Microsoft Outlook 2003


Recommended Posts


I have a user using Outlook 2003 with Windows XP. The Out of Office Assistant was always working fine until suddenly it stopped. When she clicks on it now to open it the following error comes up - "the command is not available. See the program documentation about how to use this extension".

I checked the Add-ins Manager under Tools/Options/Other/Advanced and the Exchange Extensions property pages is selected.

I also removed the users profile and added it again but no change. I don't really want to re-install Outlook but I will if there are no other ideas?

All help appreciated, many thanks,

Delete reg key


or try

Outlook > Help > About > Disabled items

If you see Outex.dll, select it and then click the enable button.

Restart Outlook to see if it worked.

Good luck.
