MS Teams Collaboration
End Teams sprawl. Naming policy, creation rules, sensitivity labels, and lifecycle — pragmatic, enforced, documented.
Three Years of Teams, Four Hundred Orphaned Channels
Teams was turned on. Everyone was told to use it. Three years later: hundreds of teams, half of them active, the other half with a single owner who left the company. Files are scattered across “Team A – Projects,” “Team A – Projekte 2023,” and “Copy of Team A.” External guests sit in teams nobody audits. Sensitive data lives next to lunch menus.
This is not a failure of your IT team. Teams governance is not one switch — it is a combination of a naming policy in Microsoft Entra ID, sensitivity labels in Microsoft Purview, group-creation restrictions, expiration policies, and a lifecycle process that someone actually owns. Without structure, every new feature adds more sprawl.
Traditional consulting for a governance rollout? Two months, five figures of governance documents nobody reads. The consultant leaves. The sprawl continues.
ACTIVITIES IN DETAIL
DELIVERABLES
Inventory the current Teams landscape: active vs. inactive, orphaned owners, external guests, naming patterns, sensitive-data exposure
Define creation policy: who can create teams (all users vs. designated group), approval workflow if needed
Configure a Microsoft Entra ID naming policy: prefix, suffix, blocked words — applied to all new Microsoft 365 Groups
Design and publish sensitivity labels via Microsoft Purview: Public, Internal, Confidential, Strictly Confidential — with linked privacy, guest-access, and external-sharing controls per label
Configure group expiration policy: lifetime (6–12 months), renewal rules, notification schedule (Entra ID P1 required)
Define the Teams app baseline: allowed apps, blocked apps, default app layout, approval process for new apps
Teams messaging policies per user segment: chat, channel posting, formatting, meeting recording defaults
Decision framework: private channel vs. standard channel vs. new team — one-page matrix for end users
Rename and reclassify top-100 existing teams to match the new policy — pilot and template for the rest
Orphaned-team remediation: reassign owners, archive inactive teams (read-only), delete obsolete ones with owner sign-off
End-user communication: what changes, why, what they need to do, who to ask
