Improvements and fixes

This security update contains improvements and fixes for the following nonsecurity issues:

• Translates some terms in multiple languages to make sure that the meaning is accurate.

• Assume that you have a Project .mpp file that’s stored in a SharePoint document library. When you click the file name, the project opens but you don’t see a banner that offers you the ability to edit or check out the project. Instead, the project may keep in a read-only state and you can’t save or check in changes.

• When you try to reply or forward an email message that contains a linked image, Outlook 2016 freezes before the image is displayed.

• This update provides the latest version of OneDrive for Business for Office collaboration synchronization integration. It also enables coauthoring of Office documents that are synchronized by OneDrive in a reliable and high-performance manner. This update lets you use Office together with the latest version of OneDrive for Business for improved online and offline user experiences for all files that are synchronized.

Significant changes to the user experience include the following improvements:
* The ability to quickly open OneDrive synchronized files from anywhere (File Explorer, Most Recently Used list, or websites). This enables Office applications to open the correct file and keeping all changes in synchronization.
* Rich collaboration and sharing experiences.
* Offline edits of synchronized files.
* Auto synchronization of the changes to the cloud and as soon as you are online.
