Issue Plesk Premium Email is currently required to use Collabora Online

[nicolasP]

Server operating system version

Linux

Plesk version and microupdate number

Plesk Obsidian 18.0.47

Hello,
I want to install Collabora Online to use along with Nextcloud and I don't understand the technical reason that I would need Plesk Premium eMail to do so.
It's particularly strange as the Plesk Premium email apps would be the same as in Nextcloud...
How can I set Collabora Online without installing Plesk Premium email ?

Thanks

You will need 2nd server for that.
