Microsoft Teams adoption has exploded in recent years — but with that adoption comes a common problem: Teams sprawl. Without a governance framework in place, organizations end up with hundreds of abandoned Teams, inconsistent naming conventions, security gaps, and frustrated users who can’t find anything.
This post outlines the essential components of a Microsoft Teams governance strategy.
What is Teams Sprawl?
Teams sprawl occurs when:
- Users create Teams for every project, meeting, or conversation
- Teams are never archived or deleted when projects end
- There are no naming conventions, so Teams can’t be found easily
- Sensitive information is shared in teams with overly broad membership
- Guest access is enabled without proper controls
Left unchecked, a 100-person organization can end up with 500+ Teams within a year.
1. Define a Teams Creation Policy
The first step is deciding who can create Teams and under what circumstances.
Options:
- Unrestricted — Anyone can create a Team (the default, and usually problematic)
- Restricted — Only specific groups (e.g., managers, department heads) can create Teams
- Request-based — Users request a Team through an approval workflow
For most organizations, a request-based or semi-restricted approach works best. You maintain control without becoming a bottleneck.
In Microsoft 365, you can restrict Team creation through Azure Active Directory group settings.
2. Establish Naming Conventions
Consistent naming makes Teams findable and reveals their purpose at a glance. A simple naming convention might look like:
[Department]-[Project/Purpose]-[Year]
Examples:
- IT-MigrationProject-2025
- HR-Onboarding-General
- Sales-ClientABC-2025
You can enforce naming policies through Azure AD’s Group Naming Policy feature, which can also add prefixes/suffixes automatically.
3. Set Up Team Lifecycle Management
All Teams should have a defined lifecycle — from creation to archival or deletion. Microsoft 365 Groups expiration policies can help automate this.
Key lifecycle components:
- Expiration policies — Teams auto-expire after a set period unless renewed
- Renewal notifications — Owners are reminded to renew or let Teams expire
- Archival process — Clear steps for archiving completed project Teams
- Deletion criteria — When and how inactive Teams get deleted
This is especially important for project-based Teams that serve a time-limited purpose.
4. Control Guest Access
Guest access in Teams allows external users to participate in channels and chats — which is incredibly useful, but requires careful governance.
Best practices:
- Enable guest access at the tenant level but configure it thoughtfully
- Require approval before guests can join sensitive Teams
- Set guest expiration — automatically remove guests who no longer need access
- Use Azure AD Entitlement Management for more sophisticated access governance
- Regularly audit Teams with guest members
5. Manage Channel and Tab Usage
Within each Team, channels and tabs can multiply quickly. Consider:
- Standard channels for ongoing topics (General, Announcements, etc.)
- Private channels for sensitive discussions requiring restricted membership
- Clear guidelines on which apps/tabs can be added
6. Implement a Governance Policy Document
Beyond technical controls, your Teams governance needs to be documented and communicated. A governance policy should cover:
- Who can create Teams and how
- Naming conventions
- Membership and access guidelines
- What information can/cannot be shared in Teams
- Guest access rules
- Archival and deletion procedures
Getting Your Teams Governance Right
Implementing Teams governance after sprawl has already set in is significantly harder than establishing it from the start. If your organization is just beginning your Teams journey — or if you’re trying to clean up an existing environment — a proper governance framework is essential.
