\calendar

...

• Allow bookings from outside:
  For all resources:

  Code Block
  Get-Mailbox| where {$_.RecipientTypeDetails -eq "RoomMailbox"} | Set-CalendarProcessing -ProcessExternalMeetingMessages $true

  Only for one resource:

  Code Block
  Set-CalendarProcessing -Identity room@myorganization.com -ProcessExternalMeetingMessages $true

Once you have done this, you can share the iCal link with external. The external people can then invite the meeting room as attendee. The room will then accept the booking (if it is free) and the ROOMZ display will also show the appointment correctly.
