Manually Update Global Address List (GAL) on Exchange 2010

Manually Update Global Address List (GAL) on Exchange 2010

Our infrastructure automatically updates “offline address book” and distributes changes to clients once that is submitted by Generation server.
Microsoft System Attendant service is answerable for the Generation of Offline Address Book, and server hold mailbox role can only have this Service.

You can also check the Generation Server below follow path:
Exchange Management Console -> Organization Configuration -> Mailbox -> Offline Address Book Tab.



Everyday Offline Address Book is distributed to clients every 24 hours, if you click on properties of Default offline Address List you will get the below window, this is where you can customize your update schedule.
 

Two important thing to ponder upon is:

1. Enable Web-Based distribution:
Used to distrubute OAB running outlook clients 2007/2010.
2. Enable public folder distribution:
 Used to distrubute OAB running outlook clients older than Outlook 2007.
If there is any change that has occurred on your infrastructure during working hours than you can try to force the generation server to create the OAB and distribute the OAB through Web-based distribution:
Path:
Exchange Management Console -> Organization Configuration -> Mailbox -> Offline Address Book Tab.
Right click on your address book and select update.

 

You will receive the following message, Click Yes


Above Steps can be done using PowerShell:
Update-OfflineAddressBook –Identity “Default Offline Address Book”

After go to client access server and restart Microsoft Exchange file distribution service from services

Above Steps can be done using PowerShell:
Update-FileDistributionService OABGenerationServer -Type OAB

Goto Offline Address Book location and check the date and time changes:
Path: C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\OAB



Q. How Microsoft Outlook 2003 receives Offline address book? What is the OAB generation process?
Microsoft Outlook 2003 and older version receive Offline AddressBook from the System Public folders located in Exchange, Offline AddressBook Generation Server unwraps the public folder and renews the changes.

Q. How Microsoft Outlook 2007 or outlook 2010 receive Offline address book? What is the OAB generation process in exchange 2010?
Microsoft Outlook 2007 and 2010 make user of AutoDiscover to search the Offline AddressBook update link(url) and it connects to concerned server that has the OAB files for distribution and i.e., Client Access Server is answerable for any request to download OAB by outlook clients.

CAS specifically has the MS Exchange File Distribution Service which pulls the OAB ExchangeOAB files(folders) from Mailbox Server(OAB Generation Server) in Client Access Server so that it can be distributed through web-based distribution point:

Web-based Distribution Point Path: C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\OAB (Inside this will be a GUID folder which holds the OAB files)

As our OAB is now ready to be downloaded, Outlook clients can download the OAB from Web-based Distribution point. In Outlook 2013 Click in SEND/RECEIVE tan -> Click on Send/Receive Groups > and Click on Download Address Book.

 Offline AddressBook Location in Client Machine:
2010 and 2013:
C:\Users\ (username)\AppData\Local\Microsft\Outlook\Offline Address Books\ (GUID)
