How to fix Out Of Office Assistant problem

When you try to configure Out Of Office Assistant from the Tools drop down menu and you get the following error massage:

"The command is not available. See the program documentation about how to use this extension."

Microsoft Office Outlook disables the outex.dll because it's prevented Outlook from functioning correctly (Usually After Crush).

Solution 1:

• Open Outlook > Click on the Help option
• Select the About Microsoft Office Outlook option from the drop down menu.

• Click on the Disable Items button
• Inside the white box you will notice the outex.dll row > click on it to highlight it.

• Click on the Enable button.
• Close and restart the Outlook.

Solution 2:

• Remove the following registry key: HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\OFFICE\11.0\OUTLOOK\Resiliency
