You don't have to go to the SharePoint site to check out documents from MS Teams. If your SharePoint site is set up with permissions to check-in/check-out documents, that is a great start. From there:
1. Click on the document
2. In the purple 'Edit' box on the top right, hit the arrow and click 'Open in Desktop App'
3. The document yellow box at the top that says: CHECK OUT REQUIRED To modify this server workbook, you must check it out. And there's a button that says Check Out. Click that.
4. The document is now checked out and anything you change is automatically saved.
5. HOWEVER, you do have to go to SharePoint to check back in, but this can easily be done by the Project Manager or whomever owns the SharePoint Site.
Yes, it's a small pain and would be nice to just check-in/check-out directly in MS Teams, but for now this is what has to be done.
How on earth did MS create the ability to make private channels......but not give us the option to convert a currently public channel to private?!? Hello?! We've been using Teams for years now! This should have been a no-brainer!!
Due to prioritization of other work-items this has been moved to the backlog. We will update when it is being actively worked on again.
Why is this on the backlog when you are working on other UserVoice items with LESS votes? Clearly this is something many people want, it should be moved up on the priority list!!
IT Admin’s now have the ability to configure apps on the left navigation of Microsoft Teams. You can learn more about that feature here: https://docs.microsoft.com/en-us/MicrosoftTeams/teams-app-setup-policies
As announced at Ignite we are currently working on enabling desktop users to add personal or favorite apps to their own left navigation.
