When multiple address lists are included in the OAB, each address list is built as an OAB and is available for download to the Outlook clients. In this scenario, when Outlook receives the list of available OAB's, it does not necessarily download the one for the Global Address List by default.
To resolve this issue, set the Global Address List as the only address list for which an OAB is generated on the Exchange server. To do this, follow these steps:

For existing Outlook profiles, you can manually change the OAB that is downloaded to the one that is built from the Global Address List.
In Outlook 2010, the Choose automatically option was added as the default option for compatibility with the new multiple Exchange accounts feature.
