I have had success using OAuth 2.0 with EWS when using admin permission. Now I am trying to set it up so that an individual user can log in and grant access for himself. So I start a browser with this URL:
https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=f3f92d23-29dd-4465-828e-35300884ef61&redirect_uri=https%3A%2F%2Flogin.microsoftonline.com%2Fcommon%2Foauth2%2Fnativeclient&response_type=code&scope=offline_access%20Calendars.ReadWrite.All%20Contacts.ReadWrite.All%20Mail.ReadWrite.All%20Tasks.ReadWrite%20User.ReadBasic.All
The browser allows me to log in to my test account, but then this error is returned:
error=invalid client
description=AADSTS650053 The application 'my app name' asked for scope 'Calendars.ReadWrite.All' that
doesn't exist on the resource '00000003-0000-0000-c000-000000000000'
In Azure, when looking at the API permissions for my application, I have 11 Exchange permissions, including both Application and Delegated permissions for Calendars.ReadWrite.All, in addition to all of the others that I requested.
What's going on here?
Because EWS is a legacy API it doesn't implement the more restrictive permission model that the Graph and Outlook REST API uses. The only permission that will work for Delegate access is EWS.AccessAsUser.All (Scope https://outlook.office.com/EWS.AccessAsUser.All). This gives full access to every folder in a Mailbox (and any mailboxes the user has been granted access to).It looks like you application registration already includes that permission so
https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=f3f92d23-29dd-4465-828e-35300884ef61&redirect_uri=https%3A%2F%2Flogin.microsoftonline.com%2Fcommon%2Foauth2%2Fnativeclient&response_type=code&scope=offline_access%20https%3A%2F%2Foutlook.office.com%2FEWS.AccessAsUser.All
should work

First, this is the document api for introducing the api permission, you can see Permission type with Delegated and Application.
The second, this is the section for introducing the request example, you can see that there are 2 types /me and /users/{id | userPrincipalName}.
The difference between the 2 kinds of api permission is that, using Delegated permission means we need to make users sign in first to generate the access token and call the api, while Application permission not. So when we use Delegated api permission, we can use api request like /me because the token contained the user information so graph api knows who is me and me is authorized to access this api. So we can also use users/user_principle_name_of_the_signed_in_user here. But it doesn't mean we can use another user principle name here, because other users aren't authorized in the access token.
How can we put any user of your tenant into the request and call the api successfully? We need to use Application permission here. When you add api permission, you may notice it and please add application api permission. Then we need to use client credential flow to generate access token with application permission. Then you may try yor failed request with the new token.
Application permission means you are calling the graph api on behalf the application, so it doesn't require users to sign in, but using delegated permission is much more safe since it will generate access token with limited scope(the api permission you defined in the token generating request), but client credential flow uses /.defalut as the scope, this means all the application api permission in the azure ad application will be added to the generated token, you can't control which application permission is allowed and which is not allowed in one token.
My question is, does Microsoft Graph work without User.Read scope ? I am not able to request the email profile openid permissions directly.
It throws AccessDenied error. So is User.Read pre requisite for email profile or openid ?
User.Read is just the delegated permission for getting the user profile using MS Graph Get User. If your app does not need to read the user profile you don't need this permission but in most cases you do because you app is acting on behalf of the user.
Does Microsoft Graph work without User.Read scope ?
No, but in most cases, you need the scope to read user profile and call /me endpoints.
You should check the api document to see if calling that api required User.Read permission.
For instance: I wanna call this api to list emails, and we can see that this api provides 2 kinds of permissions, one is for delegate, another is for application(this means client credential flow is supported). All the api permissions are listed here and we need to go to azure ad portal to add the api permission to your azure ad application which used to generate access token.
After generating the access token, you can user jwt decode tool to check if your access token contains correct scopes(for delegate permission) or roles(for application permission). Using a correct token to call the api will not lead to AccessDenied error. By the way, newly added permission may be deferrable to take effect.
I am building an app (HTTPS calls from LabVIEW) that will update my enterprise OneNote notebooks on Office 365 without the need for any user interaction. Hence I have opted for using the Client Credentials flow and granting Application permissions in Azure AD to my app (Read and write all OneNote notebooks) through Microsoft Graph.
I have referred to the instructions mentioned in the following pages:
https://msdn.microsoft.com/en-us/office/office365/howto/onenote-auth-appperms
https://developer.microsoft.com/en-us/graph/docs/concepts/permissions_reference
https://learn.microsoft.com/en-gb/azure/active-directory/develop/active-directory-v2-protocols-oauth-client-creds
https://developer.microsoft.com/en-us/graph/docs/concepts/auth_v2_service
https://developer.microsoft.com/en-us/graph/docs/concepts/onenote-create-page
I am able to get an access token from Microsoft Graph but once I try to use it to update my notebooks by making a POST call to the URL
https://graph.microsoft.com/v1.0/me/onenote/pages
I get the error:
"The OneDriveForBusiness for this user account cannot be retrieved." Code - 30108
However, I am fully able to access OneDriveForBusiness online using the same account which created the app and the tenant ID of which I used to grant permissions. Can someone please clarify if there are certain restrictions regarding the type of O365 and OneDriveForBusiness subscriptions that are necessary for my requirements? Which particular subscription or their combinations thereof should allow me to achieve the flow I need?
You cannot use /me with Client Credentials. /me is an alias for /users/{currentUserId but since you're using Client Credentials, there is a User in context for the API to map that alias to. You are effectively calling /v1.0/users/NULL/onenote/pages in this case.
You need to explicitly specify the User you want to access:
/v1.0/users/{userId or userPrincipalName}/onenote/pages
I am building an app where anybody in my organization can create planner task under a specified plan.
I am using Azure AD v2 endpoints for getting access token:
https://login.microsoftonline.com/common/oauth2/v2.0/authorize
https://login.microsoftonline.com/common/oauth2/v2.0/token
And using that access token to make POST request to following endpoint:
https://graph.microsoft.com/v1.0/planner/tasks
I have registered my App on: https://apps.dev.microsoft.com
And given necessary delegated and application permissions EDIT: ie Group.ReadWrite.All
(along with many others)
I am(having admin rights) able to create planner tasks using the API calls but no one else in the organization can. User gets this error message:
Need admin approval
Planner Task App
Planner Task App needs permission to access resources in your organization that
only an admin can grant. Please ask an admin to grant permission to this
app before you can use it.
I know that this user account has required permissions (because when using graph explorer api calls with same account, it works) so the problem lies in App permissions.
Any help is highly appreciated.
EDIT:
Bearer token for Admin (where app successfully creates a planner task):

Even after Admin has given consent to the app using (https://login.microsoftonline.com/common/adminconsent?client_id=my-app-id&state=12345&redirect_uri=https://localhost/myapp), non-admin user gets this:
As you have mentioned that you are adding planner task not just reading data, you have to grant permission Group.ReadWrite.All accordingly. Please check the permission and confirm about this.
ref: https://developer.microsoft.com/en-us/graph/docs/api-reference/beta/api/planner_post_tasks
In order to use Group.ReadWrite.All you need the consent of a tenant Admin. To obtain this you need to have an Admin on the tenant execute the Admin Consent process.
I have a walkthrough that might help you here:

I'm trying to use the Microsoft Graph API through the OAUTH2 Authentication however I'm struggling to work out how to use Delegated Permissions and not require a user to login.
I'm happy to authenticate the app with myself once, but this will be running on a daemon/service and won't be interacted with via a user. Because of this I can't use the way Microsoft describes Delegated Permissions as that uses /authorize first and then a call can be made to /token.
I know you can use secret keys for /token but it seems that only is using the Application Permissions and not Delegated - which is what I have access to.
Is there a way to authenticate using Delegated Permissions as if I was a user but without a user having to use a sign in page every time?
I needed to do something similar in a daemon app, but application permissions weren't available for the resource to which I needed access (Planner). I was able to accomplish it using the Resource Owner Password Credentials flow and supplying credentials for a service account instead of an actual user.
https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth-ropc
This isn't possible. The term "delegated" is very intentional here in that it means "the user has delegated their permissions to your application so you can operate on behalf of that user". Application permissions are not delegated because there is no user in context to delegate their access rights to you.
Authorization Code = Delegated Permission Scopes
Implicit Grants == Delegated Permission Scopes
Client Credential Grants == Delegated Permission Scopes
Much of the Microsoft Graph functionality works with both Application and Delegated scopes so in many cases you can still execute the same scenarios. There are some caveats such as using the shorthand /me which doesn't exist when there isn't a user authenticated (instead you need to use /users[{id}]). There are however some cases where there isn't an equivalent Application scope and these are regularly looked at in an effort to close the gap.
