How Do I Change the Size of an Email Account?

Introduction

If an email account is full or needs more room, you can change its quota from cPanel. This lets you increase or reduce the storage assigned to a specific address, like info@yourdomain.com.

Steps to change the account size

In this video we walk you through the process step by step:

In summary:

1. Log in to cPanel with your credentials.
2. Open Email Accounts.
3. Find the account you want to change in the list.
4. Click Manage.
5. Adjust the storage quota based on the space available in your plan.
6. Click Update Email Settings or the equivalent button in your cPanel version.

What to keep in mind before increasing the quota

Increasing an email account’s quota doesn’t increase your hosting plan’s total space — email uses space from the same service, so it’s worth checking your overall disk usage. If an account is full because it has accumulated many old emails or large attachments, it’s also a good idea to clear out the inbox, sent items, spam, and trash.

Useful tips

• Use IMAP if you want your email synced across several devices.
• Empty the trash and spam folders regularly — many users delete emails but don’t empty the trash, so the space stays used.
• If an account receives a lot of attachments, download and archive important documents outside the mailbox.

Common problems

The account still shows as full after increasing the quota

Your email client may take a moment to refresh the information. Also check whether your hosting’s total disk space is full.

I can’t assign more space

Your plan may not have enough available space. Check your hosting’s overall disk usage.

Emails bounce with “mailbox full”

The account has hit its limit. Increase the quota or free up space by deleting unneeded emails.

Frequently asked questions

Can I set an email account with no limit?

It depends on your cPanel options and your plan’s limits. Even if an account has no specific quota, it will still depend on your hosting’s total space.

Does changing the quota delete emails?

No. Changing the quota only modifies the space allowed for the account.

Conclusion

To change the size of an email account in cPanel, open Email Accounts, find the address, click Manage, and adjust the quota. If the problem keeps happening, check your disk usage and clear out old emails.
