I have a specific sender send the PDF being remove and replace by filename.pdf.txt
Similiar to http://social.technet.microsoft.com/Forums/exchange/en-US/8c35b394-915a-475f-af88-de0a465fb5c8/this-attachment-was-removed
We had added "add key="AllowInvalidAttachmen
I did my GMAIL and send a test with "my PDF", and the user able to receive it.

Simon,
The sender is external user. Mail from external will be reach Symantec Message | Edge server | Hub Server and Mailbox.
On Edge and Hub server, i have ForeFront Security for exchange installed. I did look at the quarantined on Forefront and found nothing.
Following is what I did so far:
1. External user send the PDF email to my GMAIL, PDF able to open
2. External user send to my company account, PDF being removed and replace with filename.pdf.txt
3. Compose a new email in GMAIL, and attached PDF from no. 1, send to my company account, PDF able to open.
4. Sent a different PDF from my GMAIL account to my company account, PDF able to open
5. "AllowInvalidAttachment" set to a couple month back on Edge and Hub
6. If external user zip the PDF file and send to my company account, the zip file able to receive and PDF can be open.
I have no idea where to check next

I operate a simple policy - where there is a Symantec product involved, that is the cause of the problem, it doesn't matter what it is. Therefore you need to start there.
If you look at the text file, does it say anything?

The text file said "This attachment was removed"
We used Symantec MessageLab Cloud. From tracking i did on Message Lab, it show there is a PDF attachment available
It happened ONLY to this sender

It has to be the format of the PDF file. Not all PDF files are equal. iI might be seen as invalid and therefore blocked.
You could ask the sender how the PDF file was created.

The sender will manually send the medical claim in PDF format. They manually send it but generated by the user.
They did sent me the same PDF file to my GMAIL, I able to receive and open it.
When i use the same PDF which received in my GMAIL and compose new email and send to my company account it work.
I did ask the sender to send another PDF file, same issue occured. it look like only sender from this domain having the issue.
Not sure to where to check further.

That doesn't really answer the question.
Sending the file to your Gmail account doesn't prove anything.
If they sent you another PDF file that was created by the same PDF tool, then it may still be rejected by Exchange. They need to try a PDF from another source, such as a public web site or from Adobe themselves to see if the file comes through.
If a public PDF file is rejected, then it has to be something they are doing to the files that is causing them to be seen by Exchange as invalid.

I had asked them to send a PDF from another source. They sent us 2 copies. 1 PDF create after converting a simple word file to PDF and another 1 is download from website.
I will ask them to download a PDF file from Adobe and send it to us.

Simon,
Thank you for your reply, yesterday I'm asking sender ( his colleagues, same domain email address) to send same PDF to my company email account. I'm able to open the PDF just fine.

Just to update.
Today, I call the sender and asked her how she did sent the PDF. Basically, she use Outlook Online to send the PDF file
When her colleagues sent me the PDF, she use Outlook client on her PC. The PDF able to open.

thank you for your suggestion
Exchange doesn't do this - I would suspect third party utilities.
