Simple it doesn’t work, because IIS in Exchange 2007 requires 64 bit mode,OCS do the opposite this is because OCS CWA dlls requires to run in IIS x86 mode,, if you installed OCS with Exchange 2007 (for your labs or worst for your production environment) the exchange will collapse, here is how to fix it:
- Uninstall OCS 2007.
- Run the following script CSCRIPT %SYSTEMDRIVE%\Inetpub\AdminScripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0
- Restart IIS
