Recently, I had to write an email to one of my professors regarding an urgent matter. I was basically asking him for some guidance in the matter.
I am not a native speaker and normally I end my formal emails with 'Best regards'. Since this was important to me and I wanted a quick response I wanted to sign with 'Your hopefully'. I didn't know if this would be an appropriate way of ending a letter to a professor.
Is 'Yours hopefully' formal or informal? Is it still used to end letters with?
Note: I have read the following posts.
Is it "Yours faithfully" or "Yours sincerely"?
Is usage of “Yours sincerely” still appropriate?

As far as I'm aware, "yours sincerely" and "yours faithfully" are the two formal closings with their own rules described in the article you link. I haven't come across "yours hopefully" before and whilst it can make sense, as @Lawrence says, then it could be fine to use. However, if you'd like to stick to more standard endings, I would suggest a closing sentence such as "I hope to hear from you soon" / "I hope for a resolution to this matter", followed by the more standard closings.
Another option which I recall seeing could be "Yours in anticipation".
Finally, depending on your location, there are US/UK differences to bear in mind.
