Port 587

    Question

  • When I send an email to an account on my exchange 03 server from an external email address that requires authentication and uses port 587 I don't get the email on the exchange server account. I receive from a different accout that uses port 25 just fine. What do I do?

  • This is a known issue with Outlook Express on Windows XP and Windows Server 2003 and Windows Mail on Windows Visa. The fix is here:

    A mail program cannot connect to an Exchange Server 2007 server by using SSL over SMTP port 587

    Alternatively you could use Mozilla Thunderbird

  • Please read the articles provided by the friends above. Port 587 is used for internal user to submit email in most situation. I guess you mean your mail client can’t connect to Exchange via port 587? What’s your mail client?

    I actually submitted this to Microsoft all those years ago. I was soooo glad when the fix finally came out!

  • ok, in exchange server 2007, does in this case the Outlook client connected to the HT server using port 587 instead of Dynamic port (> 1024 until 65525 <) ?
