Hello,
I'm trying to create new group with predefined classification (tenant-level groups settings with ClassificationList were successfully created via PowerShell - using approach from the following article https://joachimloe.com/2018/01/19/classifications-for-office365-groups-and-microsoft-teams/. In my test I also use 3 classifications: Internal,External,Confidential).
When I tried to create new Group via Graph client library for .Net and specified Classification explicitly:
var newGroup = new Microsoft.Graph.Group
{
DisplayName = displayName,
Description = description,
...
Classification = "Confidential"
};
...
var addedGroup = await graphClient.Groups.Request().AddAsync(newGroup);
I got the following error: Property 'classification' is read-only and cannot be set.
When I tried to update classification of existing group via Graph API:
https://graph.microsoft.com/v1.0/groups/{groupId}
{
"classification" : "internal"
}then got Bad request with the same error: Property 'classification' is read-only and cannot be set.
The only method which uses classification for creating new group which I found at the moment is CreateGroupEx from Sharepoint API:
POST https://{tenant}.sharepoint.com/_api/GroupSiteManager/CreateGroupEx
{"displayName":"Test","alias":"Test","isPublic":false,"optionalParams":{"Description":"","CreationOptions":{"results":[]},"Classification":"External"}}
Is there a way to specify classification for the group via Graph API?
