  1. Governance & security

    The confident wrong answer is worse than missing evidence

    A governance report told us a site had external sharing disabled. The site permitted anonymous links. Nothing was broken: a correct API returned a default value for a property it had never populated, and the default happened to be the safest word in the enum. Here is the mechanism, the code that reproduces it, Microsoft's own documentation of it, and the discipline that catches the whole class.

    Why SharePoint Framework still runs on React 17

    Fourteen SPFx releases later, SharePoint Framework still runs on React 17. This is not a story about an old framework. It is a story about what has to move before a platform can move.

    Developing for SharePoint Server Subscription Edition: the practices that hold up

    Subscription Edition is supported until at least 2035 and its SharePoint Framework ceiling has not moved since 2023. That combination is the whole job: a long runway on an older stack. This is how to build on it well, with code that runs on the version your farm actually accepts.

    SharePoint 2016, 2019, Subscription Edition and Online: what actually changes

    2016 and 2019 both end support on 14 July 2026. Subscription Edition has no end date and cannot be bought outright. Online has features the others will never get, and Subscription Edition has two that are usually listed as impossible. A practical comparison, with the licensing that decides it.

    Migrating SharePoint 2016 and 2019 to Subscription Edition: the scripts

    SharePoint 2016 goes straight to Subscription Edition. There is no hop through 2019, the method is database attach and nothing else, and the order of the service applications is not a preference. The whole sequence in PowerShell, from the inventory you take before touching anything to the crawl you run at the end.

  6. AI & agents

    A Copilot agent manifest is a security boundary. Here is the linter for it.

    Every scoping property in a Microsoft 365 Copilot agent manifest is optional, and in six places omitting one grants the widest scope instead of the narrowest. A JSON Schema validator approves those manifests, because nothing in them is invalid: something optional is missing. So we wrote the check that does catch it. It finds six problems in a manifest that passes every other test.

    SPFx before version 1.0: our web parts in the official Microsoft samples

    The SharePoint Framework developer preview came out in August 2016. Version 1.0 arrived in February 2017. Our first contribution to the official Microsoft 365 samples repository is dated October 2016, five months before there was a 1.0 to build against. Four of our web parts are in that repository today, and this is what each of them is for.

    SPFx 1.23.2: upgrading is not changing a number

    The previous version was pulled from npm for regressions, and that is the warning: the risk of upgrading the SharePoint Framework is almost never in the SharePoint runtime, it is in the build. What changed in Heft, in Sass and in npm audit, with the code showing how it was, how it is, and how it will be.

  9. Microsoft 365 & SharePoint

    The state of SharePoint in 2026: what is gone, what is current, and what to build on

    Every year someone declares SharePoint dead. It never was. But in a matter of months, real parts of it reached the end of the line: the Add-in model and Azure ACS retired in April, and SharePoint Server 2016 and 2019, InfoPath and SharePoint Designer left support in July. Here is what actually ended, what replaced it, and what to build on now, on-premises and in the cloud.

    Migrating SharePoint without stopping the business

    The hard part of a migration is not moving files. It is that nobody stops working while they move.
