"Party crashing" message shown when accepting invitation and no reply sent

[minderdl]

Describe the problem and steps to reproduce it:

Setup: Thunderbird 91.5.0 and gdata provider 91.0.2 with "Enable email scheduling" turned on
Receiving invitation to my private mail address, which is not the googlemail address. This address is also set in the calendar property dialog in the "e-mail" dropdown.

What happened?

When clicking accept in the invitation a dialog is shown: "Party crashing? You are not on the guest list yet". In the "respond as" dropdown I choose the same, private mail address.

The appointment is added to the calendar (and synchronized with google), but no reply mail is sent - neither by Thunderbird nor by google. Moreover, both the organizer and the participant are changed to the googlemail address, all other participants are removed.

What did you expect to happen?

Organizer and participant list shall not be removed. A proper reply mail shall be sent by Thunderbird showing the acceptance.

Anything else we should know?

Nothing interesting happens in the log file IMO. First 5 lines happen when I click on the received invitation mail, the rest when I've completed the "party crashing" dialog.

With 91.0.2, the scheduling prefs are not actually saved. Can you try again with 91.0.4?

I'm using 91.5.0. I receive the party crashing message each time I try to respond to an invitation. Is there a setting to tell Thunderbird to reply using the address from the invitation?

I have this same issue / confusion. I keep getting these "Party Crashing" messages and I don't know how to fix the problem. Consequently, I expect these events to be in my Google Calender (it used to work) but now they don't show up anymore. (I can only see them inside the Tbird calendar). Sad.

Sorry this is an issue folks, invitations in Thunderbird are unfortunately a bit messy. With the architecture we have and what the provider can do today, I'd strongly advise to only accept invitations into Google Calendar using the primary calendar (the one with your name on it), and for invitations received for the email address associated with that calendar.

There is an option in the Google Calendar web settings to auto accept invites, this is probably the best workaround for now.

I'm not sure I can reasonably support other use cases to the above, I've rather been trying to make it impossible to otherwise accept invitations. There isn't a lot I can do in the provider to fix this. I'm going to leave this open for a while in case someone has an idea, but I unfortunately can't promise a fix any time soon.

Would it be possible to explain a bit what is happening, i.e. the trigger and the consequence? Is TB just not parsing the invitee list correctly? Is it then adding my name to the list when go past the warning?

I don't use Google but recently switched from using my local calendar as primary to using one located on a private server. The people who send me invitations mostly use Teams, and now I am getting this Party crashing warning every time.

[adriesse]

Perhaps this has to do with the calendar not correctly distinguishing between my account name on the mail server, and my email address that uses my own domain name. When I send an invitation now, it show up at the recipient coming from the former.

October 2023 and version 115.4.1 this still seems to be an issue

[gmkayaker]

I have my own domain forwarded to a gmail account. I am accepting the invitations into another google calendar owned by the gmail account (but not the calendar associated with the user name). As far as I can tell, I get the party crashing message regardless of whether I accept it into the main calendar or the subordinate calendar. It would be good to have a plain user language explanation of what is causing this problem so that we can take the appropriate actions. And what happens behind the scene. I have tried setting the e-mail address associated with this calendar to the incoming invitation and I still get asked to change the e-mail address I'm responding from. TB 115.10.01
