Microsoft 365 Copilot adds advanced reasoning from GPT-5.5
Microsoft has rolled out GPT-5.5 Thinking to Copilot Chat, Word, Excel and PowerPoint. This brings deeper analysis and multi-step reasoning to everyday tasks in these apps. ChatGPT Images 2.0 launches in PowerPoint Copilot for creating visuals from prompts. It will reach Copilot Chat soon. The features are appearing progressively to users. Known as GPT-5.5 Reasoning in Copilot Studio, the upgrade focuses on complex workflows without needing external tools.
Copilot previously churned out generic replies that crumbled under real M365 pressures like buried emails or fragmented tasks, leaving users to manual fixes. GPT-5.5 now chains logic across steps in your apps, spotting priorities in inboxes or distilling meeting recaps that older versions fumbled. This shifts automations from novelties to workflow anchors, cutting context switches that steal your day.
Analysis
This upgrade finally arms Copilot to fight your inbox overload and task scatter without the gimmick feel. Open Copilot Chat now, dump your last 20 emails in, and prompt for a ranked action list with deadlines. If it halves triage time, pin it as your daily starter; ditch otherwise and stick to rules.
