Expert consultancy, technical mentoring, and advanced 3rd line support from independent Microsoft Exchange specialists, trusted by businesses and MSPs alike for over 20 years.
What we do
At Sembee, we provide expert services in the design, implementation, maintenance, and troubleshooting of Microsoft Exchange environments. Our offerings span Exchange deployments, migrations, and ongoing support, with a particular focus on helping businesses and MSPs optimize their infrastructure. We also step in to rescue failed or substandard installations, ensuring smooth, reliable Exchange operations.
Beyond Exchange, we deliver advanced 3rd line support to MSPs, tackling the complex and high-priority issues that teams might push to the back burner. Our extensive experience with Microsoft technologies enables us to handle critical Office365 configurations, cloud migrations, and networking challenges - whether on an ad hoc or project basis.
The Sembee story
Following our launch in 2003 as a general IT consultancy, we have specialised in Microsoft's Exchange Server since 2006. Today our clients range from small, five-user offices to many thousand-user multi-national organisations. We either work with them directly, or as part of their IT support team.
Technical Mentoring
We provide technical mentoring for staff newly promoted to 3rd line or managerial roles, particularly within MSPs. Our mentoring service is designed to help these individuals shift their focus from hands-on technical work to leadership and delegation, ensuring a smooth transition into their new responsibilities. These sessions can be one-on-one or involve the entire team, depending on the needs of the organization.
Our approach
Because email is such a critical commodity for enterprise-level clients, our policy is to keep our solutions as simple and clean as possible. That way they can be quickly installed, and easily maintained, scaled and upgraded. We never waste a client’s time or money with over-complicated solutions.
We can carry out work on site or remotely. Unlike some other consultancies we never outsource services to third parties.
Whether you are looking for Microsoft Exchange expertise, advanced support, or mentoring for your team, we are here to help you succeed.
