AX 4.0 && Outlook 2007 on Windows 7

hello all,

i’m running AX 4.0 on windows 7. I keep getting this error message “Error executing code: The method has been called with an invalid number of parameters” when trying to send an email from outlook. i’ve tried the suggestions from this post below but it did not fix the problem.
