Case Study: Plante Moran achieves doubled intranet usage, 50% faster findability, and $600,000 annual savings with Office 365

Accounting Firm Revolutionizes Collaboration with Cloud File-Sharing and Social Tools

Plante Moran, a 2,500‑person U.S. accounting and advisory firm, needed to modernize aging on‑premises intranet and client collaboration sites to support an ambitious growth strategy, improve mobile and remote access, and reduce administrative overhead. Their legacy SharePoint environment was inflexible, slow to provision, and hindered access to expertise and content across offices and time zones.

Working with Rightpoint and Microsoft FastTrack, Plante Moran migrated to Microsoft 365—using SharePoint Online, OneDrive for Business and Yammer—to create the KnowledgeShare intranet and a cloud‑based Collaboration Center. The change doubled daily intranet users, cut search time for content and experts by 50%, increased client engagement sites to 12,600 (holding 4.2M+ files), reduced provisioning to under an hour, enabled 24/7 mobile access, and saved about USD 600,000 annually while freeing IT to focus on new features.
