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

• 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.
