Every time I try to send mail from Outlook 2007 I get a 0x80070057 one or more paramaters are incorrect error message.

It seems to only happen when I select an e-mail address from the auto-complete list. I've tried clearing the auto-complete list with no success.

Any guidance or suggestions would be highly appreciated.

It's a memory error, I found this at Microsoft's Knowledge Base, check out the link below.

When was the last time you ran a Dick Clean-up, Error Check and Defrag? Just a thought, see second link and review 7 quick fixes.
