I cannot work out how to change/set the event organizer on events I create on CalDAV calendars in Thunderbird v68. I have 8 calendars hosted on a single account Fruux, i.e. the same email address is used as credentials for all calendars and they are all sync'ed via CalDAV to Lightning. Most of the calendars are associated with the email address used to login to Fruux, but two are associated with other email accounts. Under preferences I've configured the email address for all the calendars to reflect the appropriate email account, I'm using "client side email scheduling" and all of the email accounts in question have appropriate/unique SMTP servers configured on Thunderbird. When I create an event in a calendar that uses an email address that is not the login email address for Fruux, the event is sent by the right SMTP server, from the right email address - which is what is expected - but the organizer configured in the ics invite is set to the email address used to login in to Fruux, not the email address I've associated with the calendar in preferences. How do I change this please? Or is this fixed in Thunderbird 78? Thanks for any help.
