One of the first things you will notice when you start saving Office files in Teams (SharePoint) or OneDrive, is that the save button is replaced with Autosave.
This means a Word document is saved continuously, so you won’t risk losing your work. At the same time, it’s automatically synced to the cloud. With these features, you can easily collaborate in Word in real-time with one or more colleagues
Go to the Files tab in Teams. Here, you can create a new Word-, Excel-, or PowerPoint document, or upload one from your computer to share. You can also send a link to invite others to collaborate on the document with you. As you see each other's updates, you can chat and share ideas to further improve the document.
Documents can also be opened from the banner Files in Teams. Mark the file you want to open, and click on ... (several choices). From the menu that shows up you can select to Edit in Teams, Open in app, or Open in browser.
When multiple people work on a Word document in real time, you can see who is available and the changes being made. To avoid editing the same content at the same time, Word automatically locks the section each person is working on, ensuring no one overwrites each other’s work.
