What is it?
Microsoft is deprecating Basic Authentication for Exchange Online in October 2022 and requiring Modern Authentication.
HubSpot’s Exchange integration uses Basic Authentication. However, our integration is designed for Exchange On-Premises instances, which are not affected by this change and will continue to be able to use Basic Authentication after October.
If you are an Exchange Online user and affected by this change, you can connect to HubSpot using our Outlook integration instead. Our Outlook integration is compatible with cloud hosted Exchange and uses OAuth, a form of Modern Authentication. You can reconnect your inbox using the Outlook integration at any time.
Which HubSpot features are impacted?
Connected personal inboxes using the Exchange integration.
If you are hosted with Exchange Online and using our Exchange integration, please reconnect your inbox using the Outlook integration. This will prevent your inbox from disconnecting in October when Microsoft revokes the Basic Authentication used to connect your inbox. At that point, you will no longer be able to reconnect with the Exchange integration and will be forced to connect with Outlook.
If you are unable to connect with Outlook, or unsure if you are an Exchange Online user, work with your local IT team.
Reminder: If you are hosted with Exchange On-Premises, no action is needed.
