E-mail is not a storage solution.
Best Practice: Inform the user that they must manage their e-mail inboxes and folders in order to create space (Delete old E-mails and setup Auto Archiving).
- If the user MUST have their e-mails archived they may do so by following instructions here:

If this solution is not satisfactory a select few users may be eligible for upgraded storage. *** Do NOT suggest this solution until consulting with an administrator. ***
