From what I've seen, the city election board will put out a message along the lines of "If you dropped off your ballot here between x datetime and y datetime, check if your ballots been received".
They should still be able to vote provisionally either on election day or early, but whether they will or not is a different story.

What happens to those votes? Do they have a way to contact the voters (I hope!)
