HiGuys, I would like to know how long doesGAL update once there of new mailbox created?eg. couple of new mailboxes created attime 10AM (local server time),how long does ittake to getGAL update normally? soit will appear onoutlook client's address list..I even did try toupdate the offline address bookdatabase manually.. but it didntget GAL update on outlook clienttoo..also, can the update timing be customize? Please advise... Appreciates any feedback and many thanks..p/s we used cached mode for outlook client and OAB event log level set as high, there is no warning report for OAB generating.

In Exchange 2003 it depends on RUS and OAB update schedule (By default, Exchange generates the Offline Address Book once a day at 4:00 AM)and then when your Outlook try to download OAB.All these steps can be done manually.

Hi,If you are in Exchange 2003 then open ESM and -> recipients -> OAB -> Properties -> you will see the updte interval. Thereyou will find the details on what Interval GAL is updated.You can modify the sameIf you wanted to forder to update GAL then you may right click on the OAB and select rebuiltIf you are Exchange 2007 Get-OfflineAddressBook |fl Will get you the details of the Offline Address book and below command will force to update AddressbookGet-OfflineAddressBook | Update-OfflineAddressBookThen you may try to download OAB from the outlook to check if it works outRegards,Krishna|MCSE:M|MCTS:Mhttp://smtpport25.wordpress.com

my bad, i thought this was the purely exchange 2007 forum.. sorry bout that.. i am using exchange 2007, so guess what Krishna you said, I have done that already.. manually rebuilt OAB by using GUI and exchange CMDLet but it still hasnt update to OAB. There is no obvious error reported in event log.

How about updating Outlook by following below steps...?- On the client go to Outlook 2003/2007 | Tools | Send/Receive | Download Address Book.- Uncheck Download changes since last Send/Receive- Make sure Download Full Details is checked- Click OK, wait for the download to complete (depending on your bandwidth and size of OAL, this may be close to instant, or it may take a few minutes)- Check if the user appears in the GALIs it showing correctly in OWA?Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com
