There are multiple ways to setup autodiscover.. A new way is defined in a new RFC, but due to Plesk's DNS bugs it is not possible to use them. eg, these commands fail:

# Plesk Parallels bug ID: PPPM-2640

/opt/psa/bin/server_dns --add -srv '' -srv-service _imaps -srv-target-host mail.X.nl -srv-protocol _tcp -srv-port 993 -srv-priority 0 -srv-weight 0
/opt/psa/bin/server_dns --add -srv '' -srv-service imap -srv-target-host mail.X.nl. -srv-protocol TCP -srv-port 143 -srv-priority 5 -srv-weight 0
/opt/psa/bin/server_dns --add -srv '' -srv-service pop3s -srv-target-host mail.X.nl. -srv-protocol TCP -srv-port 995 -srv-priority 10 -srv-weight 0
/opt/psa/bin/server_dns --add -srv '' -srv-service pop3 -srv-target-host mail.X.nl. -srv-protocol TCP -srv-port 110 -srv-priority 20 -srv-weight 0
/opt/psa/bin/server_dns --add -srv '' -srv-service submission -srv-target-host mail.X.nl. -srv-protocol TCP -srv-port 587 -srv-priority 0 -srv-weight 0

The Outlook way of using autodiscover requires SSL certificates on the autodiscover domain and is thus a bit more tricky to setup. Lets hope the autodiscovery using DNS gets quickly implemented in all mail clients.

I believe, as this DNS autodiscover is relatively simple, it should be sufficient to configure these records in the default-installation DNS template.

Maybe you know them from Microsoft Exchange...
It's the redirector wehn you set up an outlook or similar application..
If autodiscover is working, you just need to insert the eMail-address and the password, all other settings wcomes automatically
