Using Graph API to create a OneNote tab in a Teams Channel
Hello, I'm trying to create a new tab in an existing channel that opens a OneNote notebook using Graph API. According to official documentation (https://learn.microsoft.com/en-us/graph/api/channel-post-tabs?view=graph-rest-1.0&tabs=http), the call should look like this: POST https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}/tabs { "displayName": "OneNote", "email address removed for privacy reasons" : "https://graph.microsoft.com/v1.0/appCatalogs/teamsApps/0d820ecd-def2-4297-adad-78056cde7c78", "configuration": { "entityId": "<Notebook_id>", "contentUrl": "<OneNote_notebook_url>", "websiteUrl": "<OneNote_notebook_url>" } } It worked smoothly, but since recently, when you open the tab in Teams (desktop or web), it shows an error message stating that "the application can't be reached". In the end, the tab is created but OneNote notebook is not opened. Reading the official documentation here: https://learn.microsoft.com/en-us/graph/teams-configuring-builtin-tabs#onenote-tabs it mentions that when creating OneNote tabs, "configuration is not supported". Does this mean now you can't specify the OneNote notebook to open in the tab using Graph API? Any suggestions or recommendations? Thanks in advance! Ferran

Access issue when adding a OneNote Tab in Teams
Hi, Adding a OneNote-Tab, via the Graph-API , for a OneNote which is in the same Team works without errors. But when I try to add a OneNote-Tab for a OneNote which is located on another SharePoint site (not in the Team assigned team site) I get this error. By the way, I have access to the corresponding OneNote and a manually created Tab to the OneNote works... Does anyone have an idea or a similar problem? Bye and thanks Jens
