FormSnap3 problem - office 365 - mail will not send

1

Hi,
hopefully one worked through this before me and has a solution.
Host Europe migrated all the email accounts of one of my clients to MS 365.
I have a FormSnap3 form which should send the mails via smtp.
Checked all the FAQs etc - what are the correct settings?
I am using “smtp-mail.outlook.com” and port 587 and TLS - get a timeout from formsnap.
Also tried smtp.office365.com and port 465 - to no avail
Site is
Anmeldung Familienstellen Nürnberg
Thanks for tips and hints.
Tom

Correct Microsoft 365 SMTP Settings:

  • SMTP Server: smtp.office365.com
  • Port: 587
  • Encryption: STARTTLS (sometimes just called “TLS” in some UI)
  • Authentication: Required
  • Username: Full Microsoft 365 email address (e.g. user@yourdomain.com)
  • Password: Corresponding password (or App Password if MFA is enabled)

Microsoft 365 has dropped support for TLS versions 1.0 and 1.1, is FormSnap 3 perhaps using one of these versions?
