Microsoft Outlook integration now supports NAA

by Product Marketing

June 16, 2025

To align with Microsoft’s updated security requirements, we’re migrating to nested app authentication (NAA) the week of June 16, 2025.

Why are we migrating: Microsoft will no longer support legacy user tokens later this year. This migration to NAA  ensures uninterrupted access to Microsoft services and provides a more secure, modern authentication experience for users.

What does this mean for you: All users will need to reauthenticate their Outlook integration the week of June 16, 2025. More information available at this Help Article.
