Recently a client migrated their SBS 2003 to a new SBS 2007. They are still using Office 2003 and are having some issues receiving some attachments. This issue persists on Multiple users but does not appear to be happening on all incoming emails. I found a KB stating this was a known issue and to verify that Exchange was fully patched. I found that it was not so we installed SP3 for Exchange to see if that would help. Unfortunately it did not help, we are still having the same issue. If I take the email and forward it to a gmail account the attachment appears and the user can see the attachment in OWA. If I then take the email and forward it from the gmail back to their exchange email it also works. Which originally lead me to believe that it is on the senders side, unfortunately if I have the sender send directly to the gmail account or my exchange server (2003) the attachment is there in both accounts. I did find KB - http://support.microsoft.com/kb/961940/en-us but wanted to know if there is anything else I am missing, I would rather bring a solution to the client rather than a workaround!

Hi Are the users experiencing the same issue with both Outlook and OWA? And it's not filtered in any sort of mail washing? IMF? 3rd part? Jonas Andersson | Microsoft Community Contributor Award 2011 | MCITP: EMA 2007/2010 | Blog: http://www.testlabs.se/blog | Follow me on twitter: jonand82

Hi, I found another solution, you could have a try. 1. Run this command: Set-OrganizationConfig –ShowInlineAttachment: $true Run this command to verify the result: Get-OrganizationConfig 2. Add a new entry in the Edgetransport.exe.config XML file on Edge server or Hub Server The detailed processes could be found in the following KB. http://support.microsoft.com/default.aspx?scid=kb;EN-US;954684 And I found some other workaround except view the attachment in OWA 1. In Outlook 2003, save the attachment locally, and then view the attachment. 2 .Use Microsoft Office Outlook 2007 to view the attachment. More information about the workaround : http://support.microsoft.com/kb/930468 TechNet

Jonas, This is only in Outlook and it is actually Outlook 2007 not 2003. OWA works and if the user forwards to a POP account such as Gmail it works. The mail is not being stripped of the attachements so I do not believe this to be a barracuda or spam issue. As I can take the message and either view it in OWA or forward it to a different account. If I forward it to say Gmail and then send it back all of the attachments are visable. So it leads me to believe that it is a sender issue. So I tried sending the user the same set of attachments from my exchange account and she was able to see 2 of the 5 attachments (3 of them which were pictures were hidden). Basically what I get out of this is that this is partically a sender issue as well as a receiver issue. From what I read the MIME header gets messed up and Exchange 2007 reads the files as inline so it hides them as attachments. I tried an option I found that made a rule in the hub transport to change the header to "Multipart/mixed" but that failed to resolve the issue also. Jerome, I too found these solutions they state they are for Exchange 2007 SP1 and SP2. I upgraded to SP3 when this issue first started. The "Set-Orgainization - ShowInlineAttachment$true" is a command I was going to try to run today though it states it is for SP2 and that the "Edgetransport" was for SP1. If that ends up working I will let you guys know.

Ok, waiting for your good news. According to search for this issue in Microsoft KBs, most point out MIME header is a part of a message which was defined in RFC. So I think, if this solution don’t work, you could only educate user a workaround.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

No good news unfortunately. I did confirm that if I force my email to "HTML" instead of "Rich Text" so that the attachments do no go inline that they view with no issue on her end. So this is 100% an inline attachment issue. At this point I am at a loss, it appears this is a large issue with Exchange 2007 why it reacts differently from different emails is beyond me, if I send from my personal account (Gmail) there are no issues at all. I am going to try to install Outlook 2010 on a PC onsite and see if that works. They do not want to upgrade currently for financial reasons (Just put in a SBS 2008 server) so this will just be for testing, at least we will know what will resolve it in the future if Outlook 2010 works. I will keep you guys updated, it appears this will happen sometime next week.
