With SIRSTEVEHQ CP all mailboxes have 10 GB of data storage. It's unlikely that you should ever fill this unless you're receiving a large amount of mail or have a lot of emails with large attachments.
All the emails and attachments you have in your mailbox are stored on a server, and each mailbox is given a specified amount of space on the server, 10 GB in the case of SIRSTEVEHQ CP. Once that space has been filled by emails and their associated data, you will no longer be able to receive emails.
To check your mailbox usage:
- Log in to SIRSTEVEHQ CP and go to Reports > Mailbox Usage.
- Locate your mailbox and the usage will be displayed next to it.
Note: The storage shown on this page is only updated periodically. For the exact storage usage continue the following steps:
- Click on Manage.
- Locate the mailbox on the page you are redirected to.
- Select Options > Webmail.
- The current, up to date, usage will be displayed in the bottom left.
Steps to free up more space in your mailbox:
- Delete emails from your Trash folder. When emails are deleted from your inbox or other folders they will go to your trash. These emails are still accessible to you and are recoverable but are still taking up room on the server and so are using your mailboxes storage space. Once you delete emails from your trash they are gone completely. After this they’re no longer recoverable so only delete emails you’re sure you don’t need.
- Create a local backup of your emails. This will depend on the mail client you are using to view your emails, but most modern mail clients include an option to create a backup of your mailbox which you can then hold on to your computer. You can find a guide to doing this in Outlook here.
- You can also remove your sent emails if you no longer need a copy yourself. Deleting emails from your sent folder will not remove them from the recipient's inbox but will free up space on our server for your mailbox
What Happens When a Mailbox is Full?
When your mailbox reaches its storage limit, any new emails sent to it will be rejected by the server. The sender will receive a bounceback message letting them know the email could not be delivered.
These undelivered emails are not stored or queued — they are permanently lost unless the sender resends the message after you've cleared space in your mailbox.
To avoid losing important emails:
- Regularly delete old or large messages.
- Empty your Trash and Spam folders.
- Consider upgrading your mailbox quota if you're consistently hitting the limit.
