Calendar: Rescheduling of meetings invited from Outlook not working

[Galdan]

Hi everyone,

I am experiencing an issue where updates to meetings sent from Outlook to Nextcloud do not reflect in the Nextcloud calendar entry.

Steps to reproduce:

1. Create a meeting in an external Outlook/Exchange account and invite a Nextcloud email address (e.g., Sunday at 13:00).
2. Accept the meeting in Nextcloud via the Mail App by clicking the “Accept” button.
3. A message appears in the Mail App stating, “You accepted this invitation.”
4. The meeting is successfully scheduled for Sunday at 13:00 in the Nextcloud Calendar App.
5. Update the meeting time in the external Outlook/Exchange account to, for example, Saturday at 14:00.
6. An email arrives in the Nextcloud Mail App, but it does not provide an “Accept Invite” button. Instead, it immediately states, “You accepted this invitation.”
7. The meeting remains scheduled for Sunday at 13:00 in the Nextcloud Calendar App.

Is this a configuration issue on my part, or is it a known problem?

Thank you very much for your support.

Best regards,
Galdan

It seems to be an issue with the mail app, there is already a report on the bug tracker:
