IMPORTANT NOTICE: Desktop Sync has been out of support since December 31, 2019. As it is approaching its End of Life on April 30th, 2024, we strongly encourage users to transition to our Desktop App as soon as possible. If you would like to learn more about the differences between these products, see how Desktop Sync and Desktop App compare.
If a user is editing via Desktop Sync on a file they will be locked out of uploading any saves on the file when someone else edits the file using the Microsoft Office Online integration. Once the Microsoft Office Online integration unlocks the file, Desktop Sync will be able to save files back to the cloud. A conflict will be created by the Desktop Sync user.
