I accidentely set a deny permission to the group Everyone for my Mailbox store. It is mounted, working, but I dont have access in System Manager or ADSI Edit to this store.I found a resolution for recovering permissions for a public store here: http://support.microsoft.com/?id=300444, but I cant find the right syntax to use DSACLS utility for my mailbox store, which is in the first storage group.Can you help with the right syntax?

Any luck with this...I've done the same thing
