The request to sign in to Dropbox to receive a document looked real, I had to look it up by searching 'Dropbox scams' and there are plenty of them. Then I realized the request didn't have my name. Took a minute, because it was prior to my first cup of coffee.
If you have a Dropbox account, easiest would be to log into it directly and see if there is a new document there, not ever go through the email link and especially if its mail you weren't expecting.
I've been getting a lot of linkedin emails telling me that people are searching for me. No, they are not. Turns out there are linkedin scams. I just delete the emails without opening them.
