Script error: Send mail command failed

Dear Community,

I've been encountering an issue with the "Send email" function in FileMaker. Despite having recently updated to version 2024 on iOS Sonoma and using Mail as my default email client, I continue to receive an error message when attempting to send emails. I've tried troubleshooting various settings but haven't been able to resolve the problem.

I would appreciate any suggestions or advice from the community.

Thank you very much
Massimo

It's already checked.
The problem should be somewhere else.
I don't use outlook. Only Mail
