I am trying to fetch the rooms data from another organization. For that, I have successfully generated the JWT token by giving almost all permissions by A organization for the particular user and also created the Login URL for the consent with all permissions. And accepted permissions for the B organization.
But when I try to fetch the rooms API from the A organization user it throws, access denied.
I'm not sure what you actually mean by "organization" but if you are referring to a DocuSign account, then this is not allowed. You cannot use one account context to get information from another account. You would have to change the authorization, permission, and consent to be for the same account from which you're trying to get information.

In my application in Azure Active Directory I have added one of the Admin's consent required permission to the Graph API, let say Group.Read.All. I've clicked Grant Admin Consent for .... If I hit /authorize endpoint as a User with the query parameter prompt=consent, I'll get the view that I need admin approval. If I hit the endpoint without any prompt parameter, everything works fine - I'm able to get a token with a proper scope. In the documentation I've read that prompt parameter determines only the visibility of the consent. Why it works like that?
Regarding prompt=consent, OpenID Connect says:
The Authorization Server SHOULD prompt the End-User for consent before returning information to the Client. If it cannot obtain consent, it MUST return an error, typically consent_required.
In the Microsoft Identity platform, this means that the end user will be required to provide consent, even if consent has been granted previously by the user or (in the case of work or school accounts, by an administrator on behalf of the user).
If the user is not authorized to consent to the requested permissions (e.g. because user consent is disabled or restricted), using prompt=consent will always result in a hard block for the user.
In most cases, using prompt=consent is not the best approach. There are typically three scenarios prompt=consent is considered:
You've changed the required permissions. The required permissions have changed (e.g. permissions have been added or removed), and the user needs to consent to the new set of permissions.
You want to inform the user. The app developer wishes to ensure the user is informed of which permissions the app will be authorized to exercise (even if an administrator has already consented on behalf of the user in question).
You require consent from the user themselves, not an admin. The app developer wishes to ensure the end-user themselves provides consent, independent of what an administrator may have authorized previously.
If you've changed which permissions are required
When the requested permissions are defined dynamically
On the v2.0 endpoint, the scope parameter can be used to dynamically request a list of delegated permissions. For example, to request the read and export delegated permissions of the API identified by https://api.example.com:
scope=openid https://api.example.com/read
Azure AD will ensure that all the requested permissions have been granted, and attempt to prompt for consent for any permissions which have not yet been granted (and only for those). If the requested permissions have all been granted, the issued token will include all granted permissions (even if they were not specifically requested).
Generally speaking, when making use of the incremental consent capability of the v2.0 endpoint, prompt=consent should not be used. Azure AD will take care of prompting for incremental consent if needed.
When the requested permissions are defined statically
An app can also identify only the resource (i.e. the API) for which it is requesting an access token, the specific permissions being defined statically for the app. Using the v2.0 endpoint, this is done in the scope parameter, making use of the special .default permission value:
scope=openid https://api.example.com/.default
In the v1.0 endpoint, this was achieved using the resource parameter:
resource=https://api.example.com
The list of required permissions is configured in a static list on the app registration. In the Azure portal, this list is under Configured permissions in Azure AD > App registrations > API permissions. In the unerlying Application entity in Microsoft Graph (and in the app manifest), this is stoerd in the requiredResourceAccess property.
On receiving a request of this type (on either the v1 or v2 endpoint), Azure AD will check which permissions have been granted for the requested resource:
If no delegated permissions have been granted for the requested resource OR if prompt=consent is used, Azure AD will attempt to prompt for all the required permissions from the statically-defined list. This will include permissions for other APIs, if any are configured.
If any delegated permission has been granted for the requested resource, Azure AD will issue the token with all granted permissions. The scopes parameter of the response will include the list of permissions included in the access token.
Applications relying on statically-defined required permissions (i.e. /.default on v2 or resource on v1) should not use prompt=consent for every sign-in request. Instead, the application should:
Perform a sign in without prompt=consent.
Check the scope parameter of the response:
If the desired permissions are listed, no further action is necessary.
If not (e.g. if a new permission was added to the list of required permissions after the user initially consented to the app), only then should the user be sent back again, this time with prompt=consent.
This strategy ensures that users can sign in to an app when an administrator has consented on their behalf (e.g. because they aren't authorized to consent on their own), and only forces the consent prompt (or an escalation to an admin to consent on their behalf) when a new permission has been configured.
If you want to inform the user
Using prompt=consent is not a good approach if the goal is to only inform the user of which permissions the application has been authorized to exercise (either by the user previously, or by an administrator on the user's behalf).
Instead, an application can use the scope parameter of the token response to construct the desired interrupt experience (e.g. after the user has been redirected back to the app and the token has been retrieved, but before continuing), informing the user of which permissions it has been granted.
If you require consent by the user, not an admin
There may exist very specific cases when an application requires user consent for the requested permissions, and wishes to not accept consent granted on behalf of the user by an administrator.
In this case, using prompt=consent in all sign-ins could be used, but there are important caveats to consider:
In many organizations, user consent is disabled or restricted. If users are not authorized to consent to the permissions configured for your app, they will not be able to use your application.
The user will be prompted for consent every single sign-in, even if the user themselves already previously granted consent.
Since this is a query parameter, a knowledgeable user could very easily intercept the request before it is made, and remove prompt=consent (and if consent was already previously granted, they will not be prompted for consent).
In this case, it may be better the app to implement a separate consent-granting experience after the user has signed in (similar to the "inform" scenario described earlier), separating the app's additional consent requirements from the consent experience provided by the Microsoft identity platform.
prompt=consent triggers the OAuth consent dialog after the user signs in, asking the user to grant permissions to the app.
Individuals accessing an app that requires at least one permission that is outside their scope of authority.
Admins will see the same prompt show the permission and will see an additional control on the traditional consent prompt that will allow them consent on behalf of the entire tenant.
Users will be blocked from granting consent to the application, and they will be told to ask their admin for access to the app.

Proper apps permissions from azure AD to grant access on Microsoft Graph where we can extract users emails information like To, From, Cc, Bcc, Subject.
Tried to grant all access but still encountering an access denied error.
None
Expected result will show users emails information like To, From, Cc, Bcc, Subject.
I suppose you want to use the Microsoft Graph - Get message, it returns the message object which has the properties you want.
If you want to call the Microsoft Graph without a user, you need the Application permission Mail.Read. You just need to create an Azure AD Application and grant the permission for it, the application permission Mail.Read need admin consent, so don't forget to grant admin consent, about consent an application, see this link. For more details about all the steps, see Get access without a user.
If you want to call the Microsoft Graph on behalf of a user, you need the Delegated permission Mail.Read, more details see Get access on behalf of a user.
Besides, if you want to get a message in another user's mail folder, please note the information as below, see Get message.
I want to send emails using Microsoft Graphs API from a backend service developed in node.js, that has no interactions with the user.
If I understand it correctly from this paragraph, if I use the Get access without user procedure, the administrator will have to give me some rights and then I will have those rights on every user account in the organization. This is not my goal, I only want to have those rights for one specific account, for which I have the login and password.
Is there a way to log in with an office365 account without user interaction?
Thanks :)
No. You need to have the user authenticate in order to obtain the initial access token and refresh token (to refresh your permission to access the account).
I need to write a backend app to read & write one company emailbox.
I have registered Active Directory Application and granted Delegated permissions (read and write to user mailbox).
Question is how to get the token needed for authenticate the graph api calls(for example ListMessages).
From the document I coundn't find any working example for backend app aquiring token and make api calls.
There are two endpoint versions:
Azure AD and Azure AD v2.0 endpoints;
And two authentication method:
1. Get access on behalf of a user
https://developer.microsoft.com/en-us/graph/docs/concepts/auth_v2_user
2. Get access without a user
https://developer.microsoft.com/en-us/graph/docs/concepts/auth_v2_service
What shoud I use ? Really confused.
Thanks all.
According to your description, I assume you want to get an access token without user login page.
Based on my test, we can get an access token that run as a background services or daemons.
It requires administrator to grant the access permission once, then user will not see login popup window anymore.
For more detail, we can refer to this official document.
Sounds like you are looking for Resource Owner Password Credentials grant flow.
However its usage is not recommended.
It does not work in these scenarios:
User has MFA
User password has expired
User is federated (MS account/Google/on-prem AD)
The only scenario that I can think of where this flow is okay is integration tests of APIs where you need to test scenarios where you call your API on behalf of a user.
Here is a better way to do what you want:
Require an application permission to access user emails and have the admin grant it. Now you can use client credentials grant flow to get a token anytime you need one.
Use delegated permissions, have the user sign in once with Authorization Code grant flow. Then exchange the code for an access token and a refresh token. Store at least the refresh token somewhere secure. Use refresh token whenever you need a new token.
The first approach is more reliable but requires broader permissions.
The second has tighter security (only users who have authorized access can have their email read), but has slightly less reliability.
Refresh tokens can be invalidated, in which case you'll need the user to login again.
In my third-party web application of Office 365, I want to have access to the contacts, events and emails of all the users from the organizations who installed my app.
The thing is I don't want that all these users have to grant me access, I just want one admin of the org to grant access for my app and then be able to retrieve the data I need for all the users.
To test for one organization, I logged in as the admin and proceed to the Oauth2 authentication to retrieve the access token and in the first request (the GET one to retrieve an authorization code) i add the parameter prompt=admin_consent.
With this access token, I can access the data (emails, contact, event) of the admin
for instance for the contacts
uri: https://outlook.office365.com/ews/odata/Users(adminemail)/Contacts
but not the data of the other users of this org with this uri
uri: https://outlook.office365.com/ews/odata/Users(useremail)/Contacts
The only thing I can do is retrieve an access token for each user but it supposed that each user has to authorize the access to the app but it's very cumbersome.
So, i don't see what enables the parameter prompt=admin_consent and how to use it. Does anybody know what it does?
And my question is: how can I do to access the data of all the users of one organization when the access has been granted by one admin?
Thank you!
Thanks for your question! The scenario you are interested in (an app accessing data of all users of an organization once an admin grants access to the list) is not yet supported but is prioritized high on our list of features to add.
[UPDATE] Support for app accessing data of all users in a tenant is supported for Office 365 Mail, Calendar and Contact REST APIs. Please see Building Daemon or Service Apps with Office 365 Mail, Calendar, and Contacts APIs (OAuth2 client credential flow) for more info.
The scenario prompt=admin_consent is intended for, is different from your scenario. Admin consent simply means that the admin allows this app in the organization without the individual user to see the consent screen after signing on to the app. This special "I as the admin provide consent for this app on behalf of all my users" is triggered by the "prompt=admin_consent" parameter that is passed in during the authorize request. However, this doesn't allow the app to get AccessTokens for any user. Each user still has to get the app, sign in, and the app will hit the authorize endpoint and get a Refresh/AccessToken for the signed in user.
Please let me know if you have any questions or need more info.
Thanks,
Venkat
