Thanks for the information! Unfortunately I'm not that experienced with VB.
I've looked at the code from the links you gave me and below is what I have
written on my own. I keep getting the error [Collaboration Data Objects -
[MAPI_E_NOT_FOUND(8004010F)] when I run the code below.
If I change:
Set objField = objFields.Item(CdoPR_AGING_FILENAME)
to
Set objField = objFields.Item(CdoPR_AUTOARCHIVE_TYPE)
or any other value it works.

I know I'm asking alot but does anyone have some sample code or could modify
my code below that would apply archive settings to a folder or all folders
in a mailbox with the values I chose? It seems I keep missing things I think
a savvy programmer would catch and could do much faster than I could ever
hope to.

Thanks again for all your help! I really appreciate it!
