Summary of Key Microsoft 365 Copilot Updates (from the subtitles)

The video covers 8 new Microsoft 365 Copilot updates, focused on:

  • New/updated AI model options
  • Improvements across Microsoft Word, Excel, PowerPoint, and Teams
  • Changes to the Copilot app UI/experience

1) Copilot AI model improvements (model choice + better responses)

GPT 5.5 model options added to the Copilot model selector

  • “Instant response”: quick drafting with faster output
  • “Think deeper”: slower but more thorough reasoning

The host demonstrates selecting these modes to draft an email.

Anthropic/Claude enhancements

  • A new Opus 4.8 model becomes available in Microsoft Excel.
  • Opus 4.8 also becomes the default model in Claude Co-work to improve results inside that tool.

Takeaway: enable/select the new models for improved performance.

2) Microsoft Word: model choice for AI writing + better document change awareness

Claude/Anthropic model support in Word

  • Previously unavailable for writing content inside Word.
  • Now available in Word on the web via the Copilot sidebar model selection.
  • Example shown: rewriting an executive summary to be more concise using a Claude “Sonnet/Opus”-type model.

Catch up on recent file changes in Word

  • Copilot can answer prompts like “catch me up on the most recent changes.”
  • It highlights what’s new and summarizes differences across different document versions.

3) Microsoft Excel: “plan before changing” workflow for safer edits

New Plan option (in the Copilot sidebar)

  • When using Copilot with Allow editing, a new option “plan” appears.
  • Instead of applying edits immediately (risking unwanted autosaves), Copilot plans changes first.

Demo workflow

  • The host prompts Copilot to:
    • review the dataset,
    • add columns,
    • create pivot tables and charts.
  • Copilot asks clarification questions, such as:
    • which calculated fields to create,
    • what to break down,
    • chart type and where to place charts (new sheet vs existing dashboards).
  • Copilot then returns an explicit plan for approval.

After approval

  • Copilot applies only the agreed changes, intended to improve outcomes for shared or large workbooks.

4) Copilot app UI/experience changes (Work/Web toggle removal)

Work/Web toggle removed

  • The “work and web” toggle is removed in the Copilot app UI (for the host’s licensed account).

Replacement behavior: Work IQ

  • Introduces Work IQ, which:
    • looks across your work data to answer questions.
  • The UI shifts away from the old toggle concept:
    • “Work IQ” versus web-only behavior is differentiated by the response path.

File attachment flow update

  • When Work IQ is enabled, attachments are added via a plus icon (instead of the previous attachment icon).

Navigation changes

  • Agents access updated (agent selection panel + dropdown).
  • The new conversation stays on the left, and the app launcher/waffle returns.
  • Apps are available under Apps & more.

5) PowerPoint: agentic “prepare for questions” feature

New skill: “prepare for questions”

  • In the Copilot sidebar (under All skills), choose “prepare for questions.”

What it does

  • Copilot reviews the slide deck and identifies likely question triggers.
  • It asks for audience context (example used: “local council and planning,” in-person presentation, decisions/approval context).

Output: anticipated questions + gaps to address

  • Copilot generates potential objections/questions and suggests missing areas.
  • Examples of detected missing elements:
    • unclear site/burough/land status details,
    • missing budget/cost/funding model,
    • missing delivery timeline,
    • missing comparison to alternative land uses.

Overall goal: prepare responses before presenting.

6) Teams meeting recaps: delete meeting recap content (permission-limited)

Recap deletion is now supported

  • Meeting recap content can be deleted.
  • Only the meeting organizer can delete the recap.

How to delete (host walkthrough)

  • Open the recap view (Teams recap)
  • Use the three-dot menu → delete recap content

Important limitation

  • Once deleted, it’s not recoverable—only delete when recap content is no longer needed.

Example scenario

  • If meeting time was wasted on unrelated topics (e.g., holiday plans), you can remove that content from the recap.

Reviews / guides / tutorials mentioned

  • The video is framed as a guide/update walkthrough for the new Copilot features.
  • It references a separate deep-dive tutorial specifically on Copilot app experience changes (linked in the description).
  • Additional learning suggested via “Your 365 Coach” and master classes.

Main speakers / sources

  • Main speaker: the video host (e.g., “today I’ll be covering…,” and “me and the team at your 365 coach…”).
  • Primary product source: Microsoft 365 Copilot (Word, Excel, PowerPoint, Teams, Copilot app)
  • Model sources referenced:
    • OpenAI (GPT 5.5)
    • Anthropic/Claude (Opus 4.8 / Sonnet-type models)
