I am running Windows 7 Pro 64 on a laptop and have a drive mapped to a file server on the network. I set a folder on that drive to be "Always available" and it is fully synced with no conflicts. I am connected to the network, so the folder's "Offline status" says "Online". I then edit a Word document within that folder and save and close it. Now, other users on the network say the file is no longer there, but I still see the file from my laptop. I view properties on the file and on the Offline Files tab it says "This file is offline with unsynced changes." (Before I modified the file, this same place said "This file is online.") I then to go Sync Center and do a Sync All, and it reports 2 conflicts. One says that the Word document was deleted from the server and modified on my laptop. The other says a .tmp file was deleted from my laptop and modified on the server. But why did this file even become offline if I was online at the time? I never disconnected from the network during the entire process. Every time I modify a Word document on this server while online, I need to manually sync and then resolve the conflicts myself or the file will be missing to other users. This is incredibly frustrating.

Hi, I do not suggest you edit an office file when you are online. Since one temporal file will be created when office file being opened, it is also synchronized when you editing, the office file on your laptop will not be synchronized successfully after editing. You'd better edit the office files in other drives and drag to the mapped drive. Ivan-Liu TechNet Community Support
