Send Exchange Mail Message Error: E-mail address is formed incorrectly

Trying to send mail with Send Exchange Mail Message activity. I get following error

Source: Send Exchange Mail Message
Message: The e-mail address is formed incorrectly
Exception Type: Exchange Exception

I have tried more than one valid e-mail address as a “from” and “To” field. And also changed “User” fields e-mail address. EmailAutoDiscover is set to “true”.

Any idea what’s missing?

Problem solved!

Use Outlook mail Activies instead Exchange. Works fine!
