No items are displayed in Outlook after you install Exchange Server 2010 SP3 or Update Rollup 6 for Exchange Server 2010 SP2

Consider the following scenario:

• You install Microsoft Exchange Server 2010 Service Pack 3 (SP3) or Update Rollup 6 for Exchange Server 2010 Service Pack 2 (SP2) in an Exchange environment.
• Microsoft Outlook is running in online mode.
• You select a folder in Outlook.
• You add a To or Cc column to the folder view.

In this scenario, no items are displayed in the folder. However, if you remove the To or Cc column from the folder view, all the items are displayed in the folder.

Note This issue occurs only when the user profile does not use the Unicode format. For example, this issue occurs when the user profile uses the American National Standards Institute (ANSI) format. To determine which format the user profile uses, follow these steps as appropriate for the version of Outlook that you are running.
