Assessment Reasoning
This is a new feature adding Copilot options for PDF review in OneDrive iOS, expanding existing functionality already available on desktop. Admin impact is moderate due to potential licensing checks and updating user guidance, but no mandatory configuration changes. User impact is noticeable as it introduces a new workflow for mobile users. Urgency is moderate because rollout is planned soon, but no immediate admin actions are required.

📢 Official Microsoft Message Center Announcement

Microsoft 365 Copilot: Review PDFs using the Copilot context menu on OneDrive iOS
Message ID: MC1470417

[What and why:]

Microsoft 365 Copilot makes PDF reviews faster and easier on mobile. Select text in any PDF in OneDrive iOS and tap Ask Copilot to explain, summarize, translate, or ask a custom question about the selection — the same in-context Copilot experience already generally available on desktop, now on OneDrive iOS.

[When this will happen:]

General Availability (Worldwide, GCC, GCC High, DoD): We will begin rolling out late September 2026 and expect to complete by late October 2026.

[Impact on your organization:]

When this rolls out, users viewing a PDF in OneDrive iOS can select text and see Ask Copilot in the context menu. Tapping it opens Copilot with the selected text as context, so they can:

  • Explain dense or technical passages in plain language
  • Summarize long sections
  • Translate into another language
  • Custom prompt: add their own prompt for tailored results — no need to switch apps

The feature is on by default where Copilot is enabled.

Steps to use Ask Copilot in OneDrive iOS:

  1. Open the OneDrive app on iOS and sign in with your work account.
  2. Open the PDF you want to review.
  3. Select any text in the PDF. The context menu will display Ask Copilot.
  4. Tap Ask Copilot for a plain-language explanation or type your own prompt for tailored results.

Licensing requirements

A Microsoft 365 Copilot license is required to use this feature.

[Action required / Recommendations:]

No admin action is required. You may want to:

  • Review your Copilot license assignments for mobile users.
  • Update user-facing training/help content to mention Ask Copilot in PDFs on OneDrive iOS.
  • Notify your help desk of the new entry point.

Note: Some users may see this feature before others in your organization.

[Compliance considerations:]

This feature follows your existing Copilot data-handling and enterprise data protection commitments. Review as appropriate for your organization.
