A user has a win 7 Pro (64bit) with Office 2010 installed. She e-mails a PDF file to employees using outlook. The employee's that use outlook get the PDF with the .pdf extension. On OWA the attachment is there but the extension is missing. I can forward this e-mail in outlook or OWA to myself or others and the .pdf extension now appears. This is only happening to one user. If she uses OWA to send a pdf file, the .pdf extension stays. Her settings on outlook is set to use HTML when composing an e-mail and when using in Rich Text convert to HTML. Does anyone have any ideas on how to fix this issue?

Ed, I don't want to show the file extensions for all files on the computer. When user "A" e-mails a pdf to someone within the district say user "B",and user "B" opens the e-mail using OWA, they see the file attachment but without the .pdf extension. Example: "BoardAgenda". All other documents show their files extensions. Examples: "BoardAgenda.doc, FinancialReport.xls". User "B" can download the file but it will download without the .pdf file extension. User "B" can add the file extension and then view the pdf file. I hope this helps.

James, I'm not sure what ru stands for but I got the following info. Win 7 Pro SP1, Office Pro Plus 2010 Version 14.0.6112.5000 (32 Bit), Outlook has SP1 installed. I did not see a SP2 for Office or Windows. I hope this helps.

I should have mention this sooner. We have a front end and back end running on Exchange 2003 (Version: 6.5.7638.1). I was not able to find how to configure Public and Private Computer File Access. I did look at "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWEB\OWA" Level1 and 2 Filetypes and MIMETypes. I found no mention of PDF. I added "application/pdf" to KnownContentTypes reg key to see if it helped. The issue still continues.

Hello, Since the issue only occur when sending the PDF attachment via Outlook, you may also ask the question on the Outlook forum: http://social.technet.microsoft.com/Forums/en/outlook/threads Thanks, Simon

Why not? I hate Mac mode and it's my opinion that hiding extensions reduces security, making it possible to send attachments like FunGame.txt.exe and hiding the true intent.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

It turned out that a tech installed Adobe Reader X Pro without uninstalling Adobe Reader X (Free Version). I uninstalled the free version and sent out a few test e-mails. The PDF's now keep their .pdf extensions in OWA.
