After opening a file saved in OneDrive, OneDrive for Business, or SharePoint that is synced using a sync client, you may experience that the AutoSave is incorrectly disabled or greyed out. Hovering over the AutoSave toggle, the tool tip will prompt you with the following message:
AutoSave Not Available. This file location doesn't support AutoSave. Save to OneDrive or SharePoint Online if you want to use AutoSave.
This issue impacts the Office 2016 August 2017 update, Version 1708 (Build 8431.2079) and later for customers on the current channel (CC). Coauthoring and autosave are not yet supported for customers who are on the FRDC or SA (semi-annual) release channel.
This issue is now fixed in Version 1708 (Build 8431.2094) for current channel (CC) customers. To get the update immediately, open any Office 2016 app and choose File > Account > Update Options > Update Now.
If you are continuing to experience or have not updated yet, you can use the following workaround:
Open the Office app, click on File > Open and navigate to the server location (OneDrive or SharePoint).
Using a web browser, open the file directly from SharePoint or OneDrive where the file is stored.
Note - Coauthoring and autosave are not yet supported for customers who are on the FRDC or SA (semi-annual) release channel. These features are only available for customers on the current channel (CC).
