I’m would still suggest that this is the issue I mentioned as Jan 06.

Office Upload Center may interfere with saving to Cryptomator drives

Please note that because of Cryptomator providing the virtual drive via WebDAV, Office Upload Center 2010 will assume Cryptomator files are on a network drive. If you have “paused uploads”, it will silently fail to save files to Cryptomator and they will remain in Office cache unencrypted instead. E.g., this resulted in Excel displaying a small message on the application status bar when trying to save to Cryptomator drive while uploads paused. But exiting Excel doesn’t show any dialog boxes or …

But responded, that there are no cached files. Now you have cached files. Have you tried the solution above?
