Error opening an activity in outlook - event created via API

Mirko Sarzo 26

Good morning,

I encounter an anomaly when opening an activity created via microsoft graph API.

To create this activity I used the function made available by Microsoft's DLL.

GraphClient.Me.Events.Request.AddAsync (Event)

I noticed that through OWA I can open the activity and edit it without any problems.

Thanks to those who can help me.

the message is not meaningful. if you restart it doesn't change anything.

Just a reminder that for most messageboxes in Windows, you can simply hit Ctrl-C or Ctrl-Insert to copy the message as text and paste it here. This will allow helpers to have easier time "translate" your message to find out what the problem is.

Also as of current time, this forum have very limited support for non-English questions. So you'll have better chance to get someone try to resolve your problem by translating the error message in English yourself.

Can you capture the error response returned by the function call?

It's usually in form of the following, and should give you better detail on what's the reason for failing.

{ "error": { "code": "invalidRange", "message": "Uploaded fragment overlaps with existing data.", "innerError": { "requestId": "request-id", "date": "date-time" } } }

When I open an event through outlook it gives me an error, not when I send the event via API.

Okay so it could be data corruption for that event where Outlook is expected something that OWA doesn't care.

Maybe you can try sending example event in here (of course modify the dates to a future date and set recipients to yourself) and see if it can create a event that can be opened without problem in Outlook?

Thanks for the support, I found my error.
I sent ReminderMinutesBeforeStart = -1 to the API.
API accepted value, OWA showed event but outlook desktop version didn't work.

Just to isolate the issue you can try make the call in POSTMAN/Microsoft Graph explorer and see if you can repro the issue or not.

Also you need to check whether you can able to open the mailbox in Outlook UI or OWA without any problem as well

If you can repro the issue then share the Graph response that you receive (requestid, timestamp, error info).
