Out of office assistance in Outlook 2003 disabled

In Outlook2003, sometimes the “Out of office” assistant can get disabled?

When the menu Tools>Out of Office Assistant is clicked an error message is displayed:

“The command is not available. See the program documentation…”

Resolution

Outlook likes to disable add-in’s if it thinks it is causing a problem.

In Outlook go to Help, select > about Microsoft Outlook. Select disabled items. Out of office assistant is in the dialouge box, and enable it.

This should now allow to enable the Out Of Office assistance.
