Error 432 when sending emails via SMTP from BPM by Office365

  • 1.  Error 432 when sending emails via SMTP from BPM by Office365

    Posted Fri March 01, 2024 02:18 PM

    Hi;

    O365 has a limit that only up to 3 concurrent connections can be used at the same time. If the application tries to send more than 3 messages at the same time, using multiple connections, each connection will receive the aforementioned error "432 4.3.2 STOREDRV.ClientSubmit; sender thread limit exceeded".

    My question, is how other companies have solved this problem?
    What actions at the BPM level can we apply?

    Thank's
