inbox and sent items folder views -- make all the same

[superba]

I use a number of folders to organize received and sent mail. Right now
those folders have every type of folder view: inboxview, normal, messages,
etc. I want to make all the sub folders under inbox use the same view and to
make all the sub folders under sent mail the same.

Is there a way to do this without changing each and every subfolder
individually. BTW, I've changed a number of them manually one at a time and
for some reason the changes do not remain. They will be okay for some period
of time but eventually they revert back to what they were to begin with.

TIA.

Cheers!
