Yes, you will still need a CAL for these users (or their devices, depending on your user/device CAL setup), since they are using an Exchange mailbox and communicating with the Exchange Server. They will also need a Windows Server CAL, unless of course the users in question already have a user CAL for when using the general network resources.

You can manage folder sizes using Mailbox Manager, a feature which is set as part of recipient policies. You can set which folders to process, what to delete based on size and age criteria and a few other things. There's a few steps on how to do it in the lower part of
