End-of-Support Platforms

The Exchange Online (EWS) (previously Office 365 Mail) Target uses the Basic Authentication method for Exchange Web Services (EWS), which is marked for retirement by Microsoft on October 1st, 2022. Existing scans for Microsoft 365 - Exchange Online (EWS) may start to fail once Basic Authentication access is disabled for Exchange Web Services (EWS).

To continue scanning Exchange Online, you are recommended to use the Exchange Online (Graph) protocol which uses the more secure application permissions workflow for authentication and authorization. The recommended Exchange Online (Graph) protocol also simplifies compliance management by allowing you to identify, remediate and report results according to predefined Groups in your organization's Exchange Online mail environment.
