When I look up that word it means to fulfill. However I've seen a sentence where it looks like you can fulfill a person. Here is a version of the sentence:
Une étude des Écritures prouve que Paul a été exaucé. (the context being that Paul had been praying)
I haven't been able to find another occurance of the verb being used like this but I've been told by native speakers that it's definitely correct but I've not yet been able to find an explanation online as to why.
