Appointment ID is not Unique

[CM24]

Dear All,

      I'm trying to build a flow which uses the Outlook added/updated/deleted event as a trigger.

When an even is added, that bit runs fine.  It's when an event is deleted that I'm coming unstuck.  The problem is that when an event is deleted, the only information you have about that event is the ID.  In theory, this is fine - however, I have seen that when events are create or deleted they have the exact same ID. What I mean is that, if I create 50 new events, the ID field is identical for every single event.  I tested by having the ID written to a SharePoint Online List when an event is created.  Subject, start/end times are all different (as per the creation), but the ID field is always the same.

Now, from a "added" perspective, this isn't a problem.  But it means that when an event is deleted it is impossible for me to tell which event was removed - indeed, when "deleted" it shows (again) the same ID.

I am assuming that, for some reason, rather than giving me the ID of the event, it is instead showing me an identifier of the calendar.  But there is nothing else I can get

Help would be appreciated!

Thanks

Hi @CM24 ,

I made a test using the same trigger as yours, however, I cannot reproduce this issue, all event IDs are different.

Could you please share a screenshot of the IDs of your end?

Best regards,

Here is a list of ID's all from different appointment items:

And here is the flow that created that list:

Hi @CM24 ,

But all the ids are different:

This morning they do appear to be, as if to make me look universally stupid.

I am having a similar issue. I have events from Outlook overwriting existing items as if they share the same ID. What do I need to do to my flow to stop updates to events or even creation of new events from overwriting an different event already in the Sharepoint list?

I found that it wasn't the event ID that was the same, it was the calendar ID.

Once I corrected for that I could see that all event IDs are unique.

how did you correct for that? here are some sample events. I am finding that I have a good nummber that have the same ID, although the case may be different.
