How to Adjust Email Quota in cPanel

When creating email accounts in cPanel, users can set the email quota (mail storage) for each email account. It can also be adjusted manually if a user expects an influx of incoming emails or is about to exceed the allotted quota.

Shared hosting plans allow unlimited disk space, bandwidth, and email quota; VPS or Dedicated hosting plans, however, must be mindful not to exceed their allotted resources.
