There are quite a few possibilities here. Let's list them and give a quick mention of possible issues.

Attach the file to an email message. Often the easiest answer, but the receiver might not know how to deal with an attached file. You need to verify they have the correct application on their machine to open the attached file. You need to verify they use an email program that can deal with an attached file. If the file is large (2+MB) an attachment will often be rejected by the receiving system. Note that attached files are often larger than the original when sent due to the methods of encoding the file.

Place the file somewhere the user can connect to download it. This is usually quite tricky as it involves FTP, FTP servers, explaining how to use FTP, etc. Also, you do not want a user giving out their username and password so that someone can get to their account to get a file. This is a very bad idea, and against University policy.

Place the file on a Website and allow the receiver to download it via a Web browser. Not a bad idea as long as the file does not need to be secure. If it does need to be secure then you may need to deal with methods for password protecting the file.

If text will work, use this and send it in the body of an email message.

Fax the printed document if appropriate, and/or send the file via mail on a disk!
