You can’t afford downtime during a migration

Support ended October 14, 2025. We move you to Exchange Online, or to Exchange Server Subscription Edition where a server has to stay.

Six areas of expertise, one team
Guardrails first, then Copilot set up and adopted with a champions community, and AI solutions and automations that give people real time back. When fixing the process beats adding AI, we say so.
Email, files, phones, and devices moved to Microsoft’s cloud in waves, with a pilot group first and a way back at each step.
Know where you stand across Microsoft 365, then fix it in order, from identity and devices to email and data, using the Microsoft security tools you already license.
Move what should move to Azure, run what stays on-premises the same way, and prove recovery before you need it. Each workload gets its own answer on cost, risk, and dependencies.
Calls answered at any hour, systems watched and patched, and backups tested, with a report each month. The biggest risks get fixed first, then steady state.
Apps and automations that replace spreadsheets and email chains. We build them on Power Platform or custom code with the security you already have, connected from the start to your sign-ins and SharePoint.
Copilot adoption from 4% to 50%+, tracked on a live dashboard
Written rules for who may use AI, on what data, and with whose approval come first, with controls that enforce them. Then we set up Copilot and drive adoption with a champions community. Agents and automations take on repetitive work, with a person approving what goes out, and this dashboard shows what is actually used.
Questions we get
Why choose Preeminent Solutions over a larger partner or a local provider?
Because we operate without a dedicated sales team. Each customer relationship and project receives direct oversight from one of our company principals, and we only take on work we’re confident we can do well.
Where are you located, and who do you serve?
We’re based in New York and work with organizations there and across the United States. Most of our clients are mid-size and enterprise organizations in higher education, state and local government, utilities, and financial services, along with large companies in other sectors.
Are you a Microsoft partner? Do you only work with Microsoft?
We’re a Microsoft Solutions Partner in the Microsoft AI Cloud Partner Program, and Microsoft is where we go deepest. We’re Microsoft-first, not Microsoft-only: we also work with Google, Amazon Web Services, Apple, Dell, Cisco, VMware by Broadcom, Nutanix, NetApp, Quest, Veeam, and Nerdio. Our projects have integrated tools such as Okta, ShareGate, and ServiceNow.
How big are the projects you take on?
Anywhere from a single department’s assessment to multi-year programs across 20,000+ devices. We size the team to the work.
How do we start?
Request a meeting or call (516) 240-8079. One of our company principals replies within one business day.
