Clarification on 彼のほかに私たち皆が行った


I am studying sentences with my colleagues and this was one of the sentences
we picked for the week:

[code]

    All of us went besides him.
    かれのほかにわたしたちみながいった。
    彼のほかに私たち皆が行った。
    
[/code]

After I consulted with a native speaker, I was told that the sentence makes it
sound like "everyone went", as in "he went and we all went as well". To have
the meaning I originally wanted I have been told to use this instead:

[code]

    かれいがいのわたしたちみながいった
    
[/code]

But then, my colleagues asked another native speaker which said that the
original sentence was OK.

I would kindly like to ask the community for some additional opinions.




`のほかに` means "besides" as in "in addition to"; `いがい` means "besides" as in
"excepting". So the sentences with `のほかに` means "In addition to him, we went,
too", while the one with `いがい` means "With the exception of him, we went".




`のほかに` means "besides" as in "in addition to"; `いがい` means "besides" as in
