When trying to browse through OWA Address Book on a default EBS configuration, first page of address book’ll load, but attempts to browse to subsequent pages’ll fail with: Could not connect to a directory server. If the problem continues, contact – technical support for your organization. This error occurs because default “Microsoft Exchange Server Publishing: Outlook Web Access” web site publishing rule’s configured for link translation by default. This allows first page to load successfully when internal OWA URL is translated, but subsequent pages’re unable to connect as cookie session fails to query correct URL. Disabling mapping for OWA web site publishing rule’ll remedy this situation, and doesn’t otherwise affect OWA functionality. Resolution.
