Make organizer of event configurable

[mnlipp]

Is your feature request related to a problem? Please describe.

Currently, the user creating an event in his calendar automatically becomes the organizer of the event.

Describe the solution you'd like

I have several email addresses, but I don't want to create a nextcloud account for each of them. I'd like to be able to associate a calendar with a specific email address (an address different from the email address associated with my login).

When I create an event and invite people, the organizer-email configured for that calender should be used (instead of the account's email) as from address for the invitations and for the "Organizer" entry in the invitations.

Describe alternatives you've considered

Creating a special account for the alternate email address. But this means that in all clients I have to configure another nextcloud account in order to subscribe to the calendar that uses this other email as organizer's email-address.

This makes sense from a user perspective. I can't tell how this could be implemented or if this causes any trouble with the CalDAV standards. That's something to figure out if someone picks this up.

I think it needs nextcloud/server#31029, but otherwise it makes sense to suggest to use the additional emails.
From what I can see groupware solutions allow to use registered email aliases.

@tcitworld : without being in depth in the details, this should not need an alternate Reply-To. It is important to me that the (default) email address associated with the account does not appear anywhere in the invitation. So "From", "Organizer", whatever should be set to the "organizer" email address configured for the calendar -- which means that a "Reply-To" shouldn't be necessary in the first place.

[tcitworld]

The linked PR is not about that, it's about allowing the DAV internals to work with emails other than the user's main one, the ones we now have in « extra emails » on the profile. Otherwise there might be incompatibilities in some places where the organizer's email is not allowed to do some tasks, such as sending invitations. The Reply-To email being different is only a consequence of these changes.

I second this feature, but for a different purpose:
I want to schedule events and then make somebody else responsible for it, meaning I want to delegate alle the required work to another user.

[tcitworld]

@wunschadresse There's a calendar delegation feature that currently misses an UI, see #2706

I second this feature. We all have different identies in different contexts. Having my entire calendar tied to the email in my nextcloud account defeats the flexibility offered e.g. by thunderbird.
Having multiple nextcloud accounts, each for one identity, means 3 calendars, 3 configs etc. And it is not intuitive. So in the name of data protection, the organizer for calendar invitations should be editable.
