SharePoint 2010 - PDF Security

IE8 and PDF files in SharePoint don't necessarily play nice together for a reason - security. By default you'll click on your PDF and get an option to either Save or Close. Here's a good explanation and the reason you should use an ‘Inline Download’ exclusion as opposed to the common (but not recommended) Browser File Handling setting in Central Admin.

PowerShell Script:

$webApp = Get-SPWebApplication http://webapp.domain
 If ($webApp.AllowedInlineDownloadedMimeTypes -notcontains "application/pdf")
   Write-Host -ForegroundColor White "Adding Pdf MIME Type..."
   Write-Host -ForegroundColor White "Added and saved."
 } Else {
   Write-Host -ForegroundColor White "Pdf MIME type is already added."

In addition, if you want your PDFs to open in a new window or even in Adobe Reader you'll want to change your local Adobe Reader client settings:

Open Adobe Reader
Select “Edit” –> “Preferences” from the menu system.
Select the option on the left called “Internet”
Either select or de-select the option called “Display PDF in Browser” depending on your preference.

SharePoint Administrators, don't forget your PDF iFilter for searching those PDFs!
