Custom engineered Calls & Messaging integration

Microsoft Outlook & HubSpot integration

Custom engineered for your business by SpotDev's accredited developers

Connect Microsoft Outlook and Exchange Online to HubSpot so shared mailboxes, individual email and calendar events are logged against the right contact and deal by rule, using Microsoft Graph rather than each user's add-in.

  • 2 to 4 weeks typical turnaround
  • £2.5k-£6k typical investment
  • OAuth 2.0

Why connect Microsoft Outlook to HubSpot

HubSpot's Office 365 add-in logs and tracks email when the task pane is open, and a connected inbox handles a user's own mail and calendar. HubSpot also states that Microsoft 365 shared mailboxes are not supported as individual connected inboxes, which is exactly where sales@, info@ and accounts@ live.

  • Shared mailbox conversations never reach the contact timeline unless someone forwards them
  • Logging relies on the add-in being open at send time, so the record depends on habit
  • Calendar events booked in Outlook by assistants or from other systems do not become HubSpot meetings
  • Microsoft Graph gives an application access to primary and shared mailboxes, calendars and contacts, with change notifications for new messages and events

What you can do with Microsoft Outlook and HubSpot

The integration uses Microsoft Graph with application permissions granted by your Microsoft 365 admin and writes activity to HubSpot under your rules.

  • Log every message in a shared mailbox to the matching contact and open deal or ticket, including attachments, as it arrives
  • Match inbound email by sender domain to the company when no contact exists, and create the contact with the right owner
  • Mirror Outlook calendar events to HubSpot meetings and back, so reschedules and cancellations show on the deal
  • Exclude internal, personal and marked-private mail by rule so only customer conversations are stored

Microsoft Outlook & HubSpot integration: FAQs

Does Outlook have an API that HubSpot can use?
Yes. Microsoft Graph is the REST API for Microsoft 365, including Outlook mail, calendar and contacts. It supports primary and shared mailboxes and can send change notifications when messages, events or contacts change, so a service reacts as mail arrives rather than polling.
Is the HubSpot Sales Office 365 add-in enough?
For reps logging their own email, usually. It tracks opens, logs email and attachments to contact, company, deal and ticket records and works in Outlook for Windows, Mac and the web. Its logging applies only when the task pane is open, and HubSpot does not support shared mailboxes as individual connected inboxes, which is where a custom build comes in.
How long does an Outlook HubSpot integration take?
Usually 2 to 4 weeks, including admin consent in Microsoft Entra and agreeing the logging rules.
How much does an Outlook HubSpot integration cost?
Typically £2.5k-£6k. The count of shared mailboxes and whether two-way calendar sync is included set the price.
