Outlook 2010 cannot open certain PDF attachment.
I have one user whose Outlook 2010 opens his own mailbox and another mailbox to receive purchase order. For some reason, he was not able to open PDF file from a sender's email which has an attachment in PDF format. Other users who open the same purchase order mailbox in their Outlook are okay to open that PDF attachment directly in Outlook 2010. If I send another PDF file to this user and he opens in his own mailbox, it is okay.
He uses Outlook 2010 on Windows 7 Pro 64-bit OS.
Anyone experienced this issue before and knew how to fix it?
Thanks!

The user can not see that attachment in Outlook on another mailbox, he opens two mailboxes, one is his own and anther one is a mailbox which is accessed by a group of people, all of them have the full permission given in Exchange server. When he clicked on that email with PDF attachment, Outlook displayed a message saying - "Outlook blocked access to the following potentially unsafe attachments:..." He could not see that attachment at all.
you would require making some registry changes, please see the link below for detailed procedure.

I have already tried this registry change, still Outlook displayed to block access to the attachment, in fact, after adding that String Value, that user cannot open any PDF file directly in Outlook, even in his own mailbox when he received an email with PDF attached. He got a warning message to ask him to save the attachment. He wanted to open PDF directly in Outlook and he was able to do that before.
Thanks.

We have been using Outlook 2010 (32-bit)for the past 5 years, never need to use such tools for opening attachment. I would like to find out why all the sudden this issue came up. It only happened on two users so far, other people are okay, it must be something get updated/changed on their Office 2010 applications. I have checked their computers and as the system admin, I know there are no other software/updates installed recently except MS updates.
Thanks.

Open Regedit and navigate to
Computer\HKEY_CURRENT_USER
Create a new MZ String Key with the name of Level1Remove
edit the values i.e. unblock js
.js
To unblock JavaScript, VBScript, and exe files, enter:
.js;.vbs;.exe
Save and exit regedit, reopen outlook you should be able to open PDF's now.

Hi David,
I have tried this method, it won't fix and Outlook still blocks PDF attachment, as I replied to Sunil's suggestion earlier. I also searched Microsoft article and asked user to forward that email to himself, still no luck.

I correct, the problem is due to the presence of two points in the filename. If the name of the file is of the "Name..pdf" type by the problem, if the same file is renamed to "Name.pdf", the problem does not occur.

I have tested and verified, When KB3203467 is installed, any email attachment with two or more points in the file name will be blocked by Outlook 2010. Once KB3203467 is uninstalled, such attachment can be accessed and opened directly in Outlook 2010. If there is no . in the attachment file name, Outlook can still open the attachment even computer is applied with KB3203467.
Thanks.
Thanks.

Fixed! Uninstall MS KB3203467 can resolve this issue which is caused by MS Updates.
