Fixed using the following:
Exchange Server 2010
1. Stop the Exchange Transport service.
2. Locate the EdgeTransport.exe.config file. This file is located in the following path:
<drive> :\Program Files\Microsoft\Exchange Server\Bin\
3. In the EdgeTransport.exe.config file, add the following entry between the <appSettings> element and the </appSettings> element:
<add key="TreatInlineDispositionAsAttachment" value="true" />
4. Restart the Transport service.
We have a problem when receiving emails from a particular sender. The problem is that the attachments don't show up in Outlook 2010 or OWA, but if you view original message in OWA you can see the attachment.
I managed to intercept the mail using our Barracuda Firewall and Antispam and save the message as an EML file. I have noticed the problem lies with:
Content-Disposition; inline; filename=Oak.jpg
If I change this to
Content-Disposition; attachment; filename=Oak.jpg
and resend the message I can see the attachment. I SP2 and Update Rollup 4-v2 for Ex 2010 SP2 installed.
