Current UH students are allotted 250 megabytes (MB) of storage and current UH faculty and staff are allotted 500MB of storage for their email.
The storage infrastructure is a finite, shared resource and your kokua (help) in using this resource wisely is appreciated. Before your storage usage reaches capacity, email messages will be automatically sent to you as a reminder to remove or archive email. Should you reach your maximum quota, you will no longer be able to receive mail. While it is possible to request larger quotas, technical support staff will ask to review your current email practices and where feasible make recommendations as to how best to adopt practices that make the best use of the existing resources. Your current mail quota status is now visible by logging into https://mail.hawaii.edu and viewing the quota graphic on the left side of the main mail screen.
Where previously we were able to back up mailboxes individually in order to facilitate individual restores, the current backup methodology provides only for disaster recovery restores in the event of a hardware or data center catastrophe. So if a customer accidentally deletes an email message, we will no longer be able to provide a custom restoration. This is consistent with practices at most universities.
The links under the Techniques to Reduce Email heading of this page will inform the user how to go about removing email from the server to create more available disk space. The user should follow the link that corresponds to their computer platform and email application.
Some clients have an option to "Move email to Trash", "Mark email for deletion," or "Delete message immediately." If your email client is configured to "Move email to Trash" or "Mark email for deletion", an additional step is required to remove the message from the mail server. Until then the email would still be recoverable and not permanently deleted. (Since it is still in one of your mail folders it is still counted toward your quota.) For instructions on permanently deleting these messages, please view the appropriate link under Techniques to Reduce Email below.
The user may also wish to backup their email folder off of their local hard drive. Follow the appropriate link under Techniques to Backup Email heading for instructions on creating a backup copy. Unfortunately, backing up email using Web Mail and MyUH Email is not possible.
