Outlook cached mode global address list not updating
Exchange 2013 only supports Outlook 2007 (post SP3 and cumulative update), and Outlook 2010 must be at SP1 with cumulative update. For public folder distribution ensure the public folder database is mounted, and at least one server holds a replica.
Also in the properties of the mailbox database, your users are using, make sure it points to the correct public folder database.
So there are three factors stopping you seeing that new user on the GAL (, however if that’s not an option, read on). Force your Outlook Client to Download the Offline Address book. Check that the OAB is getting distributed from the Exchange/CAS server. Note: Make sure the Generation Server is set to a server that exists, and it’s online.
Support for Outlook 2000 was dropped with Exchange 2007, Exchange 2010 only supports Outlook 2003 (post SP2). In the diagram below you can see this server is performing public folder AND web based distribution, this is probably because you ticked this box when you installed the product.
In order to reflect any changes or updates made to the Global Address List, you can force Outlook to download a new copy of the GAL.
If you are not seeing correct contact information in the GAL for someone that has a valid email address (i.e.
someone who just received a CUMC email account, a new student, someone who recently changed their directory information) please use the steps below to synchronize your computer's locally cached version of the GAL.
For web-based distribution make sure the site is up.
Exchange 2013/2016 Exchange 2013/2016 will only be distributing the OAB via web-distribution. For all versions of Outlook (since 2003) you have two choices, either take Outlook out of cached mode* (so it queries the ‘live’ global address list).
