In general, Outlook will automatically update the Offline Address Book (OAB) for Exchange accounts once every 24 hours.
When it didn’t or when you want to make sure you do have the latest OAB available, you could manually trigger an update from within Outlook as well.
They are stored in the following location: which itself holds subfolders with named after Account GUIDs.
The easiest thing to do here is to create a new oab, forge generation, assign it to a mailbox database and force downloading of the oab in an outlook client to verify if that worked. 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. In the action pane select the New offline address book 4.
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.
I’m giving it a 99% chance that you will (and if you don’t you have a serious problem at hand!
) The reason you are not seeing these new users appear in outlook cached mode, but can see them in OWA, is because for one or another reason the offline address book is not generating properly. In the right pane you should see the default offline address list. Right click in the right pane and create a new offline address list. 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 7. Drill down the organization configuration, mailbox 3.
When you have multiple Exchange accounts configured, you’ll find a folder for each account that you have.
