hi Can i Install OCS 2007 on Exchange server? Any Reply will be appreciated REGARDS Sohaib Qazi

It has always been MS recommendation to keep Exchange separate from any and all other applications. I recommend doing so, as well. When needing to troubleshoot your OCS, this could bring down Exchange as well. If they were segregated, this wouldn't happen. Exchange also just doesn't tend to 'play nice' with other apps.
