Outlook 2003 Out of Office Assistant Error: “The command is not available. See the program documentation about how to use this extension”
Outlook 2003 March 19th, 2008
I recently came across the following error message when one our users attempted to enable their out of office message in Outlook 2003:
Out of Office Fix
To fix this problem you will need to perform the following:
Shut down Outlook and open Windows Registry via Start->Run->regedit
Then find the following node:
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Resiliency
Export the entry key listed under this node(just in case) and then Delete afterwards.
Relaunch Outlook and you should be able to set the Out of Office.

@Roman - check if Outlook disabled the addin. You can do this by following the steps on this post:
