Programming Office 365: Hands On with Microsoft's new APIs

Half-baked samples – is this stuff really ready?


Trying a sample

The first sample I tried was called How to use Discovery Service.

The app ran, but gave errors including “bad request”, and “the key was not present in the dictionary".

I discovered that the documentation for the sample is missing a critical step. In the Azure AD portal, you have to configure permissions for the application. I did that and the sample ran perfectly.

What if you want to write a file to SharePoint? I turned to another sample, called Office 365 APIs Starter Project. I have had partial success with this sample. At first I could not get it working. The Nuget package manager for Visual Studio could not restore the packages, the documented fix did not work, and then after twiddling with the clientID and redirect URI I was able to run the app and sign in, but got a permission error trying to access resources.

The Office 365 Starter app

However, I tried on another machine and it installed and ran perfectly — but only if I log in with an Office 365 global administrator. If I log in as an ordinary user I get our old friend “bad request”.

I have yet to try the iOS and Android libraries, and of course it is possible that the experience here is better, or that I was just unlucky. Most of the issues seem to be permission-related, and it would help to have a clearer description of all the permission ducks that have to be in line for this to work.

Registering mobile apps with Azure AD is still in preview

Registering mobile apps with Azure AD is still in preview

Despite Microsoft’s TechEd announcement of general availability of Android and iOS SDKs, some of this stuff appears still to be in preview. Native client applications (for Windows or mobile devices) are still marked as preview in the Azure management portal. I do not envy anyone trying to write an iOS or Android Office 365 client equipped only with Microsoft’s sparse "Getting Started" documentation.

Google does a better job of documenting its API for Google Apps, and its sample .NET code for writing a document to Google Drive is refreshingly simple compared with Microsoft’s effort.

It is inevitable that if Microsoft sustains the momentum behind Office 365, there will be increasing demand for mobile apps that integrate with the service. Providing mobile SDKs is a critical step, but the initiative needs better documentation and samples, together with a more coherently organised developer site. ®

    Plus: A drug designed by machine learning algorithms to treat liver disease reaches human clinical trials and more

    In brief Prisons around the US are installing AI speech-to-text models to automatically transcribe conversations with inmates during their phone calls.

    A series of contracts and emails from eight different states revealed how Verus, an AI application developed by LEO Technologies and based on a speech-to-text system offered by Amazon, was used to eavesdrop on prisoners’ phone calls.

    In a sales pitch, LEO’s CEO James Sexton told officials working for a jail in Cook County, Illinois, that one of its customers in Calhoun County, Alabama, uses the software to protect prisons from getting sued, according to an investigation by the Thomson Reuters Foundation.

    Another terrible launch, but DICE is already working on improvements

    The RPG Greetings, traveller, and welcome back to The Register Plays Games, our monthly gaming column. Since the last edition on New World, we hit level cap and the "endgame". Around this time, item duping exploits became rife and every attempt Amazon Games made to fix it just broke something else. The post-level 60 "watermark" system for gear drops is also infuriating and tedious, but not something we were able to address in the column. So bear these things in mind if you were ever tempted. On that note, it's time to look at another newly released shit show – Battlefield 2042.

    I wanted to love Battlefield 2042, I really did. After the bum note of the first-person shooter (FPS) franchise's return to Second World War theatres with Battlefield V (2018), I stupidly assumed the next entry from EA-owned Swedish developer DICE would be a return to form. I was wrong.

    The multiplayer military FPS market is dominated by two forces: Activision's Call of Duty (COD) series and EA's Battlefield. Fans of each franchise are loyal to the point of zealotry with little crossover between player bases. Here's where I stand: COD jumped the shark with Modern Warfare 2 in 2009. It's flip-flopped from WW2 to present-day combat and back again, tried sci-fi, and even the Battle Royale trend with the free-to-play Call of Duty: Warzone (2020), which has been thoroughly ruined by hackers and developer inaction.

  • American diplomats' iPhones reportedly compromised by NSO Group intrusion software

    Reuters claims nine State Department employees outside the US had their devices hacked

    The Apple iPhones of at least nine US State Department officials were compromised by an unidentified entity using NSO Group's Pegasus spyware, according to a report published Friday by Reuters.

    NSO Group in an email to The Register said it has blocked an unnamed customers' access to its system upon receiving an inquiry about the incident but has yet to confirm whether its software was involved.

    "Once the inquiry was received, and before any investigation under our compliance policy, we have decided to immediately terminate relevant customers’ access to the system, due to the severity of the allegations," an NSO spokesperson told The Register in an email. "To this point, we haven’t received any information nor the phone numbers, nor any indication that NSO’s tools were used in this case."
