mail enabled document libraries not receiving email (sometimes) RRS feed

  • Question


    I am trying to setup a MOSS 2007 document library to accept e-mail. I have set it up using Steve Smith’s article “How to configure Incoming Email Enabled Libraries in MOSS 2007 RTM using Exchange 2003/2007 in an Active Directory Domain” from  I have it all working except for one item.  We have our Outlook configured to send messages in rich-text format.  If I send a message in that format it does not end up in the document library and there are no event log messages.  I have read Pat Cherny’s  article Inside SharePoint - Troubleshoot Messaging Integration at and followed his instructions to resolve this issue.  When I look at the e-mail message in the drop folder using notepad I do not see the “winmail.dat” that he describes.  However, all my messages that fail have “Content-Type: application/octet-stream”, whereas the messages that I send as HTML show up with “Content-Type: multipart/mixed”.   Our Exchange environment is mixed with Exchange 2003 and 2007, with the mailboxes still on EXCH 2003.


    Is there a way to make the Exchange-RTF to become mulipart/mixed instead of application/octet-stream?  I assume that is causing the problem.


    Is there a fix that I have been unable to locate?


    Since data can be coming from anyone, I have no control over their settings and may receive messages that are configured similar to our current environment.


    The following is a sample from one of the messages that does not get through.
