In order to ensure private meetings show correctly as private in Outlook and within RICOH Spaces, we recommend the following settings:
Change the setting of the room calendar. The user can change the setting using PowerShell: https://learn.microsoft.com/en-us/powershell/module/exchange/set-calendarprocessing?view=exchange-ps
Recommended settings would be the following for every Microsoft room:
- AddOrganizerToSubject : False - avoid adding host name to subject 
 
- DeleteSubject : False - avoid to delete subject 
 
- RemovePrivateProperty : False - avoid to remove private flag 
 
- DeleteComments : False - avoid to remove body 
 
Command to apply above changes to all rooms.
Get-Mailbox -RecipientTypeDetails "RoomMailbox" | foreach {Set-CalendarProcessing -Identity $_.PrimarySMTPAddress -RemovePrivateProperty $False -DeleteSubject $False -AddOrganizerToSubject $False -DeleteComments $False}
