OneDrive is a cloud-based storage service where you can view, browse, upload, and share the files you saved online to OneDrive.
With Office 2016 and OneDrive, you can co-edit and share files right in your Office apps like Word, Excel, PowerPoint, and Visio. The OneDrive sync client and Office work together to sync documents in OneDrive and let you work with other people on shared documents at the same time.
Most of the time, Office 2016 automatically syncs changes to Office files saved in OneDrive. On rare occasions, if an Office app closes unexpectedly, or if changes made from different devices can’t be resolved, a sync conflict can occur. If you run into problems with changes not syncing or merging properly, you might want to change your sync settings in OneDrive.
This tutorial will show you how to turn on or off use Office 2016 to sync Office files that you open with OneDrive for your account in Windows 10.
