I am going through with an issue while merging MS Graph java SDK in my existing meeting screen project for 'Auth Flow provider'.

[jagriti22]

As for Client Credential provider Flow , Azure Application level 'Calendar.readWrite' permission is required which is not permissible in my company because I will get permissions of read write calendar of other employees. Is there another way from which I can write auth flow with delegated permissions and use these fields (isonlineMeeting,onlineMeetingProvider) to create MS Teams Meeting??

I am using MS Graph Event Class/APIs, MS Graph Java SDK.

This is my code:

Do you need to create these meetings in the context of a user? If so, you'll want to use the UsernamePasswordProvider although this is not the recommended approach. Better yet, use MSAL to acquire token for your application running in your user's context.

If you need to create meetings directly on someone else's calendar, you will need a confidential client, and that will mean getting tenant admin sign off on your app.
