  • My questions for you are

    1. Can you telnet to the Exchange server on the problem server?

    2. Do you have a receive connector that accept from this problem server

    3. Can you see if it is in the message queue? 

    4. Do you have a valid mailbox in the Exchange server to accept the email?

    5. Is there a size limit on Exchange. 

    More info like the setup would be helpful.

  • Hi,

    Please tell us more about custom work flow, that will be helpful for us to understand your problem better.

    For your IIS log, just no connection between your exchange and recipients. Does this issue occur for internal messages?

    And do you create a send connector via smart host? Make sure smart host side is no problem.


    Best Regards,

    Thanks for the insight you raise some good questions and test for us to run. Can you offer a little insight on where to run the five test? My guess is central administration but I'm not completely sure. Once we run them I will let you know.

    Sure, the custom work flow was created in SharePoint Designer 2010 and its designed to send an email to a few people when a user adds an item to a custom list also created in SharePoint designer 2010. Another email is sent when an item in a list is updated. 

    The email contains a few custom lookup values from a form the user filled out. 

    How do I create a send connector via smart host? 

    Also, how do I verify that there is no connection between the exchange and my recipients? I don' think the issue occurs for internal messages. We were able to statically send an email from the server to one of the people we would like the emails to dynamically go to when an item is added.

    1. Can you telnet to the Exchange server on the problem server?
        - on the problem server via command prompt. If telnet is not instead then go to server features and install the         telnet client.
    2. Do you have a receive connector that accept from this problem server
         On the Exchange server go to Server Config -> hub Transport -> default connector
    3. Can you see if it is in the message queue? 
        On Exchange, go to tools -> queue viewer
    4. Do you have a valid mailbox in the Exchange server to accept the email?
        On Exchange -> Recipient config -> mailboxes and search for the mailbox that you use to send as. 
    5. Is there a size limit on Exchange. 

         On Exchange, go to Org config ->   Hub Transport -> global settings -> Transport Setting properties

         On Exchange, go to Server config ->   Hub Transport -> default connector -> General
