Error retrying to send an email to valid recipient error (reset password functionality)

[EM_9923519]

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?

Hello, I've been trying to make it work but I am not able to do so, I double checked the configuration for

Mail server (valid email, send message work fine, no reply, reply and error mails are correct too), organization, user information (fisrtName, lastName, emailAddress) and that user is part of composer group. However I am Still getting the message:

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_

Normally we create a thing that extends MailServer, so do you check these configurations(Mail Account User,Default From Field,No-Reply Address,Reply Address,Error Address) of this thing instead of the MailServer template?

[EM_9923519]

There is this Mail Server Thing template

I extended it using myEmailServer:

Then in organization Password Reset Mail Server 

I added myEmailServer

Still not able to solve the issue

Yes I double checked them, I also tested the send email function to test functionality and is working

There must be a little detail I am missing
