This article will illustrate how to change the mailbox quota of a mailbox using Exchange Services. Here are a few things you should know before continuing.

**Please Note: Depending on the access type of that mailbox, quota additions WILL be billable to your account. Once the changes are submitted, it will take up to two hours for the mailbox to increase or decrease its quota.
