How to change the default mailbox size in Plesk

Question

How to change the default mailbox size in Plesk?

Answer

For Web Host / Web Pro license editions

For Web Admin license edition

Command-line instructions

Changing the limit for one subscription

1. Log in to Plesk.
2. Go to Subscriptions > example.com.
3. Expand the sidebar, if it is hidden:
4. Click Customize under Account (in the sidebar).
5. On the Resources tab, set you value for Mailbox size.
6. Click Update & Lock.
  
  Note: The subscription will now be locked and will not be synced with its service plan.

Changing the limit for all subscriptions assigned to a service plan

1. Log in to Plesk.
2. Go to Service Plans > plan_name > Resources tab.
3. Find Mailbox size and set your value.
4. Click OK to apply the changes.

It is not possible to manage the default mailbox size via Plesk user interface in Web Admin license edition, because the main purpose of the license is to keep everything unlimited, except for the number of domains.

If the size has been changed previously (when Web Host/Web Pro license edition has been used), refer to the command-line instructions to change it.

Connect to the Plesk server via SSH (Linux) / RDP (Windows Server).

Note: On Windows Server, start a command prompt as an Administrator.
Update the default mailbox size of a subscription using the command:

# plesk bin subscription_settings --update example.com -mbox_quota 100M

where:
- example.com - website name
- 100 - new mailbox size
- M - unit in megabytes. Other options: B - bytes / K - kilobytes / G - gigabytes / T - terabytes
