This error occors sometimes in Outlook 2003 when trying to set the Out of Office Assistant. To fix this:

1. Open Outlook.
2. Click on Help -> About Microsoft Office Outlook.
3. Then click on Disabled Items on the bottom right hand side. Click on “Addin: outex.dll (outex.dll)” and click the enable button.

You can also delete the registry key “HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Resiliency” which does the same as the above but the first part is easier to talk customers through.
