Webmail Shows Internal Server Error: User is Over Quota.

 

Internal Server Error User ‘username’ is over quota.

When you login to webmail, it’d show you an error as asbove. To correct the issue it’s necessary to extend the defined disk quota of the user account. Ensure the e-mail account and the cPanel account as an entire have sufficient space. However, there are times you would possibly see a error even if the accounts are under the limits. in this case, try for the solution as below:

root@server[#] cd /var/cpanel/overquota
root@server [/var/cpanel/overquota]# mv username username-bak

Confirm that you replace the username with the actual cPanel username.

When you login to Webmail the next time the error should get disappear.
