We have Exchange 2003 Management Tools installed on Windows XP Pro PCs that need CRM 4 installed on them. CRM 4 cannot be installed on machines withExchange 2003 installed. I can remove the Management tools, but the base Exchange install remains. I can even getExchange to disappear from Add/Remove Programs, but when I come to install CRM 4 client on my PCit says that Exchange is installed still and will not continue the installation. How can I completely remove Exchange 2003from my XP Pro PC?

Hi Dave, Try below things and see if it is resolved. Remove the directory where Exchange installed. Remove the below registry key if it is still exists. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeSA
