I have used Trend Micro's Scan mail since Exchange 2000 and done well with it. We are not yet on Office 365, so I want to put something on my 2016 Hybrid install, and put Scan mail on. I started having issues with my Transport Service on the servers. Turns out the issue was that I moved the Transport queue off of the C drive to save space, on to another drive. I was being playful and put it on the M drive, for all you old Exchange administrators. :))
After applying CU 3, Transport Services would not start w/o me deleting the queue first. So I uninstalled Scan Mail, and still it would not start. I then moved the queue back to the "C" drive and all is good. So I am considering installing Scan Mail again and wanted to check and see what others are doing and if there is any reason not to.. feeling burned out from the first rodeo.
