Unable to change mailbox size in Plesk GUI going to Domains > example.com > Email Addresses > Click on the mailbox > Another size. The following error is shown in Plesk GUI:
PLESK_ERROR: The specified limit is invalid.
Mailbox size typed in field Another size is larger than the value defined in the Default size of the subscription service plan:
- In Service Plan: Service plans > Service_plan_name > Mailbox size
- In Subscriptions: Service plans > example.com > Customize > Mailbox size
- In Resellers: Resellers > John Doe > Customize > Mailbox size
Mailbox size is limited by Subscription / Service Plan / Reseller's Service Plan settings.
Note: If access as Plesk administrator is not possible, contact Plesk server administrator to apply this guide.
Change the mailbox size limit for Subscription or for Service Plan or for Reseller. This depends on where the limit is configured in each specific case. There are 3 options:
Change limit in a Subscription:
Go to Plesk UI > Subscriptions > example.com > Account section > click Customize > Mailbox size and increase limit to desired size.
Change limit in a Service Plan:
Go to Plesk UI > Service Plans > choose required Service Plan > change Mailbox size.
Change limit in a Reseller:
Go to Plesk UI > Resellers > the name of the Reseller that owns the subscription, domain or client > Account section > click Customize next to Mailbox size and choose the preferable size.
