I would like to integrate the Planner feature of Teams into a custom C++/Qt application. I'm not familiar with writing bindings C# <-> C++, so I'm exploring the possibility to use an external process that communicates with Microsoft Graph. I'm going to build this process with the C# Graph SDK.

Question: Is it possibile to avoid authentication every time I launch the process? Since I'm going to spawn this process many times (ie. each time I need to access Graph info) I want to avoid authenticating each time.

I've tried using Microsoft authentication extensions for .NET, and while the sample application seems to be working fine, I can't figure out how to connect it with the GraphServiceClient class.

I am using this library (Microsoft Graph .NET client library) in my project to retrieve emails from my mailbox. However, when I try to filter messages from my mailbox by createdDateTime or body, I get a "Bad Request" error. Here are my requests:

I understand that based on the documentation here that with the C# Graph SDK library I can continue requesting the next page of results until NextPageRequest == null, but I was wondering if I could save the NextLink I get back and if I encounter an error, the next time this is executed, I could resume at the place I was at using the NextLink (using the C# SDK library).

I haven't been able to find anything in the documentation around this. Is this perhaps something I could do with the RequestBuilder?

Im trying to set label using MIP SDK. However while executing AddEngineAsync, I am getting access denied error. I am able to get access token from AAD APP. Any help would be great.

Code:

I'm currently doing a small poc on Microsoft Graph API by following the tutorial here but facing an issue where AuthorizationCodeProvider could not be found. I've installed all the necessary packages and all. What am I missing?

I want to extend an existing migration tool to set sensitivity labels on files before they get imported into Sharepoint Online. I have found the Microsoft Information Protection SDK, which seems to provide the necessary API.

To get familiar with the API, I downloaded and ran the ServicePrincipalAuth example application (see https://docs.microsoft.com/en-us/samples/azure-samples/mipsdk-dotnet-file-serviceprincipalauth/mipsdk-dotnet-file-serviceprincipalauth/). But although I have followed the steps exactly, I always get an AccessDeniedException with message "The service didn't accept the auth token" in the CreateFileEngine method at the line

I'm creating an expo sender application which is web based, but I have a problem compiling the project. It keeps me saying

"Type or namespace definition, or end-of-file expected"

My code looks like this and I've got it from here

I get the following error when Updating a user using Microsoft Graph Beta. Permissions should not be an issue as I'm using the following permissions: user.readwrite.all, directory.readwrite.all. Also, HireDate is of type DateTimeOffSet that I'm getting by converting local DateTime to DateTimeOffSet. So, that should not be an issue either. Question: What could be the cause of the error and how can it be fixed?

I actually have two questions which may possibly be related:

Question 1: Why does user personal email address appear in Azure portal as User Principal Name?

Question 2: How do I look up a user by their personal email address?

The email address I will be looking for is the one used as a sign in name so I expect that it should appear in a property like signInNames as is mentioned below.

Steps to reproduce:

Log into Azure portal, Look at a random user and observe their User Principal Name. Note it appears in the format of a personal email address (joe@somedomain.com). Copy the users Object ID.

In code, create a new GraphServiceClient and retrive the user by object ID using the Object ID copied in the step above.
