This helps make sure that Outlook 2007 (and higher) clients using Web access for OAB updates point to the right location.
This is located in the Exchange Management Console - Similarly, if your organization uses public folders, make sure that mailbox servers at each site are listed in the replication tab within public folder properties.
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.
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.
You should also make sure that the OAB references on each site's Exchange server are correct.If you make a change to your organization and want to ensure that replication occurs immediately, you can force synchronization using the following Exchange Management Shell command: About the author Dave Leaver has worked in the IT industry for the last ten years as an IT support engineer.They should be inherited by any child folders of the OAB public folder by default, but it's not always the case. Remember, the slower your links are between the sites, the slower replication will be between servers.Thus, Exchange Global Address list updates will process slower as well.
You should also check that all four sites can communicate on port 25, in order to allow replication traffic to pass through.The easiest way to test this is to use an old Microsoft tool known as
