One of the primary duties of the Administrator is to monitor the size of your users’ mailboxes to ensure that they do not exceed the size limit on the server. Once the mailbox limit has been exceeded by approximately five percent (5.0%), the communication to the Exchange mailbox will shut down and the users will no longer be able to send or receive email.
Users receive an Exchange system notification email when their mailboxes reach a pre-defined “warning limit.” Upon receiving such a warning, the mailbox needs to be managed by either utilizing the archiving features of Outlook or Entourage, or by increasing the mailbox size.
Administrators should routinely access the
Storage Usage Report in order to remain aware of users’ mailbox size limits and usage in order to effectively manage the total allocated storage space.
