update outlook event changes originalStartTimeZone

(0) ShareShare
ReportReport
Posted on by 595

I am using "Update event (V4)" to add a category to each new event (in order to track to Dynamics 365).

For some reason the field

originalStartTimeZone

is changed, while this field is not retreived in the trigger ("When a new event is created (V3)") and it is not being used in the "Update event" step.

The change of this field causes some strange behaviour in outlook, where the details of the item show a different time and zone than the users' timezone... In the below example, I created a testappointment from 10:00 till 11:00 in my local time zime (UTC+1 = "Romance Standard Time"). After running the flow, the details of the appointment show the times in UTC (where it showed the right times and zone before the flow ran).

Any idea why this field changes or how to prevent it?
