Solution using external Webmail service

Solution via command line

Connect via SSH.
Disable Webmail service in domain example.com:

# plesk bin domain_pref --update example.com -webmail none
Get IP address for webmail.example.com DNS record type A included in example.com DNS zone:

# plesk bin dns --info example.com | grep webmail
webmail.example.com. A 203.0.113.2
Remove webmail.example.com DNS record type A included in example.com DNS zone according to information provided in previous step:

# plesk bin dns --del example.com -a webmail -ip 203.0.113.2
In case Mail service will be managed externally, disable Mail service:

# plesk bin site --update example.com -mail_service false
Create webmail.example.com with forwarding hosting type as domain or subdomain:
- To create webmail.example.com as domain:
  
  # plesk bin site --create webmail.example.com -webspace-name example.com -mail_service false -hosting true -hst_type std -target_url http://example.info
