Try it!
After you share a file, you can collaborate with others and work at the same time.
-
See who else is in the document and where they're working.
-
A presence indicator shows where someone is making changes. See any changes right as they're being made.
-
Add comments and @mention others to get input right where you want.
Note: Co-authoring works similarly in Word, Excel, and PowerPoint on Windows, Mac, and on the web.
Use Version History

With your file saved to OneDrive or SharePoint, use Version History to go back to a previous version of a file if someone makes a change you don't want.
Note: Besides a few differences, Version History works similarly in Word, Excel, and PowerPoint on the web and in the desktop apps.
