Add SharePoint site as a App to the Teams
Hello everyone, we used this integration for a SP for some time now, and all of a sudden wie get 401 unauthorized messages when trying to open it.
Does anyone face the same issue, or has an idea what we could do to resolve this?
The Site is integrated just like shown in the original post.
Penglert Try opening the SharePoint page in the associated 'Teams' channel, under the 'Home' tab. Then go back and try your tab app.
For some reason, new Teams is failing on authentication. This is the point at which it was failing for me. My assumption is the Teams channel is able to reauthenticate within Teams, meaning the Tab app works as expected.
I recommend you use the Viva Connections app. It is the supported method by Microsoft and gets updated. You can even set the Viva Connections app to show the SharePoint landing page as a default, skipping the Viva Connections landing page, making it very similar to your current situation. Setting up the default experience to SharePoint instead of Viva Connections landing:

It doesn't seem to work with O365 environments that have SharePoint setup using vanity urls which some companies still have through legacy agreement with Microsoft.
- Note that using Viva Connections doesn't allow you to access a SharePoint page view in the mobile app, which seems to be the OP's requirement.
MsFox how do you know? I have Viva Connections defaulting to the Sharepoint site in the desktop Teams app, but haven't dug deep into the mobile side yet. It would be good if the Sharepoint site was an option to open in the Mobile app considering they have a button for it, why not just allow us to start there! Just wondering if you have dug into this yourself and confirmed this. Any additional information is appreciated!!
