Microsoft is launching Copilot Cowork via the Frontier program, integrating Claude Cowork’s technology into Copilot to handle long-running, multi-step work. Copilot Cowork makes it easy to delegate and complete work. Describe the outcome you want, and it creates a plan, reasons across your tools and files, and carries work forward with visible progress and opportunities to steer. With skills from Claude and Microsoft built in, such as calendar management and daily briefing, Copilot Cowork can handle everything from one-off tasks to repeatable workflows.

File-level archiving comes to Microsoft 365 Archive
Microsoft is announcing a public preview of file‑level archiving in Microsoft 365 Archive.

This means you can archive outdated and redundant files while keeping the rest of the site active, improving both your Copilot relevancy and your search results in the process.
In PowerPoint, text is often placed on top of images, gradients, or layered visuals, and most text boxes are transparent by default.
