Password protected files do not preview.

Can someone help me?

When I upload a password protected file with restrictions on printing and editing it does not preview the file. I have not set any password for viewing or opening the file. I want to share the document but not allow for people to download it i.e. just for online viewing.

I do understand that download of the document is inevitable for a person that has some basic level of computer literacy but still want to get that done.

Is what I am trying to accomplish possible?

Regards.

Edit: I am referring to Acrobat.com document management and sharing.
