I am in the midst of migrating all workstation to Windows 10 Pro from Windows 7 Pro. Our Domain Controller is also a File Server running on Windows 2012 R2. All staff's Desktop and My Documents are redirected to the file server \\servername\home$\%username%. Roaming profiles and offline files are enabled on all users. So far we have no issues with this setup for windows 7 users. However when tested on Windows 10 Pro machine, a weird behavior occurs.

Whenever a user edit and save an office file offline (at home), and connect back to the network (the following day), they will always get file sync conflict and .tmp file is created in that folder. See picture below.

When i check in the file server, the original file has been renamed to ~RFxxxxxxx.TMP suffix (or maybe the original file was deleted and then the .tmp file was created).

Because of this behavior, i am given 2 option to resolve this conflict. 1) Keep this version and copy it to the other location 2)Delete the version in both location. See below:

Of course i will choose option 1 which is to keep this version and copy it to the other location. Doing so, the latest copy of the file will be copied to the file server BUT the .tmp is still there. As such i have to manually delete the .tmp file. 

Imagine doing this everyday for notebook users. It is quite annoying.

Any help will be appreciated.
