Note The Microsoft Exchange server generates updated offline address book files at a 24-hour interval. Right-click the default OAB, and then select Properties.Ĭlick to clear the Include the following address lists check box.Īfter you make this change on the Exchange server, any new Outlook profiles that you create will use the OAB with the GAL by default. To resolve this issue, set the GAL as the only address list for which an OAB is generated on the Exchange server. In this scenario, when Outlook receives the list of available OAB's, it does not necessarily download the one for the GAL by default. 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. This can also occur in Outlook when the When opening the address book, show this address list first option is set to Choose automatically. This behavior may occur if multiple address lists are included as part of the Offline Address Book (OAB) generation on the server that is running Microsoft Exchange Server.
