No, OGA validation checks against activation dadabase if the key has been issued by MS and that only 1 machine is using it. They also black list some legitimate keys that have been shared. Easiest to block the OGA by editing hosts file for VLK office 2007 for now, or use the "cr4ck3d" OGA files. 2010 we will likley use 180 day KMS server activations.
