Mail disk space usage is incorrect in Plesk

Symptoms

Mail usage for the mailbox does not appear to be correct at the Plesk > Domains > example.com Mail > Mail Accounts page.
The correct mail usage is shown when the mailbox is viewed through any webmail or email client.

Cause

The Daily Maintenance task that is responsible for the calculation of the mail usage has not been executed today, due to which the information about the mail usage has not been updated today.

Resolution

Wait until the next Daily Maintenance script execution time is reached or recalculate the mail usage manually:

Via Plesk GUI

Via SSH (Linux)

Via RDP (Windows)

Log into Plesk
Go to the Domains > example.com > Mail > Mail Accounts page and press the button that is next to the Usage column:

- For all domains:
