Microsoft Strategy: 2026 Considerations for Business Pbx System
Microsoft Solutions Partner status includes six designations: Data & AI, Modern Work, Infrastructure, Security, Digital & App Innovation, and Business Applications. This status replaced the Microsoft Gold Partner program in 2022.
EPC Group maintained the longest continuous Microsoft Gold Partner status in North America from 2000 to 2022. We now hold the core Solutions Partner designations.
Microsoft field teams often use these designations to evaluate enterprise Customer 0 nominations and named-account engagements.
EPC Group has a history since 1997 in Microsoft consulting. This experience is crucial because today's Microsoft platform decisions build on 25 years of architectural choices. For example:
- Active Directory schema decisions from 2005 impact Microsoft Entra ID Conditional Access policy design in 2026.
- SharePoint 2003 information architecture decisions affect Copilot grounding quality in 2026.
Firms that can navigate this complexity are rare. Fewer than a dozen Microsoft Solutions Partners in North America have a structural advantage in enterprise Microsoft migrations.
Decision factors EPC Group evaluates
- Vendor consolidation analysis
- Compliance and governance posture review
- Enterprise architecture roadmap
- Cost optimization and licensing audit
- Microsoft platform capability assessment
