Microsoft Strategy: 2026 Considerations for Cloud Pbx System

EPC Group has a heritage since 1997 in Microsoft consulting. This experience is crucial because current 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 have a structural advantage in enterprise Microsoft migrations.

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 held the Microsoft Gold Partner status from 2000 to 2022, when the program retired. We now have the core Solutions Partner designations.

This designation is often used by Microsoft field teams for:

  • Vet enterprise Customer 0 nominations
  • Named-account engagements
