Attachment: ics_error.png

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36

Steps to reproduce:

Send an e-mail with the following ICS file
BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Sabre//Sabre VObject 4.1.2//EN
CALSCALE:GREGORIAN
BEGIN:VEVENT
UID:sabre-vobject-d4b1ccb3-2197-4ee4-aab8-7bc2516adbf8
DTSTAMP:20170123T182612Z
SUMMARY:testev2
DESCRIPTION:
DTSTART;TZID=Europe/Athens:20170214T090000
DTEND;TZID=Europe/Athens:20170215T170000
LOCATION:
ORGANIZER;CN=Organizer Name:mailto:[e-mail]
ATTENDEE;CN=Test User:MAILTO:[e-mail]
END:VEVENT
END:VCALENDAR


Actual results:

Thunderbird (with Lightning extension on) will receive the e-mail, the ics file will be parsed, a table will be rendered and the table title will contain the message: 
"Test User <[e-mail]> has accepted your event invitation"


Expected results:

It should not display "Test User <[e-mail]> has accepted your event invitation" since no such info was provided

Does the problem still exists when using the latest release build (Thunderbird 45 with Lightning 4.7) or the latest beta build (Thunderbird 51 with Lightning 5.3)? Do you get any error messages in Error Console?

Comment 3

[axaros]

Yes, the problem persists in Thunderbird 45.6.0 and Lightning 4.7.6
You will have an answer about the Error Console ASAP.

Comment 4

[axaros]

No, the error console is not showing anything when loading the message.

Can you please the entire received email and not just the ics part? If you want to modify sensitive information for privacy reasons, please make sure you don't change any information structure therein.

Can you please elaborate what you are trying to do - this is not fully clear to me based on this report, the examples and the stackoverflow posting.

If this is intented to be an home grown invitation email, a recipient should or could respond to, you must add a METHOD property specifying the respective method according to RfC 5546 as a child property of the outer VCALENDAR container and also change the Content-Type header in the email as per RfC 6047 to

Content-Type: text/calendar; method={your method goes here}; charset=UTF-8

to enable the calendar client to interpret the incoming message correctly.

Second, the string you mentioned will only be displayed if the METHOD is explicitely set to REPLY in the received email, but based on your examples, it is not. So please also cross check, whether the examples you provided are matching with your observations.

And finally, please retest with the current TB 52 beta (and the bundled Lightning).
