Creating a domain example.com that was previously removed returns the following error:
PLESK_ERROR: Error: Unable to load object of type BsDomain with id=148: Domain does not exist.
Domain webmail.example.com exists in Plesk
- #PPPM-11411 "The error message that appears when domain creation fails because a subdomain with the name ‘webmail.' already exists in Plesk now clearly states the reason for the failure."
- Plesk Obsidian 21 January 2020
If update is not possible for some reason you may try the following
Disable webmail in Plesk > Service Plan > <service_plan> > Mail > uncheck Webmail
Create the domain again in Plesk > Domains > Add domain Using the Service Plan with disabled Webmail.
