Disabling PST creation

After you have centralized, sorted, and archived the PST files you already have, it is a good time to disable the creation of PST files and addition of new mail items to existing PSTs. This will prevent any complications relating to users creating PST material while you are in the processing of collecting PSTs which would lead to incomplete results.

Communicate to your users the appropriate timelines about your plans to set a new policy for disabling PST creation, and enact the policy before proceeding.
