Event ID 5120 is logged when e-mail messages are processed by Small Business Server 2003 (837370)
The information in this article applies to:
- Microsoft Windows Small Business Server 2003, Standard Edition
- Microsoft Windows Small Business Server 2003, Premium Edition
SYMPTOMSWhen the Exchange Server 2003 component of Microsoft Windows Small Business Server 2003 processes incoming and outgoing e-mail messages that have attachments, the following event may be logged in the application log on the Small Business 2003 computer:
Event Type: Error
Event Source: SmallBusinessServer
Event Category: None
Event ID: 5120
Date: 1/12/2004
Time: 6:36:37 PM
User: N/A
Computer: ComputerName
Description:
An error occurred in the function DeleteUnsafeAttachments while running the Secure Attachments Tool (Secatts.dll) to remove SMTP e-mail attachments. The error code is: -2146644475. To fix the problem, run the Configure E-mail and Internet Connection Wizard, and clear the option to remove e-mail attachments; then run the wizard again and select the option.

CAUSEThis behavior is caused by e-mail messages that contain MIME fields whose content type is multipart/alternative. The expected content type is multipart/mixed. Typically, e-mail messages that contain multipart/alternative content type MIME fields are the result of e-mail worms.
Less frequently, this behavior can be caused by a non-Microsoft antivirus program that is running a file-level scan of the Exchange folders. The file-level scan may remove infected attachments before Small Business Server 2003 can remove the attachment.
RESOLUTIONYou can ignore these events, and you do not have to run the Configure E-mail and Internet Connection Wizard. However, if you have an antivirus program that runs a file-level scan, Microsoft recommends that you configure the file-level scan to exclude the Exchange Server folders.
