The Google Calendar and Outlook Calendar sync with HubSpot allows you to simultaneously log a meeting in your CRM, create a calendar event for that meeting, and send invites to meeting guests. Additionally, if you create a meeting event in Google Calendar or in Outlook Calendar with a HubSpot contact, the event will appear on their contact record timeline.
To use your calendar with the HubSpot meetings tool, refer to this article instead.

- You'll be redirected to Google to sign in or choose a Google account if you have multiple accounts.

Schedule a meeting in HubSpot
After you’ve connected your Google Calendar or Outlook Calendar, navigate to contacts, companies, deals, or tickets. In the left panel, click the Meet icon to create a meeting event. In the window that opens at the bottom of your screen, enter you meeting details. When your meeting is created, a corresponding event will be added to your Google Calendar or Outlook Calendar and the contact will receive a meeting invitation.

Please note: deleting a meeting in HubSpot will not remove the event from Google Calendar or Outlook Calendar.
Schedule a meeting in Google Calendar or Outlook Calendar
If you create a meeting in Google Calendar or Outlook Calendar and include a guest that is a contact in your HubSpot account, the meeting will appear on their timeline. The same is true if a contact in HubSpot invites you to a meeting; the meeting will appear on the contact's timeline. 
If you edit or delete the event in your calendar, the updates will also appear in the meeting on the contact timeline automatically.
- When a meeting is created from your connected calendar, the meeting will only log on the timeline of contacts that already exist in your HubSpot account. HubSpot will not automatically create contact records if the guests do not already exist in your HubSpot account.
- For the meeting to appear in your contact's timeline, the guest must be using the same email address in their contact record's Email property.
- HubSpot automatically prevents any events from being added for members of your organization based on email domain (your portal’s target and connected domains), and existing users.
- Any events created prior to the integration will not be synced to HubSpot, even if guests in such events exist as a contact in your HubSpot account and have the same email address in the Email property. Only events created in Gmail and Office 365 while the integration is active will be synced to the contact's timeline.
- For recurring meetings, HubSpot will only sync the first event in the series. If another event in the series changes, or attendee response changes, the updated event will sync to HubSpot. For example, if someone cancels one particular week for a regular weekly meeting, it will trigger that week's event to sync to HubSpot.
- All day events will not be synced to HubSpot.
- HubSpot's calendar sync does not sync private calendar events to your HubSpot account.
