Hello, I just spent about 2 hours online and on the phone with Microsoft support with no results. I'm hoping I fare better here!
From Outlook (version 1906) I subscribe to an internet calendar and all the appointments/events in this calendar are displayed as one hour later than the actual time. All my other calendars are fine. Just this one is displayed incorrectly.
Big clue: When the calendar is loading there are Send/Receive errors, that claim the TZID or time zone is unrecognized. Here is one of the errors:
Task 'Internet Calendar Subscriptions' reported error (0x0004001B) : 'The VEVENT, "Holiday Concert (#2)", defined near line 187, contains a property that references an undeclared time zone with a TZID of "America/Los_Angeles". Outlook found an approximate replacement, but note that some of your appointments may be off by an hour. Double-click to open this item.'
In fact, all of the appointments are off by an hour.
How do I get Outlook to recognize "America/Los_Angeles" as a valid time zone? I assume that's the root cause to this problem... yes?
Help!!! Thank you!!
FYI, in case you have access to this: my case number at Microsoft Support was 1478060928, and it is not resolved!
