Hi all.
Can anyone help me to know where this error comes from?
It only happens in production, I think it is with some specific email that they use in Production.
But I can’t replicate it in QA or Dev, and I can’t find profitable information.

Error Log:
d_arrow_down Raw message: Object

This error is coming from the “Send Exchange Mail Message”. The issue is that Office 365 thinks that one or more recipient isn’t valid. Please check that the email recipients all exist. It is likely just a typo in someones email.

Hi, thanks, yes, we check all emails recipients exist and are valids… This is the reason for why i dont understand the error.

But i will be check again and others possible options…
