Outlook COM Add-Ins Nearing the End of the Line

A recent Practical365.com article got me thinking about the Report Message and Report Phishing Outlook add-ins and how the new Monarch client can’t use COM add-ins. Microsoft is busily updating its add-ins to move away from COM to embrace the new approach based on HTML and JavaScript. If Microsoft is taking this action, I hope the same is happening in ISVs and in-house development teams who generated COM add-ins in the past.
