Is there any way I can force a manual update of the Offline Address Book (OAB) in Outlook or reset it completely otherwise?In general, Outlook will automatically update the Offline Address Book (OAB) for Exchange accounts once every 24 hours.Most home and personal accounts do not use Microsoft Exchange. The Offline Address Book contains the properties of a user, such as e-mail addresses, that Microsoft Outlook requires in order to send an e-mail message and display information about the user.By using the Offline Address Book, Outlook does not have to connect to Exchange in order to resolve names or open the records for each user.For me, new colleagues are not showing up and the contact pictures aren’t displaying either.They do for my colleague sitting next to me, so I don’t think it is a server misconfiguration or something like that.
If Outlook is left running constantly in Cached Exchange Mode, it updates the Offline Address Book automatically about once a day, depending on Address Book updates on the server running Exchange.
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.
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.
