Plesk sets 100M by default for each email account, but most of the time, it is necessary to increase this value.
To be able to increase our space, first, it is necessary to access our Plesk panel.
Once inside, we will go to Subscriptions >> access the subscription of the email account and then to the Mail window.
Now the email accounts will appear, so we must click on the email account on which we want to increase the size.
From this new section, we can select the space, keep in mind that the other size section CANNOT be greater than the Default size.
In case you need to increase the default size, continue with the guide.
Once inside the Plesk panel, we go to the subscription and in Websites & Domains, in the right section of Account, we will click on Customize.
Now we must scroll and select the new default size or set it to unlimited.
Once changed, we only need to Apply changes.
