Now, if you are like most organisations then outlook will be operating in cached mode.So log in to OWA and test if you can see the new users there.We have a number of laptops in the organization, and I've noticed that it takes a long time to updated everyone's GAL on their laptops (in cached mode) when I add a new distro group or user.The current situation, I've created a new distro group, but has yet to show up in my GAL on my laptop (cached mode of course).This situation however is extremely rare since the default maintenance time on Exchange is at AM and updates and downloads are usually performed during working hours.
The problem you are facing is that by default the OAB is updated once per day.
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.
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.
