R7 Teamroom on R5 Server (browser access)

We are using the R7 teamroom design on our R7 server, but have been asked to replicate to an older R5 domain where the clinets will use browser access.

Many functions work fine, but some do not and return “HTTP Web Server: Lotus Notes Exception - Invalid formula: unknown function/operator”

Can anyone confirm my conclusion that the R7 design will never work on an R5 server? Do you know which functions might be causing the trouble?

New features were definitely added between R5 and R7, and we do not support using the TeamRoom template on a prior-release server. Sorry, I do not know specifically which new @functions were used.
