Did you upgrade from outlook 2000? That file is for net folders, which were
removed beginning in 2002.

Find and delete extend.dat - see

I had to reload MS Office 2007 after reloading the Vista Operating system
on
my Dell laptop due to a malfunction of virus. After reinstalling Office I
received the following message when trying to open Outlook: The extension
configuration file "C:\program files\MS Office\Office\Addins\fldpub.ecf"
cannot be installed. There is an error in the syntax or format of the
file.

Also, when I tried to install Outlook again by selecting Add or Remove
Features on the installation disk, it shows MS Outlook with a red X which
means, "Not Available".

Does anyone have any ideas on how to fix this problem?

Thanks,

...FSM
