Last Week I had into the problem that Outlook 2010 didn’t show some attachments. After a research on technet I found out that this attachment was a not referenced inline-attachment.
To fix this behavior and make Outlook showing the attachment you have to do the following:
- Stop the Exchange Transport service.
- Locate the EdgeTransport.exe.config file. This file is located in the following path:
C:\Program Files\Microsoft\Exchange Server\Bin\
In the EdgeTransport.exe.config file, add the following entry between the
<appSettings> element and the </appSettings> element:
<add key="TreatInlineDispositionAsAttachment" value="true" />
- Start the Transport service
