Since Plesk Obsidian RC4, users’ Microsoft Outlook and Thunderbird mail clients can now be automatically configured based on entered emails.
Plesk is now an old system and just a only some few update have been done !
The is no SSL/TLS domain by domain, just only one SSL for the server name.
There is no Autodiscover and many features are missing !
That's a big challenge to use Plesk, my customers are always complaining and it gives me many troubles.
Customers Support always saying "we are working on" but nothing is coming...Very very disappointed...
