O365 meeting title, privacy, and description settings
By default, when you schedule a meeting in O365 and add a meeting room, the room’s calendar does not apply meeting privacy settings—private meeting titles may be visible to anyone with access to the room calendar. To maintain privacy, you can modify your organization’s settings in O365 so that meeting titles for events marked as “Private” are hidden on room calendars. In addition, it is possible for the meeting title to include the organizer's name, or for Sync to not be able to read the title at all. This guide explains how to adjust these settings using PowerShell to ensure you have the right experience.
1. Connect PowerShell to Microsoft 365
Open Azure PowerShell or Azure Cloud Shell as an administrator. Make sure you're connected to your Microsoft 365 tenant.
If you need help connecting, see Microsoft’s official guide: Connect to Microsoft 365 with Microsoft Graph PowerShell.
2. Update Resource Mailbox Settings
Private meetings
Run the following PowerShell command to ensure that private meeting details stay private on room calendars:
Get-Mailbox -RecipientTypeDetails RoomMailbox | Set-CalendarProcessing -RemovePrivateProperty $false
The RemovePrivateProperty parameter controls whether the “private” status on meetings is preserved or cleared.
By default, this is set to true, and the private status is removed, and meeting details may become visible. Setting this to false ensures the private status is preserved, so meeting details (like the meeting title) remain hidden on room calendars.
Meeting organizers can continue to mark meetings as private during scheduling, ensuring confidential information always remains protected.
Removing organizers' names from meeting titles
Run the following PowerShell command to ensure that the organizer's name is not added to the meeting title:
Get-Mailbox -RecipientTypeDetails RoomMailbox | Set-CalendarProcessing -AddOrganizerToSubject $false
Make meeting titles visible to Sync
Run the following PowerShell command to ensure that Sync can show the meeting titles on Logitech Room Booking and Logitech View:
Get-Mailbox -RecipientTypeDetails RoomMailbox | Set-CalendarProcessing -DeleteSubject $false
If DeleteSubject is set to true it would prevent Sync from being able to show meeting titles on Logitech Room Booking and Logitech View
For more details, refer to Microsoft’s documentation: Set-CalendarProcessing (ExchangePowerShell).
These settings will enable private meetings to remain private even when meeting titles are shown through Logitech Space Management solutions, and ensure that the correct meeting titles are shown when they are not private.
Apply settings to a specific room only
If you need to apply settings conditionally or for a specific room, adjust the command as follows:
Set-CalendarProcessing -Identity "Room Name or Email" -RemovePrivateProperty $false
Replace "Room Name or Email" with the actual room’s name or email address.
