For many organisations, Microsoft is no longer a collection of individual technologies. It is the foundation that underpins productivity, collaboration, business applications, cloud infrastructure and digital transformation.
But as Microsoft estates continue to grow, so too does the challenge of managing them effectively. From Microsoft 365 and Azure through to Dynamics 365 and business-critical applications, organisations increasingly need specialist expertise across multiple areas of the Microsoft ecosystem to maximise value and drive business outcomes.
That's where the partnership between bluesource and Columbus comes in.
Bluesource and Columbus have partnered to deliver a broad range of cloud and Microsoft services to many of Trustmarque's Tier 1 customers across the public sector, not-for-profit and highly regulated industries.
The partnership combines two highly specialised but complementary areas of Microsoft expertise
As a long-standing and trusted technical MSP+, bluesource was one of Microsoft's first designated Support Partners globally and provides deep expertise across Microsoft 365, Azure and on-premises technologies. Bluesource was also recognised by Gartner as a Representative Vendor in the 2025 Market Guide for Microsoft Product Support Services for the second consecutive year, highlighting its strong reputation for delivering high-quality third-party Microsoft support.
Columbus brings extensive expertise across the Dynamics 365 landscape, helping organisations transform and manage critical business applications, including Dynamics 365 Finance, Supply Chain Management and Business Central. In 2025, Columbus was selected as one of the first 30 partners worldwide to achieve Microsoft's new Support Services Designation, further reinforcing its commitment to customer success and service excellence.
Together, the two organisations offer customers access to specialist support and expertise across both the technology and business application layers of Microsoft's ecosystem.
Too often, organisations are required to engage multiple providers for different elements of their Microsoft estate. One partner may support infrastructure and cloud services, while another manages business applications and processes.
The result can be fragmented ownership, increased complexity and missed opportunities to unlock value across the wider Microsoft platform.
By working together, bluesource and Columbus provide customers with a more joined-up approach.
Whether organisations are looking to optimise Microsoft 365, strengthen their Azure environment, enhance Microsoft support services or transform key business processes through Dynamics 365, they can access the expertise they need through a partnership that spans the full Microsoft landscape.
This coordinated approach helps organisations:
Most importantly, it enables customers to focus on business outcomes rather than managing multiple technology relationships.
The partnership is particularly valuable for organisations operating in complex and highly regulated environments.
Across public sector, healthcare, education, housing and not-for-profit organisations, digital transformation programmes often require expertise that extends beyond technology implementation alone. Success depends on ensuring that cloud infrastructure, collaboration tools, business applications and support services all work together effectively.
The combined capabilities of bluesource and Columbus help organisations navigate these challenges with confidence, providing access to specialists who understand both the technical and operational demands of modern Microsoft environments.
Trustmarque’s Fusion Live, taking place on 17 September at Magazine London, offers an opportunity to see this partnership in action.
Visitors will be able to speak with both the bluesource and Columbus teams to explore how a more connected approach to Microsoft can support their organisation's objectives.
Whether you're looking to optimise Microsoft 365, secure and manage Azure, improve Microsoft support services or transform business processes through Dynamics 365, the partnership demonstrates how bringing together complementary expertise can help organisations reduce costs, improve service delivery, strengthen resilience and unlock greater value from Microsoft.
Because when it comes to maximising the value of your Microsoft investment, the strongest outcomes come from bringing the right expertise together.
