I got an email supposedly from dropbox. with the subject "ATTN: We recommend completing your Dropbox setup ASAP", and then saying "Your files are nearly ready to be uploaded", followed by a dropbox.com link, with the following format https://www.dropbox.com/l/XXXX0x_xxxxxxxxxxxxxx_xxxxxxxxxxxxx/h (characters are different). This seems like it could be legit, but also could be some kind of scam ? Any way I can confirm what it is without clicking the link? I tried searching for it on google and got no results back.
