Hamburg, November 13, 2026. When emails stop being delivered, calendars become inaccessible, or core communication services go down, a technical glitch can quickly turn into a serious business problem. Recent reports of outages affecting Microsoft Outlook and other cloud services have therefore once again brought a fundamental question to the forefront: To what extent should companies rely on individual international technology providers?

In its latest coverage, *WirtschaftsWoche* examines Germany's significant dependence on American software solutions. In fact, email communication, schedule management, and digital collaboration in many companies are now closely tied to a handful of large platforms.

For Hamburg-based OIT.One Solutions LLC, this development is an opportunity to highlight the importance of independent communication infrastructures. The company already offers its own groupware solution that enables key corporate communication functions to be provided outside the traditional Microsoft 365 environment.

When Comfort Becomes a Critical Dependency

Cloud services have fundamentally transformed corporate IT in recent years. They enable the rapid deployment of applications, reduce internal administrative overhead, and simplify collaboration across organizational boundaries.

However, these advantages are accompanied by an increasing concentration of business-critical functions among a small number of providers.

If a critical service goes down, the effects are often immediately noticeable. Employees can no longer communicate as usual, important information is temporarily unavailable, and business processes come to a standstill.

This situation becomes particularly problematic when companies no longer have independent communication channels or technical alternatives.

„Many companies have centered all their communications on a single platform for years. As long as everything works, this seems efficient. However, when a disruption occurs, it becomes clear just how dependent their ability to act has become on the decisions and technical processes of an external provider,“ explains Tim Schulze, managing director of OIT.One Solutions LLC.

The point here is not to fundamentally question the capabilities of established cloud platforms. Rather, companies need to assess the risks associated with complete dependence and the options available for mitigating those risks.

OIT.One offers a standalone groupware alternative

With its own groupware solution, OIT.One is pursuing an approach designed to give companies greater control over their business communications.

The solution is designed specifically for organizations that do not wish to operate central communication services exclusively through international cloud platforms.

The focus is on an independently operated communications environment that can be tailored to a company's specific needs.

OIT.One thus offers an alternative for companies that want to design their IT infrastructure more thoughtfully and reduce their dependence on individual software vendors.

A key advantage lies in the ability to better align technical architecture, security requirements, and operational processes with the actual needs of the respective organization.

„We have been involved in the development and operation of complex IT infrastructures for many years. In the course of our work, we regularly observe that while companies use modern applications, they simultaneously have less and less control over the underlying infrastructure of their own communications. With our groupware solution, we offer an alternative that puts greater emphasis on control and customization options,“ said Schulze.

This solution is not intended as a blanket rejection of Microsoft or other international technology providers. Rather, it expands the technical options available to companies that wish to establish a more independent communication strategy over the long term.

Digital sovereignty must work in day-to-day business operations

The concept of digital sovereignty has been debated for years at the political and economic levels. In practice, however, it often remains unclear how companies can actually achieve it.

For many organizations, a complete overhaul of existing IT systems is neither realistic in the short term nor economically feasible.

Existing business processes, applications, and workflows are too closely tied to the established platforms.

OIT.One therefore takes a pragmatic approach: Companies should be able to decide for themselves which services they want to continue obtaining from the cloud and which parts of their IT infrastructure they would like to operate more independently.

Corporate communications, in particular, offers an important starting point in this regard.

Email systems, calendars, and other groupware features are among the key tools for day-to-day business operations. At the same time, these services can generally be provided outside of the major international cloud ecosystems.

„For us, digital sovereignty does not mean doing without modern technologies. It means having choices and being able to make informed decisions about our own IT infrastructure. A company should not have to wait until a widespread disruption occurs to realize that it no longer has any realistic alternatives,“ Schulze emphasizes.

Security and availability are not a matter of company size

In addition to reliance on individual providers, data protection, information security, and business continuity also play a crucial role.

Business emails often contain confidential information, personal data, or documents that are essential to day-to-day operations.

Consequently, the demands placed on a reliable communications infrastructure are correspondingly high.

An independently operated groupware solution can provide companies with additional options for technical security measures, data processing, and integration into existing security frameworks.

However, independence does not automatically mean higher availability.

Even independently operated systems require professional administration, regular security updates, reliable data backups, and appropriate contingency plans.

Therefore, it is not just the choice of software that is crucial, but the quality of the entire technical architecture.

OIT.One combines its groupware solution with its many years of experience in operating business-critical IT infrastructures and securing complex corporate networks.

„Those who can design their own communications infrastructure gain greater flexibility. While this doesn’t replace professional IT support, it does allow for much more informed decisions about how availability, security, and operations are organized,“ explains Schulze.

Dependence on U.S. technology is becoming a strategic issue

The current discussion has now gone far beyond individual technical glitches.

International trade relations, regulatory developments, data protection requirements, and geopolitical uncertainties mean that companies must increasingly consider their dependence on global technology platforms from a strategic perspective as well.

For European companies, this raises not only the question of which software currently provides the desired functions, but also how reliably, cost-effectively, and independently their own IT systems can be operated in the long term.

This does not necessarily mean completely doing away with American technology.

Rather, alternative platforms and independently operated solutions can help limit critical dependencies and create additional options for action.

Small and medium-sized businesses, in particular, face the challenge of having to make these decisions with limited human and financial resources.

OIT.One sees this as an important role for specialized IT service providers: not only to provide companies with individual software products, but also to support them in developing IT strategies that are sustainable in the long term.

Independence begins with a conscious decision

The recent outages at Microsoft once again highlight that even large, professionally managed cloud platforms are not completely immune to outages.

For companies, this should serve as an opportunity to review existing dependencies and evaluate potential alternatives at an early stage.

A complete IT overhaul is not absolutely necessary for this. Even the targeted decoupling of individual business-critical services can be an important step.

With its proprietary groupware solution, OIT.One offers companies the opportunity to make their communications infrastructure more independent and gain greater long-term control over key digital business processes.

„The real challenge isn’t that large cloud platforms occasionally go down. Technical glitches will always happen. The problem arises when companies are completely dependent on a single provider and no longer have a viable alternative. That’s exactly where we need to start,“ Schulze summarizes.

For OIT.One, one thing is clear: The future of enterprise IT does not necessarily lie in a complete move away from the cloud, but rather in a more deliberate distribution of responsibility, infrastructure, and technological dependencies.

Digital sovereignty begins when companies once again have real choices.
