Global address book not updating new users

New users don’t show up in the GAL for clients using Outlook 2003 Cached Mode clients, because Outlook uses an Offline Address List (aka “Offline Address Book” or OAB), which is generated once every 24 hours by default [read previous post “New user does not show up in GAL“] In this case there are who did show up in the GAL earlier but have disappeared now.With Diagnostics Logging for .– Default Offline Address List On closer inspection:– The reason these recipients show up in the “All Users” Address List is because that Address List is not part of the OAB – only the Default GAL is, as shown in the screenshot below.

We had a problem where any new user mailboxes that were added to the Exchange server were not appearing in the address books of Outlook 2007 clients running in cached mode.The address book was up to date in OWA, but our cached Outlook clients wouldn’t update even after forcing a download of the OAB.If I took the Outlook 2007 client out of cached mode, they would see the latest address book.The way we fixed this was by going into Exchange Management Console (EMC) , Organization Configuration , Mailboxand then clicking on the Offline Address Book tab.Double click on the Default Offline Address Book then click on the Distribution tab and untick “enable web based distribution” .

OK out of this menu, then go back in and retick the “enable web based distribution” , add the servers that you want to use for web distirbution and OK back out again.

You should now have an updated OAB when you download it again.

Frequently users report recipients missing from the GAL. Scenario:– Recipients are not hidden from Exchange Address Lists– Recipients do show up in the “All Users” Address List– Recipients do show up when Outlook’s not in Cached Mode– Recipients resolve in Outlook Web Access Some recipients may not be included in the Offline Address Book when it is generated, for a number of reasons.

Default Address Lists (See Screenshot right) Once you realize that there are a handful of built-in Address Lists, you soon realize that you could create your own Custom Address Lists.

However, be careful, don't create too many lists, and furthermore, give thought to meaningful names for your lists.

The situation, you want to modify the GAL, however, you discover that you cannot edit (or delete) the Default Global Address List.
