To resolve this you can disable Outlook cache mode, however this will remove the benefits it provides.
Another option is to only disable the Global Address List from being included, so it will also be a live copy from the exchange server.
Therefore, if you are working in Cached Exchange Mode and if you are working online — that is, your connection status is Connected to Microsoft Exchange — Outlook uses both the offline address book and the GAL to provide a complete listing of user information.
If you are in Cached Exchange Mode and your connection status is Disconnected, Trying to Connect, or Offline, you can see only the information that is in the offline address book.
It should be noted that mobile users should be avoided from this registry edit as they won’t have an address book otherwise (while working offline)!
I am active on Experts Exchange & Tech Net forums and I am a technical author for Search Exchange.The following registry settings can be used to disable the Global Address List from being included in the cache.Please note, this should be avoided for laptop/mobile users, as it will result in the Address Book being unavailable when working in Offline Mode.Note: If you're using Cached Exchange Mode, we recommend that you download the full details of the offline address book.This reduces the number of times the Outlook window might become unresponsive and the number of unnecessary connections to the Microsoft Windows Server Active Directory.
