accessing outlook data using excel macro
 

Hey all,
I'm very new with all of this, however, my problem is this:
I have a bunch of data in excel which I then want to compare to certain
"task" fields in outlook (ie. the "Due Date" column in Tasks for example),
then update those outlook fields with new data. I was able to do it in an
Outlook macro, but not in the Excel macro. I get a "User defined type not
defined" error when trying to define a namespace variable as
"Outlook.Namespace"
Any help would be greatly appreciated. Thanks.
