AD service managers are responsible for the GAL data, though Exchange service managers have access as well.Microsoft Outlook clients use a cached mode of the GAL, called an Offline Address Book that is synced with the GAL at a nearly daily interval.This screen shot shows how you can scroll through various pictures and view the location of where those pictures originated: Another nice feature of the OSC connector is that you can view all of your Linked IN contacts directly from the Outlook Contacts navigation bar: The client side method is the default behavior, as users are left to themselves to upload and keep photos updated.This is done by simply opening a contact and clicking on the photo icon, then browsing for a photo to upload.
Information in the GAL is only updated once a day from AD.
Most home and personal accounts do not use Microsoft Exchange. The Offline Address Book contains the properties of a user, such as e-mail addresses, that Microsoft Outlook requires in order to send an e-mail message and display information about the user.
By using the Offline Address Book, Outlook does not have to connect to Exchange in order to resolve names or open the records for each user.
If you enter that URL in a browser, you should be prompted for your Exchange credentials.
This feature requires you to use a Microsoft Exchange Server 2000, Exchange Server 2003, or Exchange Server 2007 account.
