Delete your Office Document Cache - Microsoft Support
Office typically repairs the document cache files if it detects problems. If the cache files are corrupt and irreparable, deleting them allows Office to repair itself by replacing the corrupt files. Reboot and sync: This step is when Office repairs the cache. After the cache is repaired, a sync operation should clear up any "stuck" files.
