Unable to send email from NAV SMTP

Dear Team, 

Am facing technical issue while sending/testing SMTP email setup on Microsoft Dynamic NAV [Version details below ]

The issue facing/found that, When we send test email to deferent email ID or domain, the email getting error "Mailbox Unavailable/no permission to send".

Eg. : If I send email test1@mydomain.com to test1@mydomain.com - working fine. 

If i send email from  test1@mydomain.com to  test2@mydomain.com - getting permission error/mailbox unavailable. 
my smtp server is smtp.bizmail.yahoo.com. 

In order to sort out the issue, i have tested below scenarios. 

Deployed internal Microsoft SMTP relay server and outbound connection smtp.bizmail.yahoo.com. When we test NAV with internal relay server, the email are transmitting from NAV to relay server. 

the email are sending both above eg. scenario. but test2@mydomain.com are greeting failed on SMTP relay server [inside the Badami Folder ]. 
in the same time, i have tested SMTP tester tool to send email by using same internal relay server. all test email to same domain and external domains are works fine. 


In addition to internal relay server, i have used  on premise Microsoft Exchange server SMTP, the result is above same like above result.

So, I conclude that, the MS NAV not sending emails to outside domain or even internal email other than same email ID in atuh. 

Can anyone advise what could be issue on NAC side, is there extra setting should i followed on NAV. 


MS Dynamic Version : 2016
Version W1 9.00
9.0.47042.0

    Thanks for your reply,

    My email services on Yahoo, don't have service on Office 365.

    The exchange server i used it testing not available for me for all the time user, if i have that can configure send as permission to check functionality.

    Could you please refer any configuration SMTP for Dynamic AV.

    I used below option only,

    Send a test email using System administration > Setup > Email > Email parameters > Test email.

    Hello,

    As always with these scenario's, there is not much you can configure from Dynamics NAV side. As the error mentioned: permissions error or mailbox not available. This means that this is an SMTP server issue.

    Best is to use:

    smtp.office365.com

    587

    UseSsl

    The mailboxes must be licensed with an Exchange Online license.

    Thanks.
