When we recieve email messages with ZIP attachements the files are striped from the messages, before they can reach the Forefront Scanner. So it seems when we recieve zipfiles with passwords that arent created by winzip the Transport agent strips the Attachement. The question for me is now, why didnt the setup of forefront disable the transportagent "Attachment Filtering agent" option. Do you know some workaround!? I realy don't want to disable all Attachment Filtering Agent Thanks a lot.

Tested with another 2 users in our office and they CAN send attachments to the same organisation. Affected user is able to email attachments to all other organisations as far as we know and we have also tested with gmail accounts, etc, and all come through ok.
Turns out that the issue was ours. Our Signature Software Exclaimer which adds sigs to outgoing mail had somehow started stripping attachments.How rite and ritual is born from our self-centred viewpoint.
Check the Exchange mail flow and track the message, if you see it leave your org with the attachment, then it's out of your hands and is getting stripped someplace else. We are on Exchange so would this be Message Tracking Centre? I can find the message and can see the point it was relayed to the external recipient, but how can I tell whether the attachment was present when it left our organisation?
Again something else that is pointing me towards the recipient and not the sender. Agreed, especially if you can see it leaving the org. As for seeing the attachment leave, not sure on that one and don't have a to test. You would need to open the message in the message tracking center but my guess is if you see it being archived with it in GFI then it's there because Exchange see's the GFI just the same as sending any email, so if your Exchange had a problem with it, it would strip it from that before sending it as well.

This creates a compressed archive file that has a different file name extension. Outlook does not recognize these file name extensions as potential threats. Therefore, it does not block the new attachment. When the sender resends the new attachment to you, you can save it on your computer, and then you can use the third-party file compression software to extract the attachment.
If you need help using the third-party file compression software, see your product documentation. If third-party file compression software is not available to you, you might want to request that the sender rename the attachment to use a file name extension that Outlook does not recognize as a threat. For example, an executable file that has the file name extension.
Ask the sender to resend the renamed attachment to you. After you receive the renamed attachment, you can save it to your computer and rename the file again to use the original file name extension. Follow these steps to save the attachment and rename it to use the original file name extension:.

If sender is internal the specific. Also it only applies to. It is not stripped if I send it from internal user because no edge interaction.

The attachment is still stripped. To be honest for me this issue is narrow as it is. Attachment gets removed by Attachment Filtering on our Edge server.
