Collaborate on Word documents with real-time co-authoring
When someone shares a Word document with you, the email you receive includes a link that opens the document in your web browser: in Word for the web. Select Edit Document > Edit in Browser.
If anyone else is working on the document, you'll see their presence and the changes they're making. We call this coauthoring, or real-time collaboration.
From here, if you'd rather work in your Word app, switch from Editing to Open in Desktop App, near the top of the window.
Want a guided tour? Download this Collaborate in Word learning guide, or type Collaborate in the search box in File > New in Word (works best in versions 2016 and later for Windows).
You'll still be coauthoring, as long as you're a Microsoft 365 subscriber, using one of these versions of Word:
Word 2016 for Windows
Word 2016 for Mac
Word on a mobile device (Android, iOS, or Windows)
If you're using an older version of Word, or if you're not a subscriber, you can still edit the document at the same time others are working in it, but you won't have real-time collaboration. To see others' changes and share yours, you'll have to save the document from time to time.
