Email in a SESC-created folder is not processed and removed to the Deleted Items folder.

This article contains the steps to troubleshoot this issue.  It does not provide root cause analysis for why an item below may not be functioning.  If you locate error messages or event IDs that may indicate a potential problem use them to search in the knowledgebase for possible root causes.

  • Check the SESC console for "failed" submissions.

1. Open the SESC console.  On the top of the screen is a Failed counter.  If this is non-zero the submissions may not be processed by the Symantec threat center.
2. Open the SESC debug log (default location is C:\Program Files\Symantec\SESC\1.0\Logs\log.txt) and look for errors.  An example of a submission error is the following:

[::]2012-05-02 09:12:29,154, [25], ERROR, Symantec.Submission.Common.HTTPClient.HttpPostRequest, Exception caught while getting HTTP response.

 System.Net.WebException: The remote server returned an error: (412) Precondition Failed.
   at System.Net.HttpWebRequest.GetResponse()
   at Symantec.Submission.Common.HTTPClient.HttpPostRequest.PostRequest()

3. If there are errors search the Symantec knowledgebase for errors relating to the message.

  • Check that the SESC web site is running.

1. Open the IIS Manager control panel by using Start Menu|Internet Information Services (IIS) Manager.
2. Click on <server>|Sites in the Connections pane.
3. Ensure that the site Symantec Email Submission Client is in the Started status.

  • Check that the SESC web site is accessible from the Exchange CAS server.

1. From the Exchange CAS server open a browser and go to this URL:


NOTE:  Replace <sesccomputer> with the name of the computer where SESC is installed.  The following is an example where SESC is installed on the computer with name sesccomp01-na:


IP addresses and fully qualified domain names are acceptable as well.

2. The browser may prompt for domain credentials.  Enter the SESC service account credentials.

See the attached screenshot for what the result should be.

  • Check that SESC has an Exchange Web Services (EWS) subscription for the user.

2. Open the System Update pane.
3. Select the appropriate Exchange servers from the Select Servers tree.
4. Click the Update button.
