Dialog window has to support add-ins for the New Mac UI
Our clients are using new Outlook design 16.42 (20101102)
Our Add-in uses functions: reply/replyAll/forward they open Dialog window(pop-up) and this window does not support add-ins.
This is really critical issue, because our clients use pinned panel of add-ins to complete their workflow.
Yes, it's shocking that MS releases new GUI features without backward compatibility for office addins. Please add this asap!
