I cannot get the attach to email function in Acrobat X to work. In Acrobat 7.0, when in an open document, I could click the attach to email button and Acrobat would automatically open a new Outlook message and attach the document. When I attempt to perform this operation in X, I get an error message stating that Outlook is not my default email client, which I'm certain it is as this operation works flawlessly with Word, Excel, PPT, etc.
This is an issue all over message boards, with many programs other than (and including) Acrobat. If you install Microsoft Office as 64-bit, many applications cannot address Outlook to launch it as your default email client, even if you select it as the default in Start Menu > Default Programs > Set your default programs.Microsoft recommends you install Office as 32-bit, unless you are doing SERIOUSLY complex Excel work.

"One of the applications that Microsoft does not support with "Save As PDF is Outlook".
