Impact on Konica Minolta Products and Response due to Discontinuation of Basic Authentication for SMTP in Microsoft Exchange Online / Google Workspace


Thank you for your continued use of our products.

Microsoft has announced that Exchange Online will permanently remove support for Basic Authentication with Client Submission (SMTP AUTH) gradually, beginning on 1 March 2026.

Google has announced the end of support for less secure apps on 29 April 2025, taking effect on 1 May 2025. See their official update on the Google Workspace Updates page.

After these dates, sending emails via SMTP in Exchange Online or Gmail (Google Workspace) will require authentication using OAuth 2.0. We would like to inform you about the affected features of our products (MFPs/printers) and the schedule for releasing firmware updates which support OAuth 2.0 authentication.
