Gal not updating automatically
Note: if you get an error stating that Enable-Organization Customization commandlet has not been run, execute it (without any parameters) and give it half an hour before reconnecting to Exchange Online and trying ABP routing operation again.Group membership-based address lists and global address lists rely on Member Of attribute filtering.This step could be done on one of your ADFS farm servers that has Windows Azure Active Directory Power Shell (WAAD Posh) installed.Launch WAAD as Administrator (elevate if you have UAC enabled).cmdlet is run then a ‘synchronize now‘ event is marked and the update is not actually run immediately.The event itself happens the next time abserver looks to see if a sync event has been triggered.
The second half of the server-side process is controlled by the Address Book Service which pulls information from the SQL database and writes the changes to the address book files.
Administrators can create multiple address books and global address lists and filter them to only the specific contacts/mailboxes/groups.
This makes it possible to lock down any given user to viewing contact details only of the employees they are supposed to see, creating an impression that the user is in a different Exchange / Office 365 organization. It was possible to do this in on-prem Exchange 2010, Exchange 2007, and even as far back as Exchange 2003.
