When you connect your Gmail inbox or your Office 365 inbox or calendar to HubSpot, you might encounter an error during the connection process. Learn about the root cause of these common errors and how to troubleshoot them.
Review the errors below if you encounter issues when connecting your Office 365 inbox or calendar to HubSpot.
If you're an IT resource, note that HubSpot uses Graph API for Microsoft 365 to integrate with your inbox. For the Office 365 calendar, HubSpot uses the Outlook REST API. HubSpot requires the following scopes in order to connect:
This error means that your Office 365 account does not have a mailbox for the email address you're trying to connect. For example, you may have an Office 365 account that you use for other products such as Word or Excel, but your email is hosted with a different email provider. You will need to choose the correct provider to connect your calendar or email.
You'll see this error in your HubSpot account as OFFICE_ERROR_REST_API_NOT_ENABLED_FOR_COMPONENT_SHARED_MAILBOX. This error can be caused in one of two ways:
You may see outlook_[string_of_characters]@outlook.com display instead of your email address when you connect an Office 365 inbox. This is because HubSpot does not support using a non Microsoft domain primary alias. This can causes issues with sending or syncing your emails from your connected inbox. Learn more about this issue and Microsoft's recommended solution.
If you see an "Interaction required" error when connecting your Office 365 inbox, it means your user needs access to the HubSpot Sales application in Azure AD. You may need to work with your email administrator to get access. Learn more assigning users to an application in Azure AD.
This error occurs when your IT administrator has configured restrictions on installing applications to your local Azure Active Directory environment.
To resolve this error so you can proceed to connect HubSpot's Office 365 integration, your admin can take one of the following approaches:
If your Google account is enrolled in Google's Advanced Protection Program, apps that require elevated access to Gmail and Google Drive are automatically blocked by default. For HubSpot's Gmail integration to work correctly, access is needed to read and write emails on your behalf, which Google classifies as high risk access.
To fix this issue and connect your inbox to HubSpot, you can contact your Google Workspace admin and have them add HubSpot to the list of trusted apps in your organization's Workspace settings. Learn how to set up a list of trusted apps in this Google Help Center article.
