SMTP Deprecation: Action Required for Some TMS/TMT Users
Microsoft is deprecating basic authentication for SMTP email services, starting March 1st, 2026 (with a final deprecation date of April 30, 2026), requiring a move to modern authentication methods.
These changes will affect certain Suite, TruckMate, Innovative, and TMT on-prem customers, and some TruckMate SaaS customers who use Microsoft 365 (formerly Office 365) to send emails from Trimble Transportation applications. To ensure uninterrupted email service, you will need to review the remediation guides below and take action to ensure continued email functionality. Remediations range from changing SMTP providers to upgrading your system. Due to the extensive changes needed in the application to accommodate these changes being made by Microsoft, it will not be possible to patch some older versions of the solution.
