User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:48.0) Gecko/20100101 Firefox/48.0 Build ID: 20160817112116 Steps to reproduce: I setup 4 calendars in the office. - 2 caldav calendars (private/work) from my owncloud server at home - 2 from a intranet WebdayDAV Server (national holiday/absence of colleagues) using ics files. I send invitations from each calendar. Actual results: For the ics calendars everything is fine, the e-mail address I configure (calendar.registry.<ID>.imip.identity.key) will be used. The invitations I send from the CalDav calendars ignore my configuration. They use the e-mail address that is configured for the owncloud admin (=me). I do not use this e-mail address in thunderbird at all - it is reserved for admin tasks of owncloud. Expected results: Lightning should use what is configured, no matter whatsoever information is probably passed through the CalDav protocol.
Please don't report issues more then once.
