Does the word “return” sound too exaggerated in the sentence? One of my colleagues said that it does. He mentioned something about “Returns” being used as a title of one of those Batman movie, as in “Batman returns.” So it’s too much for a sentence like this.
I’ll let you know when he returns.

It is of moderately high register, but not too high for everyday speech.

No. I wouldn't describe it as "exaggerated".
It's just a higher register expression than 'comes back' or 'gets back'.
Suppose you are dissatisfied with some interaction you experienced with a clerk in a clothing store, and you ask to see the manager to register your complaint. You are told that the manager is at lunch at the moment, but that you are welcome to wait.
If you are in a store that sells very expensive and luxurious items, the attendant might add "I'll let you know when he returns" or maybe even "I'll inform you when he returns".
But if you are in a discount store that sells very ordinary items, the attendant might add "I'll let you know when he [gets/comes] back".

I should add that the "return" in Batman Returns is part of the traditional language of movie titles. It frequently appears in titles of sequels. If you search IMDB titles for "return", you'll see what I mean. This has helped keep it in the public mind, as has Douglas MacArthur's famous "I shall return."
