When you attach a document to an outlook email, a copy of the document is created and stored somewhere. You can obviously link to any location in the body of outlook. A hyperlink to a local document will not be useful to a recipient on another machine (without access to the local drive).
But, is there a way to hyperlink to an attached file? I don't think that there is any native way to do this, but is there any possible solution?
If it matters, the email will only be read by outlook. (i.e. intra office).
