1851863 - Accepting an invitation shows it being accepted in every attendees' inbox

Status: UNCONFIRMED

(Thunderbird :: Message Reader UI, defect)

Description

[Kostya Orlik]

Attachment: 2 calendars enabled

Steps to reproduce:

User agent: Mozilla/5.0 (X11; Linux x86_64; rv:115.0) Gecko/20100101 Thunderbird/115.2.0

1. I have 2 mailboxes present with their coresponding personal calendars subsribed to during account setup (CalDAV, "su1 personal", "su2 personal"): [e-mail] and [e-mail]
2. To both recipients a calendar event invitation is sent. At this point only sameusers' subscribed calendars are enabled, "Home" calendar is not enabled (attach: 2 calendars enabled)
3. I accept an event in sameuser1's inbox inside 3pane mail veiwer (placing it to "su1 personal" calendar in an appearing dialog window), the invitation is set as "been processed", as it should be.

Actual results:

I view an invitation to the event in sameuser2's inbox inside 3pane's mail veiwer - an invitatin is alredy set as processed, yet sameuser2 had not previously viewed the invitation. Viewing this invitation's details, it is placed to "su1 personal" calendar, not "su2 personal", while being sent to and viewed in sameuser2's inbox.
Then, switching to calendar view, the invitation for sameuser2 was not accepted, only for sameuser1.

Same pattern is observed if I accept the invitation from the calendar view first - in 3pane view it is the same accepted invitation for both recipients, yet calendar view shows attendees statuses correctly (su1 accepted, su2 did not). And when accept an invitation from sameuser2 first, the details of su1's invitation show that the accepted invitation belongs to samuser2's calendar "su2 personal".

In case of multiple mailboxes being attendees to a same calendar event a workaround is to view invitations' statuses only from the calendar veiw.

Expected results:

When accepting an invitation for sameuser1, sameuser2's invitation should not be shown as accepted in 3pane view mail reader.
