Getting an objectId from AAD by email - reactjs

I am new to Azure Active Directory. I have a demand for following functionality: I need to get an objectId of the user who is not invited into my resource group/subscription. Just some Azure user providing an e-mail. Is there any kind of API to do this? I have tried to look into Graph API, but didn't notice a suitable method.
Technology stack is ReactJS. Currently, using ADAL, but it is suitable for authorization and I didn't find a functionality to get information about non-curent users.
Thanks in advance!

You can obtain user's details from Graph API using id or userPrincipalName (which is an email address).
From Microsoft Graph API reference:
GET /users/{id | userPrincipalName}

Microsoft Graph external user access

I have an issue with accessing user data with microsoft graph api.
Context : I have a web app with a calendar inside for my users. I would like to give the user the possibility to synchronise this calendar with their microsoft calendar. I did the same thing with google calendars and it works well.
Problem : I registered an app on azure and setup my code with the correct access to login and get a token from the graph api.
It kinda works but i can only log in with the address i used to create my app on azure.
So lets say my admin address on azure is test#azure.com , then i can log in and access the data i want . But if i try with another address like for example test#customer.com, then it fails and display this message :
I keep looking for a way but the Microsoft graph documentation doesn't seem to talk about this problem.
I tried to add the account as an external user, like the message says (and maybe i did it wrong i'm not really sure of this part) but then i can log in but the data i can access doesn't match the data on the account i tried with, as if adding the user as an external user created a "new" user in my organisation.
What I want : I would like to be able to access the data of any user that try to log in with a microsoft email (if they accept the permissions of course).
It's my first time using the graph api so maybe i'm missing something simple...
Thanks
Based on the So thread reference:
When a user authenticates against your tenant, you only have access to the data controlled by your tenant. In other words, if test1#outlook.com authenticates against yourtenant.onmicrosoft.com tenant, you don't gain access to their outlook.com email.
Reason you're able to see the outlook.com email from Graph Explorer is that Graph Explorer is authenticating against their outlook.com account.
In other way, Graph Explorer is authenticating test1#outlook.com against the outlook.com tenant, not yourtenant.onmicrosoft.com.
When a user authenticates against a given tenant, that token only provides access to data within that single tenant. Microsoft Graph does not allow you to cross tenant boundaries.
Thanks Hong for the comment, you may also set your app registration to "multitenant + personal accounts"

Get preferred_username with microsoft graph API

I'm trying to get the preferred username of a user via the Graph API for Microsoft Office / Azure
If a user logs in via an enterprise application with an id_token I get the preferred_username claim.
This has the user's actual email address.
If I try to look up the user separately by ID, I can't find any way to get that username.
Seems related to Sign-in to Azure Active Directory using email as an alternate login ID (preview).
The user in question is using a GitHub linked account, it likely has an ugly UPN that I would prefer not to be seen anywhere. Instead I would like to use their preferred_username.
Example "ugly" UPN":
***_gmail.com#EXT##***gmail.onmicrosoft.com
To my knowledge, the preferred_username value isn't exposed by Graph in either v1.0 or Beta.
One potential workaround is to use the otherMails property. This is an array, so this may contain multiple entries for a given user. That said, any otherMails entry is likely to be less 'ugly'.

Reliably identifying a Teams guest user

I have a Microsoft Teams tab app and I'm using SSO for authentication. My users are both native and guests. My requirement is to show different screens depending on the type of incoming user (native/guest), so I have to identify the user type first. To ensure security, I first obtain the id token for the incoming user and then validate it first before identifying the user type. Is there any reliable way to identify the incoming user type with just the id token? I don't trust the info in tab context.
If you don't want to use Microsoft Graph API, you could add all the guest user into a security Group and include Groups claim in your token as instructed here. You just need to modify the "groupMembershipClaims" field in application manifest:
"groupMembershipClaims": "SecurityGroup"
Then the ID token will contain the Ids of the groups that the use belongs to like below :
{
"groups": ["1ce9c55a-9826-4e32-871c-a8488144bb32"]
}
You can also Add app roles in your application and receive them in the token.
You can use microsoft graph api(beta) get user.
https://graph.microsoft.com/v1.0/users/{id | userPrincipalName}
If the id token contains objectId of the user, just put the objectId as the parameter of this api. In the response, we can find an attribute userType. The value of this attribute could be Member or Guest.
If the id token doesn't contain objectId of the user, just contains email. We can also put it as the parameter in the graph api, but if the email is a guest user, the api will not get response data. So I asked you if it contains objectId in the comments.
By the way, the attribute userType just exists in the beta version of microsoft graph api but not exist in the v1.0 version microsoft graph api. So if you're not comfortable with beta version, I suggest to use Azure AD graph api(get user) instead of Microsoft graph api.
Hope it helps~

Get object identifier of Microsoft account from shared tenant (9188040d-6c67-4c5b-b112-36a304b66dad)

Is there a way to get value of "objectIdentifier" claim for Microsoft account?
Case: I have an app with one form field, email (need's to be Microsoft account). When this email is entered, server (back end) need's to find out value of object identifier (user ID) in common tenant for all Microsoft accounts (section "tid").
Normally, if this was normal tenant in Azure Active Directory I would create Azure AD app and generated client secret for accessing Graph API, directory endpoint. Unfortunately, this is "special" tenant and I don't know is there any API I can call (as application) to get id of user (best option would be GetUserIdByEmail(email)).
I understand this is weird case but life is hard :)
Asking user to login and then retrieving value from token is not an option!
There is no API that I'm aware of where you could query for MS personal accounts' info without logging a user in.
If you think about it, it would be quite an easy source of building a user list for attacks :)
You will need to log them in to get their id, I don't think you can know it in advance.

Unable to get user company information on microsoft graph API

I'm having a problem with Microsoft Graph API... Currently I have a web application that has an openid integration with Microsoft/Azure using the common v2 endpoint.
We are trying to get the signed in user company name and job information. The official docs say that we need to make a request to the MS Graph API.
We are testing it on Microft Graph Explorer but it doesn't seem to work.
We've selected the 'User.Read' as a permission in our app, then tried these endpoints:
https://graph.microsoft.com/v1.0/me/
https://graph.microsoft.com/v1.0/me?$select=companyName,jobTitle
https://graph.microsoft.com/v1.0/users/?$select=companyName,jobTitle
In MS offical doc (https://developer.microsoft.com/en-us/graph/docs/concepts/permissions_reference) on User/Remarks sections, it clearly says that
"On reads, only a limited number of properties are returned by default. To read properties that are not in the default set, use $select"
Is this doc outdated?
I've tried to reach MS support for developers, but they answered saying that I should ask this on Stack Overflow...
So probably there are no official support for developers?
Is it really possible to get the company name and job title from a MS account?
Thanks in advance!
edit. Update question with MS graph explorer screenshots
edit.2. Update screenshot with proper encoding.
Also, it's a MS account not an Azure account, since our web app accepts both of them on the common v2 endpoint.
Update
My goal was trying to get the Work Info section from a MSA account.
The documentation is correct, by default we only return a subset of user properties:
id
userPrincipalName
displayName
givenName
surname
jobTitle
mail
mobilePhone
businessPhones
officeLocation
preferredLanguage
If you want a different set of properties, you can request them using the $select query parameter. The queries you provided in your question should work fine. For example, when I execute https://graph.microsoft.com/v1.0/me?$select=companyName in Graph Explorer (after logging in with my credentials) I get the following:
{
"#odata.context": "https://graph.microsoft.com/v1.0/$metadata#users(companyName)/$entity",
"companyName": "MICROSOFT"
}
Update Regarding MSA
When using Microsoft Graph against a Microsoft Account (MSA) there are several differences in what properties get surfaced. As an MSA is by definition a personal/individual account, organizational properties such as Job Title and Office Location are simply not applicable.
