Outlook Desktop Updates

Developer Support APIs & Integrations
1

We are having issues with our Outlook desktop integration.

It crashes our outlook and causes major lag.

After contacting support, it seems like Hubspot is no longer doing any updates to this integration, only the Outlook Web.

We use Google workspace, so switching to Office 365 is not an option.

What can we do in this case?

Hi there,

I hear your frustration—Microsoft’s deprecation of the legacy Outlook desktop add-in (the HubSpot Sales COM add-in) has left a gap for Google Workspace customers who can’t simply switch to O365. Here are two paths you can take:

1. Short-Term Workaround: Gmail Integration in Desktop Gmail

Since you’re on Google Workspace, you can immediately switch to HubSpot’s Gmail add-on, which works in the Gmail web UI and in the desktop Gmail Progressive Web App:

  1. Install the HubSpot Sales Gmail add-on

    • Go to G Suite Marketplace → install the HubSpot Sales add-on.
    • It surfaces contact details, timeline, and logging tools in a right-hand pane.

  2. Use the Gmail PWA on desktop

    • In Chrome or Edge, open Gmail → click the menu ⋯ → Install Gmail.
    • You’ll get a native-app–like window (complete with the HubSpot sidebar).

This avoids Outlook entirely, restores your logging/tracking, and sidesteps the legacy add-in crash.

2. Mid/Long-Term Solution: Build a Custom Desktop Add-in

If your users must stay in Outlook desktop (e.g. they rely on specific Outlook-only workflows), the only sustainable route is a custom Office.js Add-in that calls HubSpot’s CRM API directly:

  1. Office.js Outlook add-in

    • Leverage the Office JavaScript API to build a pane that runs alongside Outlook desktop.
    • Use the Office.context.mailbox.item object to grab the current email or meeting context.

  2. HubSpot CRM API

    • Authenticate to HubSpot via a private app (access token).
    • Hit the Contacts, Engagements, and Timeline endpoints to pull or push data.

  3. Feature roadmap ideas

    • Real-time sidebar: show contact/company data, deal stage, last meeting notes.
    • One-click logging: push the current email or meeting as a Timeline event.
    • Custom actions: create tasks or follow-up workflows from within Outlook.

Let me know if this helps, or if you have any other questions!
