Normally you will be able to uninstall the Exch from control panel. How ever you have to make sure that there are no mail boxes and Pfs attached to the server. Also make sure that you delete the DBs manually . After the unistall , check ADSIEDIT and make sure that all the instances of exch is deleted.Raj

Maam, Try to follow this http://technet.microsoft.com/en-us/library/aa998193(EXCHG.80).aspx After you uninstall the SBS exchange completely, reboot the machine and then instll exchange 2007. Now there are no changes that you have to do on OWA virt. directory. How ever you have run some shell commands to activate certs, configure internal and exterrnal URLs for OAB, OOF etc.Raj
