SharePoint Outgoing Email Error 160003 and 10060 from ULS

Question

SharePoint Outgoing Email Error 160003 and 10060 from ULS

Marc Cumos 126

All,

Been a while since I've been on the forum. Hope everyone is doing well.
Run into a strange problem this weekend with outgoing email in the farm. All workflows are giving errors since late Friday stating
"The e-mail message cannot be sent. Make sure the outgoing e-mail settings for the server are configured correctly."

I haven't changed these settings in years since the farm was stood up.

I checked the ULS logs and saw these two errors

the smtp server is outside the farm. Port 25 is open as well.

Any suggestions would be appreciated!

The SMTP Connect error 10060 indicates that there is a connectivity problem to your SMT P Server. You may need to check the connectivity between your server and SMTP host.

You may use telnet command from the SharePoint Server(s) to ensure that there is connectivity to SMTP Server.

@Sreeju Nair I installed the telnet feature and ran the commands in the learn.microsoft link you provided. I received the email at the end of the telnet session as well.
I tested the workflows again and got the same error. Ran telnet on both wfe on the farm
@Xuyan Ding - MSFT - I also ran the nslookup and tracert from the our sp farm wfe, and got the expected results.

Triple checked that the central admin has the correct smtp fqdn in the outgoing email settings.

@Marc Cumos Mostly this might be due to the authentication, I believe.

Can you try sending the Mail from powershell.

$dict = new-object System.collections.specialized.stringdictionary  
  
// recipient's Email Address  
  
$dict .add("to","******@gmail.com")  
  
// sender: you can put anything that you want to visible in the email  
  
$dict .add("from","outsender@sharepoint.local")  
  
$dict .add("Subject","sample subject")  
  
// this is any existing sp web url  
  
$web = get-spweb "http://4587wfe2013:5003"  
  
$body = "This is our body codes in it."  
  
[Microsoft.SharePoint.Utilities.SPUtility]::SendEmail($web,$sd,$body)

Also refer the blog to see the details: http://melick-rajee.blogspot.com/2014/08/an-error-occurred-while-talking-to-smtp.html

Also in your mail server, make sure you have enabled the mail server to accept anonymous relay from the SharePoint servers. You might need to add all SharePoint servers IP to SMTP relay address.

Hi @Marc Cumos ,

As a supplement:

Have you tried testing the SMTP functionality with telnet as sreejukg said? You can also try using PowerShell to send emails from SharePoint.
Make sure that nlsookup and tracert show the correct information from the SharePoint server to your SMTP server hostname.
Check for firewall issues inbound to the SMTP server or outbound to the SharePoint server.

Hi @Marc Cumos ,

Have you tried the PowerShell code provided by sreejukg to send the mail, is the mail sent successfully? Also have you checked your firewall?
