Sorry for the off-topic post, but I'm fishing. I'm one of the maintainers of vzic, a utility to convert IANA tzdata into iCalendar VTIMEZONE components. In the process of tweaking the tool to handle recent tzdata changes and to generate more correct/compact VTIMEZONEs in "pure" mode, I managed to break the generation of Outlook-compatible VTIMEZONEs. Try using git bisect or a similar process to figure out what change broke your Outlook-compatible VTIMEZONE generation, and or analyze the changes between your last known good sources and your current state.
I know which commit broke the code, I'm just trying to understand what Outlook (doesn't) wants to see in VTIMEZONE.
Does anyone know what parts of the iCalendar/VTIMEZONE spec that Outlook doesn't properly handle and/or know what the requirements are to be compatible with Outlook? Try throwing a hook into these ponds: https://docs.microsoft.com/openspecs/ https://blogs.msdn.microsoft.com/officeinteroperability/2015/09/22/exchange-... https://github.com/OfficeDev/Interop-MailSim
