In testing PB2019 normal users programs hung when sending mail and the task had to be stopped. This did not happen for admin users. The mail was sent and the hang occurred on mSes.mailLogoff(). I just commented it out and all works fine. In the past if outlook was not running, mail would start it and then this would close it but that does not work anymore so I don't the the logoff is necessary. I also suspect Symantec but could not get any confirmation from network guy. Everyone is Win10, Outlook 2013.
