outlook will not open since installing sp 2, verify switch

[Bryan]

Since installing sp 2, I can't open office to check my emails. It says that
the command line not valid and to verify the switch I am using. I have no
idea what to do.

Hi Bryan,
can you post the original error message?
Do you start your outlook via command line?
