If you are using Summersault's new control-panel based hosting infrastructure (setup after May 2007), follow these steps:

1. Log in to the control panel for your hosting account
2. Under the "Email" section, click on "Manage Accounts"
3. Click on the "Quota" link next to the account you want to update
4. Enter a new quota amount, and click "Change"

NOTE: If you are using Summersault's conventional hosting infrastructure (setup prior to June 2007), you must contact Summersault to have the mail storage quota for an account raised or lowered. Note that increasing the quota for an account may incur additional charges.
