Perch forms TLS version

  • Hi!

    I have been using Perch forms on our website for feedback/contact forms via Microsoft 365 SMTP Client Submission. It has been working like a dream until recently it just stopped working. I researched and contacted the support also and the solution is that Microsoft does not support TLS 1.2 or lower anymore.

    I checked that our website is using TLS 1.2 at the moment but our PHP version supports up to TLS 1.3, so is there some way to force Perch to use TLS 1.3 or is it Perch related at all? :)

    Kind regards,
