    Hello,

    On a newly installed SI2026 system, I successfully emailed the first 25 invoices. However, the 26th invoice (and any new or previously sent ones) now fails to send.

    The error message displayed is: “One or more required fields is missing.”
    No settings have been changed during this period.

    The SMTP server used is mail.smtp2go.com. I also tried two other SMTP servers, but all give the same error.

    Thank you in advance for your help.

    Best regards.

    Hello,

    The problem is solved, I think!

    The first 25 invoices were sent without a message.
    As soon as I added a message, they started sending again.

    Thank you.
