Question
How to change the default mailbox size in Plesk?
Answer
Changing the limit for one subscription
-
-
Go to Subscriptions > example.com > Customize (in the right pane).
-
On the Resources tab, set you value for Mailbox size.
-
Click Update & Lock.
Note: The subscription will be locked for synced with its service plan.
Changing the limit for all subscriptions under a service plan
-
-
Go to Service Plans > plan_name > Resources tab.
-
Find Mailbox size and set your value.
-
Click OK.
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.
The only way to manage the default mailbox size is via a command-line interface with administrator privileges.
Examples (for Linux and Windows Server):
-
Set the default mailbox size to 100M:
# plesk bin subscription_settings --update example.com -mbox_quota 100M
-
Set the default mailbox size to the default value (Unlimited):
# plesk bin subscription_settings --update example.com -mbox_quota -1

I applied the command but in the panel there is always the default limit. How can I fix it?
Hello,
There is not enough symptoms to analyze the issue. That is why it is needed to narrow down it:
Please enable debug logging for Plesk using one of this articles:
- For Windows:

- For Linux
https://support.plesk.com/hc/en-us/articles/213408889-How-to-enable-debug-mode-in-Plesk-Onyx-and-earlier-versions-for-Linux-
Then execute the command mentioned in this KB:
After that try to analyze the output or send it to us here for analyzing.
Note: default value for subscription is inherited from its service plan
Am I wrong or does this KB not belong to "Web Admin Edition"?
Then Please tell me where to find subscriptions and service plans?

That notice is for cases when the license was downgraded to "Web Admin Edition"
if i do:
plesk bin subscription_settings -u mydomain.es -mbox_quota 9GB
i get:
SUCCESS: Update of domain 'comunicavalencia.es' completed.
When i now got to Mail -> Email Addresses
i get: the specified limit is invalid.
when i do now in command line as root:
plesk bin subscription_settings --info comunicavalencia.es
i get:
mbox_quota 0 KB Mailbox size
So it looks like that the server mailbox_quota has to be >= like a subscription/somin mailbox_quota
What do i have to do to change the mbox_quota for the subscription?
I tried:
plesk bin subscription_settings -mbox_quota -1
But that doesn't work
Thanks in advance, Martin
i had to change firts the server mailbox_quota, which was set to 0.
it worked with this manual:

Hi, @Martin!
Thanks for sharing.
@Robert
I can't see this information...
Please explain. thx

As you know there are no Service plans in Web Admin Edition.
When you add a new domain Plesk creates a webspace for it(webspace is equivalent of subscription in Web Pro and Web Host Editions)
The default mailbox quota for any webspace in Web Admin Edition is unlimited.
You can check all the default settings for a webspace with the command:
plesk bin subscription_settings --info example.com
I just used the migrator to migrate from one server to another one. The old one has unlimited default mailbox size, but the new one has 100MB for some reason. Several of the imported mailboxes use more than 100MB and I don't have root access. I'm in desbelief that you can't change this setting from the GUI or that at least it was not set the same as in the old server. Really bad.
An error occured while updating domain settings: The following option is applicable to subscriptions only: mbox_quota
Hi there Ian Potter
If you change mailbox quota using the command:
# plesk bin subscription_settings --update example.com -mbox_quota
you need to specify the name of a webspace (main domain), not additional domain.
