Microsoft announced real-time co-authoring is now available as a first-look for Word documents stored on OneDrive as part of the latest Office 2016 Preview release.
According to Microsoft blog, when two or more users running the latest preview open the same Word document from OneDrive, they can co-author with others in real-time, which allows them to see the cursor location and text edits made by the other users automatically appear as they happen.
You are encouraged to try real-time co-authoring on OneDrive today. If you are receiving regular updates throughout the preview, you should have received this functionality as an update by 11 a.m. this morning.
To try out this feature, all you need is a Word document stored on OneDrive and two or more people running the latest preview. Make sure to give both users edit permissions so they can both edit the file. If this is the first time you’ve tried real-time co-authoring, you will see a prompt in the upper right corner of Word asking you if you’d like to automatically share your changes.
All you need to do is click Yes to join the experience. Once both authors have clicked Yes, you’ll see a flag representing the other author’s cursor position and then you will automatically see their edits come in.
