Problem After Installing Exchange Server 2007 Hotfix KB2756497

After installing Exchange Server 2007 Hotfix KB2756497 (Update Rollup 8v2), clients are unable to connect to the server, Outlook repeatedly prompts for credentials and email is not delivered (if using the POP3 Connector on Windows Small Business Server 2011).

To resolve, start the following services: Microsoft Exchange Information Store and Windows SBS POP3 Connector.

Workstations may then need to close and re-open Outlook.
