OnePlaceDocs: open files with the system default handler based on file type (eg, if your system has Adobe Reader DC as it’s default PDF handler, then you would like OnePlaceDocs to always try to use that). The default is currently to try and do what SharePoint wants (if the override in CommonConfigLocal.xml is not present of course).

Now users have to change the open with setting for pdf to Adobe reader every day becauce the commonconfiglocal.xml is flushes because of roaming profile / UPS on RDS.
