Unfortunately some of my appointments (synced from Microsoft Exchange server) are shown in the wrong time zone although the correct start and end time is also visible in next cloud. in Microsoft outlook the appointment is shown in the correct time zone.
I attach a screen shot from an entry that is shown in the calendar at 19.30 to 20.30 but actually it was created for 13.30 to 14.30.
I also paste the content of ics files exported from outlook and from nextcloud. maybe that helps to understand the problem and find a solution.
Thanks for your help and let me know in case you need more details.
Cheers, Marvin
