Authentication Error - Issue with Sending Emails via sap-cloud-sdk/mail-client in SAP BTP CAP App

[Syed_Hussaini19]

Hi Experts,

I have been using the sap-cloud-sdk/mail-client in my SAP Business Technology Platform (BTP) Cloud Application Programming (CAP) application to send emails. This functionality has been working smoothly for several months without any issues. However, over the past few days, I’ve started encountering the following error when attempting to send emails:

I Observe that the email fails to send, and the error message ERROR (mail-client): Invalid login: 535 5.7.3  Authentication unsuccessful is displayed in the BAS console.

I have tried resetting the app password for both my Gmail and Outlook accounts, but the error persists.

Could you kindly assist me in troubleshooting and resolving this issue as soon as possible? This issue is affecting my ability to send emails, and I would appreciate any guidance or solutions you can provide.

Thank you for your support.

Regards,

Syed

The package has been deprecated. 

But for me it's working as before. Maybe mail provider has changed smth. (maybe 2FA auth?)
