I was not able to reproduce the error. What would be helpful though is to catch an F12 Network Trace when trying to edit the event in outlook.office365.com and you see the error. Then you can private message it to me!

  Can you be more specific on how to catch an F12 network trace error. When I press F12 I get a window with lots of web programming stuff. But I don't know how to find the error this way. BTW, I'm using Chrome browser.

    This is a regression that we have recently fixed. The fix is currently being deployed and should reach 100% saturation by this Friday.
    
    It is indeed related to custom time zones set by third party clients.
    If the fix has not reached your mailbox yet, some possible workarounds are:
    a. Change the event's time zone to some other value and back before saving, or
    b. Use another Outlook client to do the update. Subsequent edits should be possible in OWA
    
    I apologize for the inconvenience

  Similar issue - created event on phone and can't edit on outlook office 365. Looks like a problem with custom time zones being set somehow. That is the only difference I see in requests that work and ones that don't.
  
  Here is a request that successfully changed the time of an appointment created via 0365 online:
  
  action=UpdateCalendarEvent&n=88&app=Calendar
  {"__type":"UpdateCalendarEventJsonRequest:#Exchange",
  "Header":{"__type":"JsonRequestHeaders:#Exchange","RequestServerVersion":"V2018_01_08","TimeZoneContext":{"__type":"TimeZoneContext:#Exchange","TimeZoneDefinition":{"__type":"TimeZoneDefinitionType:#Exchange","Id":"Eastern Standard Time"}}},
  "Body":{"__type":"UpdateCalendarEventRequest:#Exchange",
  "EventId":{"__type":"ItemId:#Exchange","Id":"redacted"},"ItemChange":{"__type":"ItemChange:#Exchange","Updates":[{"__type":"SetItemField:#Exchange","Path":{"__type":"PropertyUri:#Exchange","FieldURI":"Start"},"Item":{"__type":"CalendarItem:#Exchange","Start":"2019-06-07T09:00:00.000"}},{"__type":"SetItemField:#Exchange","Path":{"__type":"PropertyUri:#Exchange","FieldURI":"StartTimeZoneId"},"Item":{"__type":"CalendarItem:#Exchange","StartTimeZoneId":"Eastern Standard Time"}},{"__type":"SetItemField:#Exchange","Path":{"__type":"PropertyUri:#Exchange","FieldURI":"End"},"Item":{"__type":"CalendarItem:#Exchange","End":"2019-06-07T09:30:00.000"}},{"__type":"SetItemField:#Exchange","Path":{"__type":"PropertyUri:#Exchange","FieldURI":"EndTimeZoneId"},"Item":{"__type":"CalendarItem:#Exchange","EndTimeZoneId":"Eastern Standard Time"}}],"ItemId":{"__type":"ItemId:#Exchange","Id":"redacted"}},"EventScope":0}}
  
  Here is a request that failed to change the time of an event created on my iphone via the ios calendar when I tried to change it in O365:
  
  action=UpdateCalendarEvent&n=97&app=Calendar
  {"__type":"UpdateCalendarEventJsonRequest:#Exchange",
  "Header":{"__type":"JsonRequestHeaders:#Exchange","RequestServerVersion":"V2018_01_08","TimeZoneContext":{"__type":"TimeZoneContext:#Exchange","TimeZoneDefinition":{"__type":"TimeZoneDefinitionType:#Exchange","Id":"tzone://Microsoft/Custom"}}},
