Microsoft 365 is the world's most widely deployed productivity platform — but most organisations use less than 30% of what they are paying for, leave critical security settings at insecure defaults, and have no backup for the data they entrust to it. Infraspine's M365 service covers the complete journey: migration with zero downtime, proper security configuration, Teams and SharePoint deployment your staff will actually use, genuine backup, and ongoing administration so your platform stays optimised as Microsoft keeps adding capabilities.
A Forrester study found that organisations that deploy Microsoft 365 without proper configuration and adoption strategies achieve less than a third of the potential ROI. The most common gaps: MFA not enforced (leaving accounts vulnerable to credential stuffing), Defender features disabled or at default sensitivity (missing significant threat protection), SharePoint and Teams used as a file dump rather than a structured collaboration environment, and no backup despite Microsoft explicitly disclaiming responsibility for data loss.
The cost impact is real. A single compromised M365 account without MFA typically leads to email phishing of your contacts (reputation damage), access to all SharePoint and OneDrive files (data breach), and sometimes Business Email Compromise fraud (financial loss). Microsoft reports that organisations with MFA enabled block 99.9% of automated account compromise attacks. That single configuration change — which takes minutes to enforce — dramatically changes your security posture.
Teams adoption is the other major value lever. Organisations where Teams is properly structured around workflows see 15–20% productivity improvements from reduced email volume, faster decision-making, and better document collaboration. Getting there requires an architecture design, not just turning Teams on and hoping staff figure it out. Our deployment service includes governance design, team structure, and adoption training that gets your organisation to productive Teams usage within the first 30 days.
Common M365 Mistakes We Fix
From initial tenant setup and zero-downtime migration through to security hardening, backup, and ongoing administration.
A Microsoft 365 tenant deployed with default settings leaves a significant amount of security and productivity capability on the table. Our tenant setup service configures your M365 environment properly from day one: custom domain verification, Exchange Online mail flow rules, spam and phishing protection, conditional access policies, MFA enforcement for all users, Entra ID (Azure AD) synchronisation from on-premise Active Directory, and Microsoft Secure Score optimisation. We document every configuration decision so your team understands exactly what has been set and why.
Email migration is one of the most disruptive IT projects an organisation can undertake if done incorrectly — and one of the smoothest when done right. Our migration methodology uses a pre-migration synchronisation period where all existing email is copied to Exchange Online before the cutover, so when MX records are updated, users immediately have access to their complete historical mailbox. We support cutover, staged, and hybrid migrations from on-premise Exchange, hosted Exchange, Gmail Workspace, and other mail platforms. Post-migration support covers any delivery or configuration issues that emerge in the first 30 days.
Microsoft Teams is Microsoft 365's most transformative application — but also the most underutilised when deployed without proper governance. We design your Teams architecture to reflect how your organisation actually works: team structures aligned to departments, channels structured for workflow rather than conversation chaos, SharePoint document library design that replaces shared drives, and meeting room configuration for hybrid working. External collaboration policies, guest access controls, and data residency settings are configured to balance productivity with security.
Microsoft 365 includes data redundancy but not backup. Microsoft explicitly states in their service agreement that they are not responsible for data loss caused by user deletion, ransomware, or sync errors. The deleted items retention period (30 days by default, maximum 93 days) is not a substitute for backup. We deploy purpose-built M365 backup solutions — Veeam Backup for Microsoft 365 or Acronis Cyber Protect Cloud — that take multiple daily backups of Exchange, Teams, SharePoint, and OneDrive with unlimited retention and point-in-time recovery to any date.
Microsoft 365 Defender provides enterprise-grade email security, endpoint protection, identity protection, and cloud app security within the M365 ecosystem. We deploy and configure Defender for Office 365 (anti-phishing, Safe Links, Safe Attachments), Defender for Endpoint on all managed devices, Microsoft Purview Data Loss Prevention policies to prevent sensitive data leakage, and Azure AD Identity Protection to detect and respond to compromised account activity. Security posture is tracked continuously through the Microsoft Secure Score dashboard.
Microsoft 365 is not a deploy-and-forget platform. Microsoft releases hundreds of new features, policy updates, and security patches every year. Our ongoing M365 administration service handles user lifecycle management (onboarding, offboarding, licence assignment), licence optimisation (right-sizing your licence tier as your needs evolve), policy updates as Microsoft releases new security features, and monthly health reports covering licence usage, security posture score, mailbox storage, and SharePoint growth trends.
