Microsoft Teams Mobile Browser Prompt Rollout

Microsoft Teams mobile apps on Android and iOS will prompt users to choose a browser for non-Office and PDF links starting late February 2026. The bottom-sheet pop-up highlights Microsoft Edge for SSO, Copilot integration, and security features. Users select Edge or default browser; Edge prompts install if missing.

The update targets Worldwide, DoD, GCC, and GCCH tenants. Rollout completes by end of February 2026. Feature improves security and experience by promoting Edge while restoring choice after prior automatic redirects.

Admins control via TeamsMobilityPolicy PowerShell. Enabled by default as OfferBrowserOptions.

Feature Details

When users tap non-Office/PDF links in Teams mobile, a prompt appears. Edge shows first with benefits listed. “Remember my choice” option available.

If Edge unselected and uninstalled, app store redirect follows. Default browser option always present.

User settings in app: Profile icon > Settings > Links in Teams. Toggle browser preference directly.

No compliance impacts identified. Microsoft monitors DSAT, Edge installs, retention metrics.

Rollout Timeline

• Start: Late February 2026
• Completion: End February 2026
• Tenants: Worldwide, DoD, GCC, GCCH
• Platforms: Android, iOS Teams mobile

Prior behavior forced Edge. New prompt gives choice but positions Edge prominently.

User Experience Changes

Positive:

• Browser choice restored
• SSO/Copilot in Edge for M365 users
• Enterprise security controls

Considerations:

• Repeated prompts if “Remember” unchecked
• Edge install nudge for new users
• No third-party browsers listed explicitly

Helpdesks prepare for queries. Update documentation.

Enterprise Implications

Organizations standardize on Chrome/Firefox set UseSystemDefaults proactively. Controlled environments avoid disruption.

Test in pilot groups. Brief users on prompt. Monitor adoption metrics via Microsoft reports.
