The mailbox is present in MailEnable, but it is not fully configured and its status is disabled.
All emails are bouncing from the mailbox.
There are two possible causes:
MailEnable Prevent simple passwords security policy is enabled. This prevents passwords from being set for the mailbox along with the mapped email address.
MailEnable configuration is broken.
In the MailEnable Administration console, navigate to Servers > localhost
Right-click on localhost and access Properties
Go to the Policies tab. If it is absent, contact Plesk technical support . If it is present, proceed to the following steps:
Disable Prevent simple passwords option
Rebuild the mail configuration:
"%plesk_bin%\\mchk.exe" --all --fix=all
