PROBLEM:
When you try to start the Out of Office Assistant an error message appears which says: "The command is not available"
SOLUTION:
- close Outlook (also press ctrl-alt-del and start the task manager and end all running Outlook.exe processes)
- start regedit and go to: HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Resiliency
- rename "Resiliency" into "Resiliency_old"
- close regedit and start Outlook
