Use of "too much" in passive voice verb structure

I encountered this passive voice sentence in a textbook: "He was influenced too much by Japanese fashion."

My understanding is that the words "too much" are functioning as an adverb in this sentence.

• "He was influenced by Japanese fashion too much."

• "He was influenced too much by Japanese fashion."

However, it seems strange to say, "He was too much influenced by Japanese fashion." I can’t understand why it sounds strange to me, however.

If I replace "too much" with a different adverb, it seems to work fine. For example:

• "He was quickly influenced by Japanese fashion."

• "He quickly was influenced by Japanese fashion."

• "He was influenced quickly by Japanese fashion."

• "He was influenced by Japanese fashion quickly."

To add, if I use "much too" the sentence seems correct. For example, "He was much too influenced by Japanese fashion" sounds correct to me. I understand "too much" modifies nouns, verbs, and adverbs, while "much too" modifies adjectives and adverbs based on this post: "much too [something]" vs "too much [something]"

However, I just can’t understand why, "He was too much influenced by Japanese fashion" sounds strange to me.

I think I made a mistake in my thinking. What do you think? Any help is greatly appreciated!
