I had to call Microsoft and revert back to Office 2013 because of the eMails posted in the Google eMail account were not sticking. Apparently this is a known problem as Microsoft had no problem rolling me back.
When I was in the Microsoft forum, others posted issues with Exchange. I personally was not having any Exchange issues that I noticed, so this is just a heads up there.
