Exchange 2003 does not support IM 5.1 If you want to continue to use this feature you must keep an exchange 2000 server in your environment. No way around it. But it will work that way, we are still using IM 5.1. Keep in mind it is an end of life product no longer supported by Microsoft. You may instead want to look at Live Communication Server, but it is not a free product like IM 5.1
