I've reached my mailbox quota size. What can I do?

With 20i 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 20i. 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 My20i 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

To upgrade to a Premium Mailbox (50GB):

• Head to Manage Hosting > Options > Manage >  Email Accounts.
• Locate your mailbox with high usage
• Next to the mailbox, you should see the option to Upgrade to Premium Mailbox. This costs £39.99/$39.99 a year.
• Add the premium mailbox to your basket and check out where it will then apply. 
• The premium mailbox comes with a plethora of benefits, and these include:
  • A 50GB mailbox size by default
  • Discounts on further 10GB Quota addons costing only £9/$9 a year. There is no limit to how many you can purchase
  • The ability to save Contacts and sync them between mail clients using CardDAV
  • The ability to set and use Calendar events and sync them using CalDAV
  • Access to our improved Premium Mailbox Webmail Client with a new up-to-date, stylish theme, and hosted on our Premium mailbox servers that offer greater performance

To upgrade your mailbox to more than 10 GB:

• Head to Manage Hosting > Options > Manage >  Email Accounts.
• Locate your mailbox with high usage.
• Next to the mailbox, you should see the option to upgrade. To get an extra 10 GB storage costs £9.99/$9.99 for the year, less than 3 pence/cents a day.
• Select this and check out to increase the mailbox by an additional 10 GB.
• You can purchase as many 10GB upgrades for your mailbox as you want. There is no limit to this.

When should you use the Premium Mailbox or the 10GB Quota Addon:

Both a Premium Mailbox and our 10GB Addons are effective ways of increasing the space on a mailbox that requires more space to store its emails. Choosing the option that best suits the use case of the mailbox is important.

The premium mailbox is what we would recommend in the majority of cases. Not only does it provide 50GB of email storage space, which is more than enough for the majority of users not to worry about. But it also means that any further 10GB addons needed are at a discounted rate (the discounted rate is: £9/$9 per year). Furthermore, the benefits of syncing your Contacts and Calendar across mail clients, and the premium webmail are benefits that are too good to pass up! 

In comparison, the 10GB Quota Addons on their own only provide an extra 10GB of Storage space and no further benefits. This is useful for when you simply just need 10GB of space adding to the mailbox, and would not see any use from the other benefits that our Premium mailbox offers. 

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.
