Issues Following Microsoft’s Deprecation of Legacy Exchange Tokens

Users may experience disruptions when using the Procore for Outlook add-in following Microsoft’s deprecation of legacy Exchange tokens. IT administrators concerned about this change may notice authentication errors if configurations still attempt to rely on deprecated methods.

Root Cause

Historically, some Outlook add-ins relied on legacy Exchange tokens for authentication. Procore has fully migrated the Procore for Outlook add-in to Microsoft Graph APIs, utilizing modern authentication approaches. Therefore, legacy Exchange tokens are no longer used.

• Modern Authentication:

  • The add-in is compatible with the latest Microsoft security standards. No legacy exceptions or "Extended Protection" overrides for legacy tokens are required for this app to function.

• Diagnosing Current Issues:

  • If you are seeing errors, they are likely related to specific Microsoft Graph permission blocks rather than token deprecation.

  • The application has been enhanced to show detailed error messages. Please capture a screenshot or video recording of the specific error code displayed so that the exact blocked scope or configuration error can be identified.
