A couple of our users complained that some of the recepients of the appointments they made in teams received them with a time that was two hours off. After extensive testing, I did find a problem, which I have been unable to fix.
All ics files which are send have a TZID:W. Europe Standard Time, which the external recipients have no problem with, but if they move the appointment in the webmail owa, this changes automatically to UTC. I don't see any option to stop exchange from changing the timezone. If they move an appointment in Outlook or Teams, the timezone stays as Western European Standard Time. Is there any way to keep Exchange from making this change?
