MS Teams创建的收藏夹组不能设置为收藏夹

Question

I'm trying to add and remove favorites of groups. Therefore MS Graph provides the groups/{groupId}/addFavorite Endpoint to set a group as favorite. When I create a group eg by Outlook to favorite this group is possible. When I create a group over MS Teams the endpoint returns me an OK but the groups is not set as favorite. Why does it not work?

I figured out that in via MS Teams created groups, the outlook and calendar icon is hidden. However, it is possible go to outlook for this group by enter the link by hand in the browser. There it is not possible to set the group as favorite over the setting too [See below image Group created via MS Teams ].

For a group created by Outlook it is possible to favorite it [See below image Group created via Outlook ].

Group created via Outlook

Group created via MS Teams

This behavior is the same as in the MS graph endpoint. So when I try to set a via teams created group as favorite via groups/{groupId}/addFavorite the endpoint return ok but nothing happens. I expect, that it should not matter, where I create the group to use the favorite endpoint.

Answer 1

I found out that when you create a group via MS Teams the UnifiedGroup property HiddenFromExchangeClientsEnabled is true . So Outlook and Calendar is not shown and it is not possible to get the isFavorite property. Now I set the HiddenFromExchangeClientsEnabled property to false and now it is possible to set it as favorite. :-)

Use set-UnifiedGroup -identity "TEAMNAME" -HiddenFromExchangeClientsEnabled:$false -Verbose to set the property.

The next challenge will be to set this property on creation for each new group via ms team.
