Upgraded to Outlook 2016 (x86) on Windows 10 and Spambayes has continued working smoothly. This is a great add-in - thanks guys!
Doesn't work well with Outlook 2007
It's working OK so far on a newish 64-bit Win-7 desktop as of 5/14. It is slightly slow and has a clunky (antique) UI feel but seems to get the job done with adequate user options but not too many options. To make it work I hade to install in a non default directory, C:/spambayes and then upgrade gocr049.exe which was crashing Google will find comments on both these issues.
