Microsoft 365 Groups now supports new ways to show and hide groups in any Outlook client or the address book.
This message is associated with Microsoft 365 Roadmap ID 64479.
When this will happen
You can now set visibility of Groups using Microsoft Graph in addition to PowerShell. How this will affect your organization
We have introduced two new properties to the Group Resource Type in Microsoft Graph: hideFromOutlookClients and hideFromAddressLists. This changes allows you to show or hide Microsoft 365 Groups in any Outlook client or the global address list (GAL).What you need to do to prepare
The default value for both properties is false, and they are only retrieved when using $select.
To prevent a group from showing in the Outlook left-hand navigation, set the hideFromOutlookClients property to True.
- The group name won’t resolve during the creation of a new message in Outlook.
- This also sets the hideFromAddressLists property True to prevent the group from showing in the Global Address List (GAL).
To allow a group to show in the Outlook left-hand navigation, set the hideFromOutlookClients property to False.
- The group name will now resolve during the creation of a new message in Outlook.
- This also sets the hideFromAddressLists property to False.
Changing the value of hideFromAddressLists does not change the value of hideFromOutlookClients.
- Setting hideFromAddressLists by itself will control whether the group is hidden or shown in the GAL, but will have no impact on whether the group shows in the Outlook left-hand navigation or resolves during the creation of a new message.
