Display email in userform textbox

[Lewis B]

Hello everyone. I'm wondering if it's possible to populate a userform textbox with the contents of a saved email. All of the searches I've done appear to address the opposite, which is to say, "put textbox values etc into an email/word/text/etc. I'm storing links to documents (xlsx/m, docx, txt, msg, etc) in an Access database, using vba/sql to populate the list box with those links and open the document (on click event of the listbox item). Rather than opening the document, I'm hoping to simply display the contents of the document in a textbox on the userform. Is this possible and if so, could someone nudge me in the right direction?
