I might have a problem with my Offline Address Book in Outlook.For me, new colleagues are not showing up and the contact pictures aren’t displaying either.Prompt before for full download As the OAB can be quite large in some environments, it could be wise to be prompted when Outlook wants to download the full OAB.

When you have Cached Exchange Mode enabled, Outlook by will by default cache the main Global Address List as well.

This is called the Offline Address Book and is being generated on the Exchange server.

Even though Outlook is the last in the chain, it is often the first level where the troubleshooting takes place as usually this is where the request is coming from.

And since this website’s main focus is on Outlook, it makes sense to start with Outlook as well ;-).

The command for the manual update procedure can be found here: Outlook will automatically download updates only unless the size of the changes is larger than 12.5% (one-eighth) of the total OAB size.
