Microsoft Office 2016 – Improved Version History

Office 2016 lets you view or go back to earlier drafts of your documents so that you can edit and share your documents with confidence. Version history is maintained for documents stored on OneDrive for Business or SharePoint Online.

How to open a previous version:

1.     On the File tab, select History. The History tab opens to the right of the document.
Note: If you do not see History on the File tab, your document is not saved to the cloud or to a location that has version history tracking enabled.

2.     On the History tab, select the version of the document you want to review.
