Can one misconfiguration lock your entire M365 environment?

Can a single misconfiguration lock your entire Microsoft 365 organisation out?

The short answer is yes.

An IT admin recently shared a nightmare scenario: their entire Microsoft 365 tenant became inaccessible overnight. No Teams. No SharePoint. No email. Even the Global Admin was locked out and stuck in an MFA loop with no way in.

What caused it?

A well-intentioned security policy. A Conditional Access rule was enabled requiring Microsoft Authenticator for MFA. But none of the users, including admins, had it configured. The result? Every account got caught in an MFA loop, with no escape and no admin access to undo the change. And without admin access, there’s no rolling the policy back.

So how do you fix it?

The bad news is you can’t – not by yourself. The only option is contacting Microsoft Support, verifying your identity, and requesting a temporary bypass. In this case, it took a 24-hour admin access reset window and hours of back-and-forth with support to get back in.

Avoid this disaster with emergency access accounts.

Microsoft recommends every tenant has at least two emergency (or “break-glass”) Global Admin accounts. These should:

  • Be excluded from all Conditional Access and MFA policies
  • Not be used for everyday tasks
  • Be protected with strong, offline-stored credentials
  • Be closely monitored for any sign-in activity
  • Regularly test the accounts and regenerate the password quarterly

They’re your last resort – use them only in emergencies.

Microsoft Exchange Server 2016 and 2019 end of life: What it means for your business

Microsoft Exchange server 2019 extended support ends this year on the 14th of October along with exchange server 2016. Microsoft are forcing the everyone to be on the latest exchange 2019 CU from this date. 

After these dates, users will be able to in place upgrade to exchange SE edition, but not doing will mean no further security updates, bug fixes, or technical support, posing serious risks to businesses still relying on these platforms.

What does this mean for your business?

Running unsupported Exchange servers leaves organisations exposed to cybersecurity threats, compliance issues, and potential operational disruptions. Without critical updates, businesses are more vulnerable to ransomware, data breaches, and email downtime – directly impacting productivity and trust.

To protect your IT infrastructure and future-proof communications, companies should begin planning their upgrade path now. Options include migrating to Microsoft 365 Exchange Online, a cloud-based solution offering enhanced security, scalability, and access from anywhere. Alternatively, businesses may consider transitioning to a hybrid environment or an updated on-premise solution, depending on specific compliance or data residency requirements.

Your migration path to Exchange Server SE

This transition can be complex, but the expert team at Complete IT Systems are here to help. We provide tailored migration strategies, whether you’re moving to the cloud or upgrading your on-premise systems. We ensure a smooth, secure migration with minimal disruption to your business operations.

With over a decade of experience in Microsoft solutions, Complete IT Systems can guide you through every step—from assessing your current Exchange environment to post-migration support and optimisation. Don’t wait until support ends – get ahead of the risks now.

Windows 10 support is ending: What to expect and how to prepare

Windows 10’s journey is coming to a close. How does this affect your business, and how should you prepare?

Microsoft announced last year that updates for Windows 10 will cease after October 14, 2025, making version 22H2 the final update.

For those who have transitioned to Windows 11, this may not pose a problem. However, if you’re still using Windows 10, you might be wondering what comes next. Here we address your concerns and help you prepare for the transition. As a Microsoft Partner, Complete IT Systems are well-equipped to handle any Microsoft 365 issues you might encounter.

When does windows 10 officially end?

Windows 10 support ends on October 14, 2025, except for Long-Term Service Channels (LTSCs), designed for organisations needing a stable and long-lasting environment with minimal changes. After this date, while you can still use Windows 10, you’ll be at risk of security breaches since new patches won’t be available without payment. This end-date is crucial for businesses reliant on Windows 10, as not all PCs can upgrade due to hardware limitations. We’ll discuss ways to navigate this situation.

Risks of using free Windows 10 after its end date:

  • Security vulnerabilities: Without new updates, Windows 10 devices become more susceptible to cyber threats.
  • Performance degradation: Lack of updates can lead to system instability, crashes, and decreased performance.
  • Lack of support: Microsoft will stop providing support for Windows 10, making troubleshooting difficult.
  • Software compatibility: New software may not be compatible with Windows 10, limiting functionality and potentially making critical applications slower.

Extended Security Updates (ESU)

Microsoft offers Extended Security Updates (ESU) for up to three years, but they come at a cost. There are three options:

  1. Activation key: A base license package costs £48 for the first year, doubling each year for three years.
  2. Cloud-based: Businesses using Microsoft cloud-based update management solutions get a 25% discount for up to five devices.
  3. Windows 365 subscription: Those with a Windows 365 subscription can access ESU services without additional costs for one year.

What are the options?

You have the following options based on your business needs:

  • Upgrade to Windows 11: This ensures your device is protected with the latest security updates.
  • Pay for ESU services: Use one of the ESU options to buy more time to transition to Windows 11.
  • Continue with Windows 10 unprotected: Not recommended due to the significant risks involved.
  • Purchase a new Windows PC or move to Mac OS: New Windows PCs come with Windows 11, or you could switch to a Mac if you prefer.

Benefits of Windows 11

Windows 11 offers numerous advantages:

  • Improved performance: Faster and smoother operation with optimised coding and resource management.
  • Innovative user interface: A revamped UI with a central taskbar, new snap layouts, and an aesthetically pleasing design.
  • Ideal for hybrid working: Features seamless Microsoft Teams integration and enhanced multitasking capabilities.
  • Integrated AI: Includes the AI-powered assistant “Copilot” to help generate ideas and improve productivity.

Traditional storage vs. workload-aware storage: A buyers’ guide

As businesses grow increasingly reliant on resource-intensive environments, choosing the right storage solution has become more critical than ever.

Traditional storage systems, while robust, often struggle to meet the demands of demanding workloads. Enter Tintri’s workload-aware storage, a modern solution designed to optimise resources for virtual machines, databases and containers. This article introduces the advantages of workload-aware storage, and how to find out more about the solutions to evaluate whether they are a good fit for your business.

Traditional vs. workload-aware storage

One of the primary reasons Tintri excels for storage workloads is its ability to provide visibility and control at a granular level. Traditional storage systems often require manual intervention for performance management, capacity planning, and troubleshooting, which can be both time-consuming and error-prone. Tintri, however, eliminates these challenges by offering automated, AI-driven analytics that provide real-time insights into how storage resources are being utilised. This enables organisations to understand exactly how their storage is performing, which applications are consuming the most resources, and where inefficiencies might exist.

Harnessing the power of AI

Tintri’s use of AI plays a crucial role in its optimisation capabilities. The platform utilises machine learning algorithms to monitor and analyse storage behaviour continuously, learning from the data patterns that emerge over time. By doing so, Tintri can predict and prevent potential issues before they impact performance. This proactive approach to storage management reduces the need for manual interventions, ensuring that IT teams can focus on more strategic tasks rather than reacting to issues as they arise.

Another significant advantage of Tintri’s AI-driven storage solution is its ability to optimise workloads for both performance and capacity. Tintri’s Intelligent Data Reduction (IDR) technology helps organisations maximise their storage efficiency by using AI to analyse data patterns and identify opportunities for compression and deduplication. This leads to significant space savings, ensuring that businesses can store more data without needing to invest in additional storage hardware. The use of AI ensures that these operations are carried out in an intelligent and non-disruptive manner, maintaining optimal performance while freeing up valuable storage capacity.

Tintri’s AI-powered analytics engine also simplifies the process of managing and scaling storage environments. With its predictive capabilities, the platform can forecast future storage needs based on usage trends, helping IT teams plan more effectively and avoid over-provisioning or under-provisioning. This not only saves money by ensuring that storage resources are used efficiently but also ensures that organisations are ready for future growth without the risk of performance degradation.

The flexibility to scale

Moreover, Tintri’s platform is designed to be highly flexible, supporting a wide range of workloads, including virtualisation, databases, cloud applications, and more. Whether an organisation is running traditional on-premise systems or hybrid cloud environments, Tintri’s storage solutions can seamlessly adapt to the changing demands of modern workloads. This versatility, combined with AI-driven management, ensures that storage resources are always aligned with the specific needs of the organisation, whether that’s high-performance computing, large-scale data processing, or cost-effective storage consolidation.

In summary

Tintri offers an innovative approach to managing storage workloads, with AI at the heart of its solution. By providing intelligent automation, predictive analytics, and optimised resource management, Tintri ensures that businesses can achieve peak performance, maximise storage efficiency, and reduce operational complexity. As data volumes continue to grow and IT environments become more complex, Tintri’s AI-driven storage solutions are a powerful tool for any organisation seeking to stay ahead in the rapidly evolving digital landscape.

From box tick to value driver: Engaging cyber training to clue up your users

The lack of cyber awareness in UK businesses remains a significant concern, leaving many companies vulnerable to cyber attacks, data breaches, and financial losses.

Despite the increasing sophistication of cyber threats, many organisations, particularly small and medium-sized businesses, fail to prioritise cybersecurity. Last year, a UK government report found that nearly a third of businesses had experienced a cyberattack in the past year, yet many still lack adequate protection measures.

Alongside the fact that many businesses fail to implement basic security requirements, a major issue is the lack of employee training. Phishing attacks and social engineering scams are among the most common threats, yet many employees are unaware of how to recognise and respond to them. Without proper training, human error remains a leading cause of security breaches.

Enough of the bad news – what’s the solution?

Complete IT Systems have partnered with Infinigate, the UK’s leading distributor for KnowBe4, to provide you with a full managed service, designed to make deploying KnowBe4 quick, easy, & hassle-free!

Struggling to deliver educate your users on cyber awareness?

Generic security awareness training is no longer effective in complex work environments. Users either don’t get it, don’t think it applies to them, or thinks “it’s IT’s job”. 

As a result, your organisation may be struggling to deliver relevant, engaging content that changes user behaviour and resonates across different roles, departments, and even languages.

Enough of the bad news – what’s the solution?

KnowBe4’s AIDA (Artificial Intelligence Defense Agents) is an AI-native suite of agents that supercharges your approach to human risk management. It leverages multiple AI technologies to create personalised, adaptive, and highly effective training for all of your users that actually changes behaviour.

By automating template generation, training, and reporting, AIDA reduces the administrative burden on your security teams so they can focus on protecting your network.

Why cyber-resilience matters – and how to achieve it

Today’s word of the day is cyber-resilience. Read on for an overview of the concept, and view an informative webinar to get a more in-depth presentation and answers to your questions.

Cyber-resilience is the ability to bounce back quickly from a cyber incident. And the fact of the matter is that, unless your organisation is very lucky indeed, sooner or later it will suffer a successful ransomware attack.

And if your company has cultivated cyber-resilience, it will be able to recover and return to normal operations quickly and easily. But if it hasn’t, it will find its operations massively disrupted, for weeks or even months. The average time to recover from ransomware is 24 weeks. That’s nearly two quarters. Can your organisation survive a disruption that long – or longer?
