Well, many IT departments block access to Dropbox (and other cloud storage solutions) to limit the bandwidth expended by employees. If it isn't explicitly against the rules, though, I've found a solution that lets you get a file to Dropbox without relying on any of those options. You can just e-mail it.
Habilis is a free service that syncs with Dropbox via e-mail. Just visit the site and, if you're signed into Dropbox, you can click the link to associate Habilis with your Dropbox account. It only takes a moment, and then you'll get a unique e-mail address. Save this, because now you can upload files to Dropbox just by sending attachments to this address.
The service works like a charm -- it's fast (files appear within minutes of sending the e-mail) and it's free of advertisements or other annoyances.
