Stop other users files synchronization
Offline files has a single copy of cache where all the users offline enabled files are stored. This causes inconvenience to users even if they are not using offline files. Let’s say there are two users A and B. A has logged into the system and marks a network share for offline caching. Share is synced up and now A logs off and B logs in. Now offline files, from B’s login session, tries to sync the files which A has mad available offline. User B, who does not have any idea of this, will be prompted for credentials for accessing the network share. This keeps on popping up again and again and B have to face the trouble of closing synchronization window every time.
