Microsoft 365 Business Premium

Microsoft 365 Business Premium brings together the Microsoft apps your team already knows, including Outlook, Teams, Word, Excel, and PowerPoint, with business email, cloud storage, device management, and advanced security in one licence. It is designed for organisations with up to 300 users and is a strong fit for professional firms, especially accountancy practices and law firms, that need their people to work efficiently while keeping client and company data properly protected.

What’s included in Microsoft 365 Business Premium

• Familiar Microsoft apps across every device: Give your team access to desktop, web, and mobile versions of the Microsoft 365 apps they use every day, helping them work consistently whether they are in the office, at home, or travelling.
• Business email and calendars: Use Outlook and Exchange for professional email, shared calendars, and contacts, with support for custom business email addresses.
• Teams and OneDrive: Keep communication and collaboration connected with Teams for chat, meetings, and calls, and OneDrive for secure file storage and sharing, with 1TB of cloud storage per user.
• Device and app management with Intune: Manage laptops, mobiles, tablets, apps, and security policies more effectively through Microsoft Intune, helping your firm stay consistent and controlled as users and devices grow.
• Advanced protection against cyber threats: Business Premium includes Microsoft Defender for Office 365 to help protect against phishing, ransomware, and email-based threats, as well as Microsoft Defender for Business for device protection and vulnerability management.
• Stronger identity and access control: Microsoft Entra ID P1 is included, giving firms more advanced identity protection and access management. This helps you apply stronger controls around who can access business systems and from which devices.
• Protection for sensitive information: Business Premium includes sensitivity labels, data loss prevention, message encryption, and Purview-based information protection features to help classify, protect, and control confidential information in emails and files.

Benefits of Microsoft 365 Business Premium

• A more joined-up way of working: Your team can keep email, calendars, meetings, calls, documents, and collaboration in one connected Microsoft environment, reducing friction and improving day-to-day workflow.
• Better support for hybrid working: Microsoft 365 Business Premium is built to support secure remote and hybrid work, helping firms protect users and data without making everyday work harder than it needs to be.
• Stronger protection for client data: For professional firms, confidentiality matters. With built-in controls for classification, encryption, and data loss prevention, Business Premium helps reduce the risk of sensitive information being shared or accessed inappropriately.
• Simpler IT management: Instead of relying on separate tools for productivity, email, file sharing, security, and device management, Business Premium brings more of what you need into a single platform and licence.
• A stronger foundation for growth: As your business grows, Business Premium gives you a more scalable and manageable setup, with the security and control needed to support more users, more devices, and higher expectations around compliance.

Most professional firms also want stronger visibility, not just security settings. Business Premium gives you excellent protections, and HDUK can help take that further with 24/7 monitoring, alerting, and response through our managed SOC and SIEM service.

Why firms move from Business Standard to Business Premium

If you are already using Microsoft 365 Business Standard, the move to Business Premium is less about changing how your team works and more about improving how securely and effectively your environment is managed. The biggest difference is that Business Premium adds the extra layer of security, identity control, and device management that many firms eventually need as they grow, take on more responsibility, and handle more sensitive information.

How HDUK can help you make the move to Microsoft 365 Business Premium

Choosing the right Microsoft 365 licence is only part of the decision. To get the most from Business Premium, it needs to be rolled out properly, configured sensibly, and aligned to how your firm actually works.

• Plan and deliver a smooth migration: Whether you are upgrading from another Microsoft plan or moving from a more fragmented setup, HDUK can manage the transition carefully to minimise disruption for your users.
• Configure security properly from day one: We can help set up multi-factor authentication, access controls, device policies, email protection, and information protection features so the platform functions as intended from the outset.
• Support your users and internal teams: We provide practical guidance, onboarding support, and day-to-day technical help so your team feels confident using Microsoft 365 properly.
• Keep everything secure and supported over time: After go-live, HDUK can continue to support, monitor, and improve your Microsoft 365 environment as your business grows and your requirements change.
