The European Commission’s trial of Element Pro as a self-hosted fallback for Microsoft Teams is a useful reminder for IT leaders: digital sovereignty is not just a procurement policy. It is a user experience, migration, support, governance, and resilience problem all at once.
According to Windows Latest, the Commission has been testing Element Pro as a sovereign backup to Teams, with the service hosted on its own infrastructure rather than Microsoft’s cloud. The aim is understandable. Governments and regulated organizations want more control over data, continuity, and dependency risk. But early staff reactions reported from internal discussions suggest the alternative is struggling to match the familiarity and polish users expect from Teams.
That tension matters beyond Brussels. Many businesses are asking similar questions about cloud concentration, sanctions exposure, data residency, and operational independence. The EU example shows why replacing a dominant collaboration platform is harder than installing another chat app.
Sovereignty has to work during a normal workday
The case for a sovereign collaboration tool is straightforward. If an organization depends on a foreign cloud provider for messaging, meetings, files, identity integrations, and daily coordination, a legal, political, commercial, or technical disruption could become an operational crisis. A self-hosted or regionally controlled system can reduce that risk, especially for governments and critical sectors.
However, resilience tools only help if people can use them under pressure. In a real outage or geopolitical emergency, staff will not have time to rediscover where calls, files, rooms, permissions, and notifications live. A backup collaboration environment must be rehearsed, documented, accessible, and close enough to the primary workflow that switching does not create more confusion than the incident itself.
That is the practical problem highlighted by the Commission’s Element Pro trial. Teams remains the main tool, while Element Pro is positioned as a fallback. If users rarely rely on the fallback day to day, they may judge it only when something feels different or missing. This is the collaboration-platform version of an unused disaster recovery plan: technically present, but not yet operationally trusted.
Microsoft Teams is hard to displace because it is embedded
Teams is not popular only because it offers chat and video calls. It is tied into Microsoft 365 identity, Outlook calendars, SharePoint files, OneDrive sharing, meeting links, compliance tooling, device management, and a long list of organizational habits. For many users, Teams is where work arrives, not just where conversation happens.
That creates a high bar for any replacement. A rival product can be more open, more sovereign, or more transparent and still feel weaker if calendar joins, file previews, search, notifications, accessibility, mobile behavior, or meeting reliability are worse. Users tend to compare the whole working environment, not the policy justification behind it.
For IT teams, the lesson is to measure collaboration migrations around complete workflows. Can a new platform support a committee meeting, a cross-agency project, an urgent mobile call, a confidential file exchange, and an accessibility-dependent user without special handling? If not, the rollout plan needs more than communication. It needs integration work, training, exception handling, and a realistic adoption timeline.
Open standards do not remove the need for product polish
Element Pro is built around Matrix, an open messaging standard, and the broader idea is attractive: interoperable communication, less single-vendor lock-in, and more control over hosting. Those are real advantages for public institutions and organizations with strict data requirements.
But open architecture does not automatically produce a better front-end experience. End users still care about meeting stability, screen sharing, search quality, mobile notifications, audio device handling, and whether a file opens when they click it. Procurement teams may buy sovereignty, but employees experience latency, interface friction, and missing shortcuts.
This is where many strategic IT projects fail. The business case focuses on risk reduction, while adoption depends on small daily interactions. If a tool is meant to replace Teams, Slack, Zoom, or Google Meet, it must compete with years of refinement and muscle memory. A technically sound system can still face resistance if the product details are not ready.
Teams also deserves scrutiny
The irony is that Teams itself is far from perfect. Windows Latest again points to the resource-heavy nature of the app, including its reliance on WebView2 and high memory usage in some scenarios. Many Windows users have seen Teams consume far more RAM than expected, especially during calls, with backgrounds, or when cache and WebView2 components misbehave.
For Windows administrators, the usual mitigation list still applies: keep Teams and WebView2 updated, clear problematic Teams cache data when symptoms appear, review startup behavior, limit unnecessary visual effects for low-end devices, and monitor meeting-room PCs separately from office desktops. Teams may be deeply embedded, but it should not be exempt from performance management.
The broader point is that Microsoft benefits from being the default, not always from being the most efficient. If governments are reluctant to leave Teams even while criticizing U.S. cloud dependency, Microsoft has both a market advantage and a responsibility to improve the Windows client experience.
Practical guidance for IT leaders
Organizations considering a sovereign or self-hosted Teams alternative should avoid a “big switch” mindset. Start with clearly defined use cases: emergency communications, sensitive project rooms, external collaboration, or departments with specific data residency requirements. Then test those use cases with real users, not just administrators.
Run parallel drills. Publish simple “if Teams is unavailable, use this” instructions. Pre-create rooms and groups. Validate mobile push notifications. Confirm accessibility requirements. Test screen sharing on managed Windows devices. Measure not only uptime, but task completion: could people actually hold the meeting, find the document, and reach the right team?
Most importantly, treat user complaints as implementation data rather than resistance. If staff say the alternative lacks value, that may mean the purpose has not been explained, the workflow is incomplete, or the product is not yet ready for the role assigned to it.
Digital sovereignty is a valid goal, but it is not achieved by replacing a logo. It is achieved when the sovereign option is reliable enough, familiar enough, and practiced enough to keep work moving when the primary platform is unavailable. The EU trial is a warning that independence projects need the same discipline as any other mission-critical IT migration.
