coming straight to the point, I tried using the Python win32com demo outlookAddin.py and it was working fine with Outlook 2010.
I upgraded to Outlook 2016 and since then the outlookAddin.py is still working however the addin msoControlButton that it is adding in the Add-ins ribbon has no caption.
Can anyone please help me understand how to resolve this. The code is by default available to anyone installed win32com but I am still giving it below for ready reference.
