Microsoft Adds Calendar Updates and Claude to Outlook
Microsoft plans to roll out a set of Outlook updates in May 2026 that focus on calendar usability and expanded AI integrations aimed primarily at business users. Web Outlook will gain a redesigned navigation bar that automatically surfaces team and manager calendars and supports third‑party accounts. Users will be able to select multiple calendars and non‑contiguous events using Shift/Ctrl. The desktop Outlook client will receive access to Microsoft Copilot for summarizing selected email text and surfacing contextual information. Microsoft is also enabling third‑party LLM support: Anthropic’s Claude is being offered in Word, Excel and PowerPoint and will enter a beta in Outlook, with cross‑application context retention for workflows spanning documents, spreadsheets and email. The article notes recent removals of Outlook features (Contact Masking) and the planned discontinuation of Outlook Lite on May 25, 2026.
Outlook feature becomes paid in September
Microsoft will remove the free Outlook feature "Meeting Insights" and replace it with a paid AI alternative. The rollout that removes Meeting Insights will begin in some regions mid‑August 2026 and be completed worldwide by early September 2026. The replacement, called "Prepare for this meeting," uses Microsoft 365 Copilot to access accessible emails and documents and summarize relevant information during meeting scheduling. The AI-driven replacement will require a Microsoft 365 subscription: single-user plans cost €99/year, family plans €129/year, and enterprise pricing is around €27 per user per month for Office apps plus Microsoft Copilot.
New Outlook warns when replying to old emails
Microsoft is adding a Thread-Awareness protection to the new Outlook for Windows that warns users if they attempt to reply to an older message while newer messages exist in the same thread. According to Microsoft 365 Roadmap entries, the feature entered testing in early July 2026 and a broad rollout for the Windows client and the web version is planned for the end of August 2026, with enterprise tenants receiving it enabled by default. Microsoft will also introduce the ability to link templates to inbox rules from September 2026 and a sidebar-favorited category/drag-and-drop labeling workflow rolling out through the end of September 2026. The company says the template automation uses deterministic if-then rules rather than large language models. The update aims to reduce support tickets and improve inbox workflows, though the new Outlook client remains controversial among users.
