I recently tried to make a Flow which would automatically update an outlook event whenever a ToDo was updated. In this process I must have misidentified the event ID because it changed ALL of my events in outlook (even events in which I did not create) to the same time/data. I have no way to go back in outlook and edit these events, as I am not the organizer.
How can I reverse what Flow did, or at the very least get into these events in my calendar to adjust the times back to what they’re supposed to be?
If you did a Get events action in your flow prior to updating the events, then the output of that action will be basically a backup of how your calendar was, which you can find in the run history. You could copy the JSON output of that action and paste it into a Compose in a new flow and then run an Apply to each on that to update the events with the start and end time from that data.
