Cause

An incorrect binding for Webmail with HTTPS support exists in MailEnable entry in IIS.

Resolution

1. Connect to the server via RDP.

2. Go to IIS Manager > Server_name > Sites > MailEnable WebMail / webmail(smwebmail) > Bindings.

3. Check all records related to Port 443 via webmail.example.com > Edit.

   Note: All bindings must have valid certificates.
   If any of them has Not selected entry in SSL Certificate field, then Default Certificate/Parallels Panel certificate should be set.
