Hi @fei han ,
Please kindly understand that here we mainly focus on general issues about Outlook desktop client and know little about scheme and developer.
I tried some search and found some information which might be useful. In this similar thread, the code below @JakeTesler mentioned could work for some other users:
ms-outlook://events/new?title=MY%20MEETING&start=2019-01-29T13:00:00&end=2019-01-29T14:00:00&location=LOCATION&attendees=******@email.com
For more information, please check: Programmatically add calendar event to Outlook on iOS or Android. (Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.)
Hope this can be helpful.
