Question

How to change the default mailbox size in Plesk?

Answer

 

For Web Host / Web Pro license editions

 

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.

 

For Web Admin license edition

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.

Command-line instructions

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

    Note: On Windows Server, start a command prompt as an Administrator.

  2. 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

    The fact that these important settings are only available in the side bar, which might be hidden, is a bit rubbish. Why not add Account as another tab – at least then you might have a chance of finding it. The expand/hide side panel button is so tiny, it does not reflect the importance of what is hidden behind it. 

    Your screenshots should include the expand side panel button, and you should explicitly mention the need to have this open.
