Service contribution: Disabling of basic authentication Exchange Online

Background

Starting October 1, 2022, Microsoft will begin disabling basic authentication for certain protocols in Exchange Online. Affected protocols include Exchange Online for Exchange ActiveSync (EAS), POP/IMAP, Remote PowerShell, Exchange Web Services (EWS), Offline Address Book (OAB), Outlook for Windows/Mac. For more details, visit this Microsoft website.

Impact

Due to changes in Microsoft's advanced security policies for TA Triumph-Adler products, OAuth 2.0 authentication will be required to receive email using Microsoft Exchange Online starting October 1, 2022. If OAuth 2.0 authentication is not supported, the following issues may occur:

  • Multifunctional Systems (MFP) & Printers: the print function for receiving e-mail will not be available. Sending e-mails is still possible
  • TA Capture Manager: the email receiving function will not be available. Sending e-mails is still possible

Workaround for customers

Microsoft announced in September 2022 that basic authentication can be reactivated once per protocol: https://techcommunity.microsoft.com/t5/exchange-team-blog/basic-authentication-deprecation-in-exchange-online-september/ba-p/3609437

The enabled protocols will remain enabled for Basic Authentication until the end of December 2022. However, in the first week of January 2023, these protocols will be permanently deactivated for use with Basic Authentication - there will then be no way to reactivate them.

If customers do not want basic authentication to be disabled for a specific protocol in October, Azure Tenant administrators can use the Microsoft 365 Admin Center self-service diagnostics at the following link: https://aka.ms/PillarEXOBasicAuth

Measures taken by TA Triumph-Adler

  • Multifunctional Systems (MFP) & Printers: a firmware update for OAuth 2.0 for current models will be successively deployed starting January 2023
  • TA Capture Manager: Release of a software update for OAuth 2.0 expected end of October 2022
