Problem

When using Office365 running on Mac OS X editing files residing on a UCS Samba share data loss might happen.

Solution

You need to disable preview per policy.
According to this thread you can use the following script to be run on your Mac OS X client:

 #!/bin/bash

# Casper PlistBuddy script to disable icon previews and the preview pane for enhanced 
# SMB share compatibility.  Should work with 10.9 through 10.11 (and beyond?)

# This script elaborates on some brilliant work from gumptiontech at the following link:
# http://gumptiontech.co.uk/2015/06/17/disable-mac-10-9-finder-thumbnail-preview-by-command/
#
# I've modified it to run as root and act on the currently logged in user.  Also added 
# additional lines to shut off the preview column in the column finder view, and to 
# disable .DS_Store creation on SMB shares.
#
# This should be run at user login, or by any other means while the target user is logged in.
