Microsoft Outlook 2010 is configured to access a Microsoft Exchange Server 2010 mailbox with an Exchange cached mode profile.
You create a new meeting and use the Room Finder feature.
The room lists are displayed but under Choose an available Room the conference rooms are not displayed.
The offline address book (OAB) is generated by Microsoft Exchange Server 2003 or Microsoft Exchange Server 2007. In order for the Room Finder feature to work, the OAB must be generated by Exchange 2010 or a later version.
Use the following steps to reconfigure the Exchange servers so that Exchange Server 2010 is generating the OABs:
Move the OAB generation from the older version of Exchange server to an Exchange Server 2010 mailbox server. Depending on the versions of Exchange Server in your environment, please go to the following Microsoft web sites for more information:
In Outlook 2010, verify that the new OAB is fully downloaded and working successfully. To download the address book, follow these steps:
On the Send/Receive tab, click Send/Receive Groups, and then click Download Address Book.
In the Offline Address Book dialog box, make sure that the Download changes since last Send/Receive check box is checked.
Schedule a meeting and use the Room Finder feature to verify that the list of conference rooms are available.
The issue does not occur when you use an Online mode profile.
