I have added a Web Application in the Microsoft Application Registration Portal. I can view this app in old azure portal. When I try to configure this app as multi tenant and set the Sign-on URL and the App ID URI values, an error pops up saying one of the values is invalid and the save fails. I can connect to this application using OAUTH and get the required refresh and access tokens. Using these tokens in the graph API I can get mails,contacts and calendar events from my office 365 account. But this happens only for a single tenant. I need to able to do this for multiple tenants and so I want to set this app as multi-tenant. If I create the application in Azure AD itself then I am able to set all the values but I cannot connect to this app using OAUTH as the authentication fails with error message saying
error=unauthorized_client&error_description=AADSTS70001%3a+Application+%2791470123-7e7e-4139-9922-ac95b0a6b383%27+is+not+supported+for+this+API+version.
.I went through a few links like here , here and here but until now I haven't been able to find a solution. I am re-posting this as suggested here. Can anyone suggest what I must do to get through this ?
