Error retrying to send an email to valid recipient error (reset password functionality)
I have a testUser inside a userGroup inside myOrganization
I configured SMTP Mail Server for Outbound Messaging (using outlook)
To test Service I use SendMessage method. It works fine

My problem comes after using reset password inside myOrganization login form.
I get the following messages:
| Warn | User [testUser] is a member of [myOrganization] and has confirmed their personal information - sending reset email | SuperUser | S.c.t.s.a.ThingworxFormAuthenticator | https-jsse-nio-8443-exec-56 |
then
| Error | Error sending email to the following invalid addresses: null | S.c.t.t.m.MailThing | https-jsse-nio-8443-exec-56 |
and finally
| Error retrying to send an email to valid recipients after invalid ones caused a failure, or failure to send an error email about this event: 501 5.1.7 Invalid address_ | S.c.t.t.m.MailThing | https-jsse-nio-8443-exec-56 |
I'm not understanding the error or how to solve it, the email address is correct as I have confirmed it, it seems the email address is getting lost in some part of the function, Could you please give more detail on those messages and a workaround?
