webmail goes to Horde instead of mailenable

[riprod]

I ahve mailenable pro on the server but when a client logs into plesk and clicks on webmail it takes them to Horde. Not sure what it is but seams like a simple version of webmail.

The mailenable webmail is behind my site, how do I can the webmail link in Plesk to go to the MailEnable Web mail.

Thanks
