OAuth2.0 Information - 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 announced that the disabling of Exchange Online SMTP AUTH Basic Authentication has been postponed. The vendor plans to announce the final removal date in the second half of 2027. However, it is worth noting that SMTP AUTH Basic Authentication will be disabled by default at the end of December 2026. For more details, refer to the official update on the “Updated Exchange Online SMTP AUTH Basic Authentication Deprecation Timeline” page.

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

After this date, 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.
