Outlook gal not updating in cached mode sccm 2016 collection not updating

This should resolve the issue with users not showing up in Outlook when in cached mode.When you have Cached Exchange Mode enabled, Outlook by will by default cache the main Global Address List as well.In addition to this there a a few methods by which your Outlook clients get the offline address book.*Note: Unless you are NOT in cached mode.Outlook 2003 (and older)* clients get their OAB from a public folder, Outlook 2007 (and newer) clients can get their OAB from 'Web-based distribution' (basically form the website on the Exchange (or Exchange CAS) server.If the update mechanism appears to be broken for you, it could be because of a corruption in your OAB or in your mail profile.

Is there any way I can force a manual update of the Offline Address Book (OAB) in Outlook or reset it completely otherwise?

Alternatively you can increate logging on the MSEXCHANGESA\OAL Generator to see if the new address book generated successfully. Give the OAB a name, select a generation server (in case of a CCR this needs to be the active node) 5. When presented with the distribution points page enable the web base distribution and, in case of outlook 2003 clients, enable the public folder distribution. Once the wizard has completed, right click the new OAB and select to generate the OAB. Now drill down to the mailbox database, right click it and set the new OAB to be the default for that database. Open outlook with a mailbox that is residing in that mailbox database 10.

In outlook, click on the down arrow next to Send/receive. Note that if asked, you should select to download the entire address book and not just the changes.

The key issue here is that there are new users added to the directory but they are not showing up in outlook.

Now, if you are like most organisations then outlook will be operating in cached mode.
