How to reduce IT costs using Microsoft 365

For many UK SMEs, Microsoft 365 has become the invisible backbone of daily operations. It is the environment where emails are sent, documents are drafted, and sensitive client data is stored. However, because it is so deeply integrated into our workflows, it is also an area where "licence sprawl" and inefficient configurations often go unnoticed. For a growing business, these seemingly minor monthly costs can aggregate into a significant, unnecessary drain on annual budgets. Reducing IT costs within Microsoft 365 isn't about cutting corners or sacrificing security; it is about aligning your subscription model with your actual business requirements and leveraging the powerful tools you are already paying for to replace expensive third-party alternatives.

1. Conduct a Rigorous Licence Audit

The most common source of wasted IT expenditure is the "set it and forget it" approach to Microsoft 365 licensing. When a new employee joins, they are often assigned a premium licence—perhaps a Business Premium or E5—simply because it is the "standard" choice. Months later, if that role changes or if the employee leaves, that licence often sits dormant or remains over-provisioned for the user's actual needs.

How to optimise your licence spend:

• Identify inactive users: Use the Microsoft 365 admin centre to view usage reports. If a user hasn’t logged in for 30 days, investigate whether they still require a licence.
• Match licences to roles: Not every employee needs the full suite of advanced security and compliance tools. Front-line staff or warehouse operations may only need the base Business Basic plan, which provides email and web-based apps, while your senior leadership or finance team may require the advanced features found in Business Premium.
• The "Unassigned" trap: Ensure that licences removed from departed employees are unassigned immediately. Many businesses continue to pay for these licences for months after a staff member has left because the offboarding process wasn't fully completed.

2. Consolidate Your Tech Stack

One of the most effective ways to lower your total cost of ownership (TCO) is to stop paying for third-party software that Microsoft 365 already provides. Many UK SMEs pay for standalone cloud storage, signature management tools, or basic project management software, forgetting that these capabilities are included in their subscription.

Opportunities for consolidation:

• Cloud Storage: If you are paying for Dropbox, Box, or Google Drive, you are likely duplicating costs. Migrating to SharePoint and OneDrive provides a secure, GDPR-compliant repository that is already integrated into your existing security policies.
• Communication Tools: If you are paying for Zoom or Slack, evaluate whether Microsoft Teams can fulfil those requirements. Teams has evolved into a robust hub for video conferencing, file sharing, and project collaboration, eliminating the need for fragmented subscriptions.
• Security Add-ons: Business Premium includes Microsoft Defender for Business. If you are paying for a separate third-party antivirus for every machine, you are paying for protection that is already built into your M365 stack.

3. Leverage "Cyber Essentials" and Built-in Security

In the UK, achieving Cyber Essentials certification is a vital milestone for SMEs, particularly those bidding for government contracts or working with large enterprises. A common misconception is that you need to purchase expensive, external security appliances or software to meet these standards. In reality, Microsoft 365 Business Premium contains the essential security controls required to satisfy the Cyber Essentials framework.

By configuring Conditional Access policies, Multi-Factor Authentication (MFA), and Microsoft Intune (all included in the suite), you can secure your environment without purchasing additional security layers. This not only reduces your software bill but also lowers the administrative burden on your IT team, as they no longer need to manage multiple disparate security dashboards.

4. Automate Administrative Tasks with Power Automate

Time is money. When your staff spend hours manually copying data from emails into Excel sheets or chasing approvals via phone calls, your business is losing money. Microsoft 365 includes Power Automate, a powerful tool that allows you to create automated workflows between your apps.

Practical examples of cost-saving automation:

• Automated Onboarding: Trigger a workflow that creates a new user profile, sets up their email signature, and sends them a "Welcome" document the moment they are added to your HR system.
• Approval Processes: Replace manual email chains for expense claims or holiday requests with automated workflows that notify managers and log the outcome directly into a SharePoint list.
• Data Archiving: Automatically move attachments from incoming invoices to a secure folder in SharePoint, reducing the manual labour associated with accounts payable.

By investing a small amount of time in setting up these "flows," you free up your team to focus on revenue-generating activities rather than administrative maintenance.

5. Implement Data Governance to Reduce Storage Costs

While cloud storage is relatively inexpensive, it is not infinite. Over time, "data rot"—the accumulation of redundant, obsolete, or trivial (ROT) data—can lead to increased storage requirements and, more importantly, increased risk. Under the UK GDPR, you have a legal obligation to manage personal data responsibly. Keeping vast amounts of unnecessary data increases your storage costs and your liability in the event of a breach.

Strategies for storage efficiency:

• Retention Policies: Use Microsoft Purview to set automatic retention policies. You can configure the system to automatically delete or archive data after a set period (e.g., 7 years for financial records), ensuring you aren't paying to store digital clutter.
• SharePoint Clean-ups: Regularly audit your SharePoint sites. Often, large files from past projects are left sitting in active libraries. Moving these to cheaper "cold" storage or deleting them entirely will streamline your environment.
• Employee Training: Encourage a culture of "clean digital hygiene." If employees know where to save files and why it matters, you will generate significantly less duplicate data.

Key Takeaways

Reducing your IT spend with Microsoft 365 is an exercise in discipline and strategic configuration. By following these steps, you can ensure your business is not just spending less, but spending smarter:

• Audit regularly: Review your licence count monthly to ensure you aren't paying for users who no longer exist or don't need premium features.
• Eliminate redundancy: Audit your current tech stack and migrate away from third-party tools that duplicate functions already present in your M365 subscription.
• Prioritise built-in security: Use Business Premium features to meet Cyber Essentials standards, removing the need for additional third-party security subscriptions.
• Embrace automation: Utilise Power Automate to eliminate manual, time-consuming administrative tasks.
• Govern your data: Implement retention policies to stay compliant with ICO regulations while reducing your storage footprint.

As a UK SME, your IT strategy should be a driver of growth, not an anchor of unnecessary expense. By optimising your Microsoft 365 environment, you can improve your security posture, increase operational efficiency, and significantly reduce your bottom-line IT costs.
