I just spent the last 5 hrs of the day looking for a way, within Windows/Exchange, to enable a couple of users in my organization to update the GAL. As many of you know, it's very inefficient when users have to go through the administrators to make GAL information changes.
I'm very aware of the various 3rd party tools available that would enable select users to update GAL information for the entire organization. I even attempted to use the GALMOD32 utility, but no luck. I made sure to adjust the appropriate permissions and delegate control at the OU level as advised by Microsoft KB 272198. I was able to get it working to where the domain user is able to modify his/her own GAL information, but not everyone else's. I'm very surprised that Microsoft doesn't have a utility that allows this type of administration. I was expecting to come across a type of updated GALMOD32 utility to address this concern in Exchange 2k3. Perhaps, I didn't look hard enough and didn't find this utility. I'm a little hesitant about purchasing a 3rd party application for this task not because of the money, but because of compatibility and potential issues caused by the application and Exchange. Anyway, I would appreciate if someone out there has come across a better GALMOD32 utility...
