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.
