Incident: Microsoft Outlook and Related Connectors – Connection Issues

Starting at around 7:30 PM PDT on August 31, 2025, until around 5:35 AM PDT on September 1, 2025, some users were unable to authenticate their Outlook account when using the Microsoft Outlook Email steps in Workflow Builder, specifically the "Send an email" step. This may have presented as a "Something went wrong" page with an "access_token_exchange_failed" error.A backend authentication configuration was attempting to use incorrect credentials when initiating the OAuth flow, which resulted in the errors. We conducted a routine update to correct the credentials, resolving the issue for all users.
