Are you using a hosted BES solution? They provide wireless sync of PIM data, so the version of Office should not matter.
Having said that, I have not tested BES with Office 2007.
I use Office 2007 on a Hosted BES (L2E). Not a single issue.
Office 2007 is probably my least favorite version to date. Complete memory hog, and I've got a 3ghz processor and 2.12gb RAM. Still stalls on me.
