Spell check for Russian language in Windows Mail

I've got Vista Enterprise 64 bit and Office 2007 Enterprise installed both in Russian version. But, although I can check Russian spelling in my Office programs, I can't do so in Windows Mail. There are only few languages for proofing, including English, French and some else, and I don't understand if I can somehow install additional languages - there is no such option displayed. Please help, because I need this hardly.

P.S. Don't suggest me to use Outlook.

I don't think it supports a Russian spell checker. You might need a 3rd party product. In General. For information regarding enabling multi language support in IMN, read Knowledge Base Article Q154654.

You will have to install some external software for spell check of russian language. There are lot such available on internet but most of which are paid.

This sound really disappointing that Russian language support is not there in Vista :(. Because in Windows XP (Russian version) everything was OK with Russian spellcheck.
