    Hi all

    We are experiencing a few random errors sending emails across the site. Most of the time it sends, but a few do not.

    The error is: “4.3.1 Insufficient system resources.”

    Website and server look fine, so not sure which resource its referring to.

    Redacted transcript:

  • Hi @castoruk,

    Are you sending using Office 365 or your own Exchange server?

    Office 365

    Hi @castoruk,

    That is unusual. How many emails are you sending on average?

    Are you using the Office 365 API extension, or just Authenticated SMTP?

    Kind Regards,
    Tim

    @castoruk

    This is a mail server error, contact your mail provider.

    Did a bit more digging and “4.3.1 Insufficient system resources” does appear to be a specific Exchange error.

    I’ve raised a call with the supplier. See what they come back with.

    Hi @castoruk,

    Yes, it is. If you have Office 365 direct from Microsoft, their service is noramlly quite good.

    Kind Regards,
    Tim
