SMTP Error NAV 2016

Posted on by 2
 Hello,
 
The following error is occurring when testing email connection:
 
//
 
The firewall settings are allowed.
 
I understand this could be fixed by a CU update (https://cloudblogs.microsoft.com/dynamics365/no-audience/2018/12/06/how-to-get-earlier-versions-of-the-dynamics-nav-development-environment-to-work-with-tls-1-2/) but this really is not feasible since we are upgrading them anyway to BC in a few weeks.
 
Is there no other setting or configuration that is lacking, which could be causing this error?
 
Thanks,

    if the smtp was working fine and just broke. check the following
     
    if anyone changes the credentials
    if modern authentication needs to be used instead of basic
    if the TLS is set up correctly
     
    seek someone from someone familiar with the clouds/server side to check/fix the settings.
