When you start your Hosted Exchange account, you are allocated 500 megabytes of storage space for each mailbox that you order. This means that the server will store up to 500 megabytes of email information, including the email itself, and any attachments.
Strategy
If you want to limit the amount of disk space you are using, there are a variety of ways that you can archive mail information on your computer. It is a *good* idea to have back-ups. At the same time, leaving mail on the server can have its advantages, including the fact that you need to leave the mail on the server in order to access it through Outlook Web Access or Outlook Mobile Access.
See the Backup Strategies topic for more information.
Accessing the Storage Space Feature
To access the Storage Space feature:
Log in to ControlPanel, click the Email link, then click MS Exchange, and then click the Storage Space link.
The Summary screen displays, which allows you to re-allocate your disk space, by adjusting the amount of space that each mailbox has. You can also add additional disk space.
