A Breaking Change for all Android-based Teams Devices
The Model Context Protocol (MCP), now in preview for Microsoft Copilot Studio, enables powerful integrations with external systems—but also introduces new security challenges. This article explores how to securely deploy MCP with Copilot Studio Agents.
I usually reach for the Microsoft Graph PowerShell SDK when I need to automate Microsoft 365 processes. But sometimes, the Graph doesn't work. PnP PowerShell is a great tool for interacting with SharePoint Online, in this instance to check document libraries to find how many have a default sensitivity label configured. The code works, it's reasonably quick, and it's an example of how flexible PowerShell can be in dealing with Microsoft 365.
Microsoft recently announced a breaking change for all Android-based Teams devices.

Ransomware protection isn’t about a single solution; it’s a layered defense strategy. In this article, we explore a few recommendations that organizations can use to significantly reduce risk and combat ransomware in their tenant.
Any time you allow a third-party application to run in a system you own or control, you’re assuming risk. In this episode of Practical Protection, we discuss how to reduce that risk by managing app consent in Microsoft Entra ID, as well as a few other alternatives.
App secrets are used to authenticate registered apps with Entra ID. App secrets (or passwords) are convenient and easy to use, but they're relatively insecure. The default app management policy for the tenant can block app secrets while custom app management policies can allow selective apps to use app secrets for testing or other well-defined purposes. All explained here.
In the second part of this series on Controlling Access to Microsoft 365 Entra ID Apps, Ingo dives into the process of creating custom Role-Based Access Control (RBAC) to Improve Security in your tenant.
A previous article explained how Microsoft 365 usage report data can highlight inactive Copilot users. If we add audit data to the mix, the analysis becomes much richer because we can see exactly what use people make of different Copilot apps, like Word, Chat, Outlook, and so on. Better data means better decisions!
