Microsoft Teams to Prompt Mobile Users for Browser Choice with Non-Office and PDF Links

## Product Update: Teams Mobile Browser Selection

Product Update: Teams Mobile Browser Selection

Microsoft has announced an update to the Teams Mobile application, applicable to both Android and iOS platforms. This update modifies the handling of non-Office and PDF links within the application.

Starting in late February 2026, users will encounter a browser selection prompt when they click on links to files that are neither Office documents (Word, Excel, PowerPoint) nor PDFs. The update aims to enhance security measures and improve user experience by promoting the use of Microsoft Edge.

Upon selecting a qualifying link, users will see a bottom-sheet pop-up enabling them to choose their preferred browser. Microsoft Edge is recommended due to its native support for Single Sign-On (SSO) , integrated Copilot features, and advanced security controls for enterprises.

If Edge is chosen and not yet installed, users will be prompted to download it. This update will be deployed across Worldwide, DoD, GCC, and GCCH tenants, with completion expected by late February 2026.

This feature is automatically enabled for all tenants. IT administrators can manage the feature through PowerShell using the TeamsMobilityPolicy policy. The key attribute, LinksInTeams, offers two configurations:

OfferBrowserOptions: Activates the browser selection prompt. UseSystemDefaults: Defaults to the device's existing browser settings, disabling the feature.

Administrators have been advised via Message ID MC1216263 to review current TeamsMobilityPolicy settings and update internal documentation as needed. Helpdesk teams should be informed about the new browser-selection feature to assist users effectively.

Organizations with strict browser configurations may opt to set LinksInTeams to UseSystemDefaults to maintain workflow consistency.

End users can customize their browser preference directly in the Teams Mobile app by accessing the settings via their profile icon and navigating to 'Links in Teams'.

Microsoft has identified no compliance issues with this update, though organizations should review it against their policies. User satisfaction, Edge installation rates, and retention metrics will be monitored throughout the rollout to ensure a smooth adoption process and address any arising issues.
