@carloscunha this is what the recipient receives. So looking at the email from the sent items of the original sender is the full email and occasionally, the recipient will just receive the text "undefined" in the email body.

HI
Does this appear in the body of the email or in the sender's field?

Hi there,

I’m experiencing issues with a mailbox, the user composes and sends the email as normal, but for the second time the recipient has just received an email saying “undefined” as opposed to the original email.

Is this a bug?
