Description

[[e-mail]]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20170201180315

Steps to reproduce:

I deleted a meeting on my calendar that was organized by somebody else.


Actual results:

A meeting cancellation notice was sent to everybody on the meeting invitation.


Expected results:

Only a decline notice should have been sent to the meeting organizer.  Nobody else on the meeting should have been affected.  I was NOT the organizer.

What exact Lightning version are you on (look at the TB addon manager to get the information)?

Can you please describe your account/identity/calendar setup in detail?

Please answer also the following additional questions:
Are you also managing the calendar of the organizer of that event within Lightning?
Do you have associated the email identity you received the invitation for to a calendar managed in Lightning (see the calendar's propoerties in the calendar list of the calendar view)?
Are you storing sent and received emails in the same folder for the respective account you received the invitation in?

Of course.  I'm happy to help any way I can.

Thunderbird version is 45.7.0
Lightning version is 4.7.4

My configuration is a little goofy because of the restrictions my company puts on the Microsoft mail server.  They only have Exchange enabled, no POP3, IMAP, etc.  So, I am running DavMail to connect to the Outlook Web App (OWA) HTTP location.  It then translates to POP3, IMAP, etc. for Thunderbird.  I then have Thunderbird connected to localhost (DavMail).  I tried "Provider for Microsoft Exchange", but I didn't know the Exchange host to use.  "ExQuilla for Microsoft Exchange" auto-discovered a server and worked, but was really slow (on the order of taking an hour to download 100 e-mails).  So, I've been using DavMail since.

The calendar protocol in DavMail is called CalDAV (http://localhost:1080/users/[e-mail]/calendar).  That's what Lightning uses to get the calendar.  I also applied the tweaks recommended by the "Calendar Tweaks" (v.6.3) plugin.

Here are the answers to your specific questions:

Are you also managing the calendar of the organizer of that event within Lightning?
No.  I didn't even know the person until I had to confess that I had cancelled her meeting and that the cancelation had gone out to over 1000 people!  :-)

Do you have associated the email identity you received the invitation for to a calendar managed in Lightning (see the calendar's propoerties in the calendar list of the calendar view)?
Yes, I believe so.  When I open the calendar properties, the "E-Mail" field has my e-mail address in it.  It looks like the options are my e-mail address or "None".  I assume that is how it sends the organizer an e-mail when I accept or decline meetings.

Are you storing sent and received emails in the same folder for the respective account you received the invitation in?
I think so.  I checked the box that says to keep sent e-mails in the same folder as the e-mail I'm replying to.  However, when I send a new e-mail, it goes to the "Sent" folder.

Please let me know if what I'm saying doesn't make sense or if you have more questions.  Thank you for looking into this.

Is the event still in your caldav calendar or was it removed when replying? If it still exists, please attach it to this bug.

Also, can you attach the originally received invitation email and the sent out reply to this bug?

You can modify sensitive information within the email or the ics for privacy reasons, but please don't change the information structure of these.

Additionally, as you seem to have access to the davmail installation, do you still have the davmail logfile available which was written when receiving the invitation and sending out the reply and conatins any details to the conversion? If so, can you please attach that as well?

It was removed from my calendar.  Sorry.
I also searched everywhere for the original invitation, but cannot find it.
The DavMail logs for that time are not interesting:

The only thing I could find from the original transaction was the cancellation message Thunderbird sent to everyone.  I've pasting the message source below.  I did not see anything below that seemed super sensitive, but please update this post if you see anything.  I don't want to get in trouble with my company.

Comment 6

[[e-mail]]

I tried to reproduce this problem with a couple of friends here at work, but could not.  I went to one friend and had him send an invitation to me and someone else.  I then deleted the request from my calendar.  It sent the meeting organizer a decline note, as I would expect it to.  The other person did not see anything from me.  This is exactly the behavior I would expect.

Thinking back on this, I was trying DavMail and a few plug-ins offered for Thunderbird to see which worked best for communicating with an Exchange server.  One of the plug-ins I used was "ExQuilla for Microsoft Exchange".  I also tried "Provider for Microsoft Exchange", but could not figure out the proper server to set.  ExQuilla, though, I think has an option to automatically add meetings to my calendar.  I think ExQuilla may have saved the meeting to my calendar.  Then, when I deleted it, I was probably using the DavMail interface, since I couldn't get Provider for Microsoft Exchange to work.  Could it be that the DavMail interface thought I was the organizer because ExQuilla added it to my calendar in a different way?  Perhaps ExQuilla added it as if I were the organizer.

I do know that the meeting was automatically added to my calendar.  I did not accept it.

[Philipp Kewisch [:Fallen] [:📆][:🧩]]

I recently read that ExQuilla does not implement calendaring, so it may be a good idea to use the Provider for MS Exchange. It looks like you have quite a mix of add-ons and server settings that may be in conflict with each other.

The meeting may have been added to the calendar by the server too if that has not already been mentioned. Given you cannot reproduce I'm going to close this bug, feel free to comment if you are able to figure out more details.
