No longer able to password protect a pdf added as attachment to Outlook message

[keving5714911]

Up until a few weeks ago, I could add a pdf to an Outlook message, open the pdf, add a password to open, close the pdf and send the email.

Now when I attempt to password protect the pdf within a message, the pdf opens the save as box and requires that I save the password protected pdf someplace before the password is added.

Help?
