In a cPanel server, you can't directly change the email storage to a specific size such as 5 GB, 10 GB, or unlimited. Email storage is typically determined by the available disk space on the server/Account. However, you can set email account quotas to limit the amount of storage that individual email accounts can use.
To set email account quotas in cPanel, follow these steps:
1. Log in to your cPanel account.
2. Navigate to the "Email" section, and click on "Email Accounts."
3. In the "Email Accounts" section, you will see a list of your email accounts. Find the account for which you want to set a quota and click "Manage."
4. Scroll down to the "Mailbox Quota" section. Here, you can set the quota for the selected email account. You can specify the size limit in megabytes (MB) or gigabytes (GB). For example, if you want to set a 5 GB quota, enter "5000" in MB or "5" in GB.
5. Click the "Save" button to save your changes.
Repeat these steps for each email account if you want to set different quotas for multiple accounts. Keep in mind that the total email storage on your server is limited by the available disk space. If you want to increase the overall email storage capacity of your server, you may need to contact your hosting provider and request additional disk space.
It's important to note that offering unlimited email storage is not recommended as it can lead to resource and performance issues on the server. Instead, consider setting reasonable quotas for your email accounts based on your available server resources and needs.
