Exchange Quota

Most mailboxes have a maximum size limit. When your mailbox reaches its limit, you won't be able to send new mail until you delete some existing content in your mailbox. You may also be unable to receive new mail depending upon your quota limit.

You are allocated 10GB of total storage on the Exchange server for your mailbox, calendar, contacts, tasks and notes. When your storage approaches the 10GB limit, you may be unable to send and receive new mail until you permanently delete some of your existing content on the Exchange server. After logging in, follow the steps below to determine your quota usage.
