I know that Offline Address Book has a refresh cycle (24 hours by default) and you can change it with Set-OABvirtualDirectory and Set-OfflineAddressbook commands. but I was wondering whether such cycle exists for the Global Address List (GAL) as well and it there is, the mechanism to change the interval.
some places say GAL is simply against the live Active Directory, some places say that it is indeed something that gets refreshed periodically, so I really wonder what GAL is and how I can have control over its update.
