I am a HubSpot customer and business owner running an Exchange platform for MS Outlook, Office, etc. I and one other in our office work on a Mac. We purchased a Sales Pro + Marketing subscription and learned too late that the Outlook Desktop Sales Add-in tool will not work on a Mac. (Not unless you use the Office 365 version and switch to Office 365 hosting. Not an option for our little enterprise.) Not only do I have to manually bcc or forward correspondence to the HubSpot CRM … my prospects cannot “see” openings in my Outlook calendar. I am the principal closer of sales opportunities, which makes this issue critical for us. As far as your suggestion in the blue box to include “examples of other places or products who have this feature …” I guess my answer would be “everywhere else.”
