Microsoft is introducing a noteworthy update to its Teams Mobile application on both Android and iOS platforms. This update, set to roll out in late February 2026, modifies how links to non-Office documents and PDFs are managed within the app.
New Browser Selection Prompt
Starting in late February 2026, users tapping on links that lead to files other than Office documents such as Word, Excel, or PowerPoint, and PDFs, will encounter a browser selection prompt. This change aims to bolster both security and user experience by steering users towards Microsoft Edge.
When users interact with a relevant link, a bottom-sheet pop-up will appear, prompting them to choose their preferred browser. Microsoft is advocating for Edge due to its Single Sign-On (SSO) capabilities, integrated Copilot features, and enhanced security controls tailored for enterprises.
Implementation Across Tenant Types
Should users opt for Edge without having it installed, they will be directed to download the browser to proceed. The update is slated to be implemented across Worldwide, Department of Defense (DoD), Government Community Cloud (GCC), and GCC High tenants, with completion anticipated by late February 2026.
The feature is activated by default across all tenants, eliminating the need for manual actions from organizations. Nevertheless, IT administrators can manage this feature using PowerShell with the TeamsMobilityPolicy policy, specifically through the LinksInTeams attribute.
Administrative Controls and User Customization
Administrators have the option to either maintain the browser selection prompt with the OfferBrowserOptions value or disable it by selecting UseSystemDefaults, which reverts to the device’s default browser setting.
Microsoft has informed administrators via message ID MC1216263 to examine their current TeamsMobilityPolicy settings and adjust their internal documentation as necessary. It is also advised that helpdesk personnel be prepared to address queries about this new browser-selection feature.
For users wishing to personalize their experience, the setting is accessible in the Teams Mobile app. By tapping their profile icon, navigating to Settings, and selecting Links in Teams, users can manage their browser preferences.
Microsoft assures that there are no compliance issues associated with this update. However, organizations are encouraged to review this change against their own policies. The company plans to track user satisfaction, Edge installation rates, and retention metrics during the rollout to assess adoption and address any issues.
