In a Microsoft Exchange Server 2007 environment, you log on to Microsoft Office Outlook Web Access (OWA)
Exchange Server 2007 is in multiple Global Category servers' environment.
You use the address book to perform a search operation
You receive more than 50 search results. These search results are distributed over several pages.
You click Next Page to view more search results and then try to change the display line for the search results.
In this scenario, you may receive the following error message:
Could not connect to a directory server. If the problem continues, contact technical support for your organization.
Note There are two display line buttons available at the top of the Address Book search result window. You can click any one of them to switch between a Single Line display and a Multiple Lines display.
This error message occurs because LDAP queries occur for the Address Book search. In the multiple GC servers' environment, the LDAP queries for the Address Book search may use a cookie. The cookie is issued by one GC server to communicate with another GC server when you change the display line for the search results.
To resolve this problem, install the following update rollup:
