Does my new Nokia device support subfolders in Mail for Exchange?

Yes, the built-in Mail for Exchange client on the Nokia devices (for example on E72, E75, E52, E55, 6730 classic, C5...) supports subfolders from your corporate Exchange account.  To view them in your Mail for Exchange mailbox:

3. Select More folders.
4. Select the subfolder you want to view.
