Microsoft is deprecating Basic Authentication in Exchange Online beginning 1st October 2022.

This is to fortify the security of your apps and data to protect against attackers that capture user credentials stored or saved on your user’s device. Basic authentication is an outdated industry standard, and sometimes makes enforcing multifactor authentication (MFA) complex.

What this means for you?

Beginning 1st October 2022, client apps using the protocols below will not be able to connect to Exchange Online using Basic Authentication:

  • EWS (Exchange Web Services).
  • EAS (Exchange ActiveSync).
  • RPS (Remote PowerShell).
  • Offline Address Book (OAB).
  • Outlook for Windows and Mac.

 

Next Steps

  1. Switch to Modern Authentication (OAuth 2.0 token-based authorisation) before October 1, 2022 to get uninterrupted service and provide better and more effective user authentication.
  2. Reach out to me if you need assistance with determining if your systems will be impacted. Our team can help you review and advice for only $500. (Valid until 30th September 2022 and subject to availability. First in, first served).
