The error is telling you that in the application registration you have created it doesn't list the resource eg outlook.office365.com your trying to access. So that tells you there is problem with the Application registration. Maybe try testing oAuth using the EWSEditor github.com/dseph/EwsEditor/releases

Thanks for the guidance Glen. I checked EWSEditor. I could successfully login using Oauth using default values provided in the application for the RedirectURL and Client app id. However when i provide the Client app id from the registration i have done in the portal (apps.dev.microsoft.com) is not working and throws the same error as before "AADSTS65005: Invalid resource."

I think i am missing something in registration & permissions, any pointers on how to register the application & required permissions to be granted will help.

With EWS you only have one permission that will work maybe post a screen shot of your registration.
