Monitoring the size and growth of Exchange mailboxes is an important part of your job. ScanIt from Netmail gives you a quick overview of your Exchange system, including the size of your mailboxes, folders, and email attachments. ScanIt also provides statistics for the busiest mailboxes in your organization so you can monitor usage patterns and prevent mailboxes from growing out of control. With ScanIt, you can also create smart reports.
Currently in beta, ScanIt is fully compatible with Exchange 2010, Exchange 2013, and Office 365.
