Microsoft has officially released a major update for Microsoft Teams , this time focusing on mobile users (Android, iOS) working within Windows virtual environments . The update, released on March 18, 2026, introduces the new WebRTC Redirector service , bringing noticeable improvements in communication performance and stability.
This particular development mainly concerns users connecting via Azure Virtual Desktop and Windows 365 from iOS and Android devices (a scenario that has become particularly prevalent in the modern hybrid work model).
The problem of virtual meetings in mobile environments
Until now, using applications like Teamsthrough virtual desktops on smartphones and tablets has come with significant limitations. Audio and video was done entirely on the remote system, resulting in increased latency, lower call quality, and high bandwidth consumption.

This meant that every video call or online meeting depended on the continuous transfer of data via the virtual session, something that often created obstacles to smooth communication — especially on networks with limited bandwidth.
WebRTC Redirector: Changing the philosophy in media processing
Microsoft's new approach is based on moving multimedia processing from the cloud to the user's device . Through the WebRTC Redirector service, audio and video are now processed locally on the phone or tablet , while the rest of the application's functionality remains in the secure cloud environment
This architectural change dramatically reduces the need for continuous data transfer and enables the creation of direct media streams. The result is smoother calls, lower latency, and overall better user experience, even on unstable networks.
Improved experience for users and IT departments
For end users, the differences are immediately noticeable: more stable connections, clearer sound, and fewer interruptions during meetings. This is especially important for workers who rely on mobile devices for their daily communication.
From the IT teams' perspective, the benefits are equally significant. Offloading the processing load to users' devices reduces pressure on the servers, allowing better resource management and more efficient scaling of the infrastructure.

Less load for cloud infrastructures
At the architectural level, the new approach reduces the need for CPU and memory intensive cloud hosts. Video encoding and decoding processes, which traditionally require significant resources, are now performed locally.
This means organizations can support more users per virtual machine, while reducing operational costs and increasing the return on cloud infrastructure investments.
Security without compromises
Παρά τη μεταφορά της επεξεργασίας πολυμέσων στη συσκευή, η Microsoft διατηρεί αυστηρά όρια ασφαλείας. Τα δεδομένα και η λογική της εφαρμογής συνεχίζουν να φιλοξενούνται στο cloud, αποτρέποντας την τοπική αποθήκευση ευαίσθητων πληροφοριών.
This is critical for organizations operating in compliance-intensive environments, ensuring that corporate data remains protected without sacrificing the user experience.
Έτοιμο για μαζική υιοθέτηση
After an extensive public testing period, the new technology is now fully available for enterprise use. Organizations leveraging Azure Virtual Desktop or Windows 365 can immediately implement the new capabilities.
The updated version of the application is already available through the official stores for iOS and Android, allowing users to benefit immediately from the improvements.

The next step for hybrid work
This upgrade clearly shows Microsoft's direction: better user experience without compromising security. In a world where hybrid working is now the norm, such technologies are a critical factor for productivity.
As businesses continue to move towards cloud-first models, optimizing the mobile experience is not just an add-on feature — it's a prerequisite for the future of digital collaboration.
