HubSpot Gmail or Outlook Inbox Disconnected
Workaround available Web, Gmail, Outlook Updated November 13, 2026Based on 4 user reportsHow we research
Quick answer
Reconnect the inbox in Settings, then fix the underlying Google or Microsoft 365 permission. Outlook drops usually point to licensing, Graph API access or admin consent problems.
Most likely fix: Reconnect and check status
How to fix it
Try these in order — the most common fix is first.
1. Reconnect and check status
- Go to Settings > General > Email (inbox connection) and reconnect
- Check status.hubspot.com for incidents; a Microsoft outage in March 2025 forced reconnects

- Confirm the mailbox is in Exchange Online with an active license
- Re-grant HubSpot's Graph API permissions in Microsoft Entra ID
- Assign the user to the HubSpot Sales app
- Enable user consent or the admin consent workflow for 'Need admin approval'
- Reconnect with the Microsoft Outlook method and monitor 24-48 hours
Did this fix it?3. Hybrid or migrating mailboxes
- Check MX records in MX Toolbox
- If not hosted by Office 365, connect via IMAP or Exchange instead
Did this fix it?4. Google Workspace
- Ask your Workspace admin to add HubSpot to trusted apps (required for Advanced Protection accounts)
- Community advice: revoke HubSpot in your Google account permissions, then reconnect and grant all permissions
Did this fix it?
Symptoms
The connected inbox shows as disconnected, emails stop logging, sequences stop sending, or you see 'Outlook mailbox is not enabled for REST API access'.
Why it happens

- Tenant blocks HubSpot's Graph API access or requires admin approval
- User not assigned to the HubSpot Sales app in Azure AD
- Google Advanced Protection blocks the connection
- Upstream provider outage forcing mass reconnects
