outcmd.dat is the toolbar customization file. It's only created when you
customize a toolbar in Outlook. While outlook will recreate it, its not
inconsequential or of little value to most people who have one.

There are other files that get corrupted more often - some are replaced by
outlook automatically, others are not. Users do not like it when outlook
deletes customizations, even if the file is bad. If they replace it
themselves, they can see that it really was corrupt and not just outlook
deleting files willynilly.

But would you agree that a simple pop-up letting the user know the
file is bad, and either giving them the choice to continue, or the
choice to exit and go fix it themselves, or the choice to erase it,
would be better development decision than to simply let the process
freeze up, requiring manual termination of the process and a lot of
head scratching wondering what went wrong? A freeze on start-up that
does not occur in safe mode first sends one down the path of looking
at add-ins, antivirus issues, recent windows updates and such. There
is no good excuse for just leaving them guessing due to a corrupt file
which is really inconsequential in itself anyway.
