I have set up quotas in the Mailbox Store properties. The quotas that have been set up are not controlling the size of mailboxes. I have since read that there needs to be a policy set up to set up quotas properly. I created a policy in the system policies folder as a size quota policy. It has no values yet and the checkboxes for Issue Warning, Prohibit Send and Prohibit send and receive have not been checked. So it has not yet been engaged.
First question - is that correct about how to implement a quota using a policy?
Second question - If a policy is set up for lets say 500mb and some of the users have bigger mail boxes than that say like 750mb to 1000mb, what happens to their mail after the quota has been engaged?
