I am using SharePoint 2016 site (external), For the one of the list I am using only one line workflow logic that is send email,
and in TO area I have put external user mail id, in CC it is mine. .

When I start the workflow manually from item, I can see workflow started and completed successfully, But mail is not going to external user, where as I received the mail
Please help refer below screenshots

Have you checked the SMTP logs on your mail server to see if it is rejecting it?

You should speak to your mail administrator regarding the SMTP logs. How you check those depends on the mail server in use that you're relaying the SharePoint mail to.

Hi @sns ,

Please refer to this article to check the SMTP log:

https://portal.databasemart.com/kb/a498/how-to-check-smtp-logs-in-windows-server-iis.aspx

More information on debugging a SharePoint workflow with Fiddler:

https://learn.microsoft.com/en-us/sharepoint/dev/general-development/debugging-sharepoint-server-workflows#walkthrough-debugging-a-sharepoint-workflow-with-fiddler

Also check the Event log for any clues.

Hi Wang,
is there any link to download official version of fiddler? please share me the link as well to download

and we have 2 WFE and 1 APP 2016 SharePoint servers, IIS 10 is available
I don't see IIS 6, now do I need to install this one?
I mean SMTP configured IIS is not there, how to get it?
Do I need to check in SharePoint server or SMTP server?

when workflow failed to send mail is it coming under incoming email or outgoing email?
it is outgoing email, correct? so in that case how do we check SMTP logs?

Hi @sns ,

Fiddler Download link: https://www.telerik.com/download/fiddler

No, IIS 6 just a sample, go to SMTP server to track the log.

Yes it is outgoing email.

This is assuming the OP is using IIS SMTP. That is likely not the case as this would be an atypical setup in a Microsoft environment (i.e. Exchange is more likely).

Hi Wang and Seward,

I asked SMTP exchange team, they have asked for below details. Below is the response from SMTP team
You will need to ask the user to send a test email to the external email address from a SMTP workflow or something like that. We need more data to be able to trace the email.
IS the user getting an email stating that it was not delivered or something like that? We would need the MSGID, header, from and to etc to do a trace. Please check if an email can be sent from the server or something like that

When workflow is showing completed with no errors, How could I share information to respective team. Please help
