Update:
No go on the 2016 for my coworkers laptop. Tried 32/64 M$ office 2016, tried the office 365 variation of 2016. Installing avaya plugin always netted 0KB for install.
Not wanting to go through the hassle of restoring, upgrading and reloading all personal data; I decided to install 2013 64bit, which worked immediately.
I know some Outlook2016's are working, my guess is to check to see if you have a previous install of Office or outlook, it may be piggybacking the install for 2016.
