Everything You Need to Know About HubSpot Ending Support for the VSTO Add-On

Hey Community,


You may have seen the announcement about HubSpot ending support for the Outlook VSTO Sales Extension.

The tl;dr for why we’re sunsetting this is that Microsoft has moved away from the VSTO add-in framework entirely. This announcement from Microsoft impacts the HubSpot Sales VSTO Add-In along with any other VSTO Add-In. 


Going forward HubSpot customers should use the Office 365 add-in to integrate HubSpot’s sales functionality into their email. As Microsoft extends support to additional inbox providers (e.g. IMAP, POP3, Yahoo, etc.), customers can move to the new Outlook for Windows and leverage the O365 add-in.


At HubSpot Community, we want to support you through this transition. Below you will find a list of resources on this Microsoft release and next steps:
