Office 365 Outlook > When an event is modified (V3)

(0) ShareShare
ReportReport
Posted on by 425

I am attempting to set availability from Bookings Event; default 'Busy' to 'Tentative' however the trigger event fires many times instead of what I presumed would be a single event.

 

New Event fires 1 time

Modified Event fire multiple times

Trigger Condition set as

 

@equals(triggerBody()?['organizer'],'ORGANIZER EMAIL ADDRESS HERE')

 

 

Should I be using the other parameters to get the specific modified event, if so, how do I implement?

    Hi @ChrisMendoza ,

     

    Please take a try with trigger condition in your second flow as below:

    @and(greater(triggerBody()?['createdDateTime'],addMinutes(utcNow(),-5)),equals(triggerBody()?['organizer'],'ORGANIZER EMAIL ADDRESS HERE'))

     

    The expression would check if the event is created in 5 minutes, if yes, don't trigger the flow when an event is updated.

     

    Best Regards,

    Alice

    @v-alzhan-msft-

    Thank you for your suggestion however, this would not meet my goal as the event could change anytime between ['createdDateTime'] and ['start'] not just within 5 minutes of creation.

    Why would the trigger event 'When an event is modified (V3)' fire repetitively in a loop? It seems like the trigger does not "know" which event was modified; that seems odd, right?

    Currently testing 3 existing events. With the above Flows, specifically 'When an event is modified (V3)', the trigger fires over all three events in what seems to be an infinite loop.

     

    I decided to try ['Response Requested'] = false. Now the trigger fires over the modified event in what seems to be an infinite loop. So that's some progress.

    Hi @ChrisMendoza ,

     

    My solution would be the easiest way for your issue, if the 5 minute couldn't meet the requirement, you could consider 2 minutes.

    Again, thank you for your suggestion. A time constraint will not be sufficient for my need.
