When trying to use the Out of Office Assistant from the tools menu in outlook 2003 you receive a message stating : -

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

To resolve this problem you will need to re-enable the outex.dll addin/file.

To do this go to > Help > About Microsoft office outlook > Disabled items. Click on outex.dll and select enable.

Restart outlook and you should be good to go again!

When you try to open printers and faxes nothing happens. You have rebooted but this does not help.

2.)  Right click on Print Spooler and click stop.
3.)  Delete all files from C:\windows\system32\spool\printers\
4.)  Start the Print Spooler from services.
