My customer wants to use 2-factor authentication because of an email problem.  When I turn it on for me. I get the following error:


535.5.7.139 Authentication unsuccessful, the request did not meet the criteria to be authenticated successfully.

It using Outlook in Office365 on the web.


The application is currently running in PB2019 -- I did test upgrade it to PB2025 and get the same results.


I cut a bunch of stuff out of the function but I think I left the relevant parts.


Any ideas?


n_pbnismtp ln_smtp


// set message properties
ln_smtp.SetSenderEmail(ls_sender)
ln_smtp.SetRecipientEmail(ls_recipient)
ln_smtp.SetBCCRecipientEmail(ls_sender)
ln_smtp.SetSubject(as_subject)
ln_smtp.SetMessage(ls_body, lb_html)
 
// send the email


Try
 
 ll_status = ln_smtp.Send()


 catch ( NullObjectError noe )
 f_message_box("Null Object Exception", noe.getMessage())
 Return -1
 catch ( PBXRuntimeError pbxre )
 f_message_box("PBX Exception", pbxre.getMessage())
 Return -2
 catch ( Throwable oe )
 f_message_box("Other Exception", oe.getMessage())
 Return -3
 finally
 If ll_status = 1 Then
 f_message_box("works", "Message Sent!")
 Else
 ls_errmsg = ln_smtp.GetLastErrorMessage()
 f_message_box( "Mail Error: " + String(ll_status), ls_errmsg)
 Return -4
 End If
end try
