Microsoft Teams has become the default collaboration platform for businesses of all sizes — and IT agencies are frequently called upon to deploy, configure, and support it for their clients. A well-structured setup process makes the difference between a smooth rollout and weeks of support tickets.
This checklist covers everything you need to deploy Microsoft Teams successfully for a client organisation.
Phase 1: Pre-Deployment Planning
Licensing
- Confirm Microsoft 365 licensing tier (Teams is included in Business Basic, Business Standard, Business Premium, and Enterprise plans)
- Identify users who need Phone System add-on for calling features
- Confirm guest access requirements and licensing implications
Network Assessment
- Run the Microsoft Teams Network Assessment Tool
- Check bandwidth requirements (1.5 Mbps per user for HD video)
- Verify QoS (Quality of Service) configuration on network equipment
- Check firewall rules — Teams requires specific ports and URLs to be whitelisted
- Test from all office locations and for remote workers
Identity and Directory
- Confirm Azure Active Directory (Entra ID) is configured correctly
- Verify all users have Microsoft 365 accounts with correct licences assigned
- Plan for guest users (external collaborators)
- Configure Multi-Factor Authentication (MFA) — mandatory for security
Phase 2: Core Configuration
Teams and Channels Structure
- Design the Teams and Channels structure with the client (don't let users create ad-hoc)
- Create a naming convention for Teams (e.g., [Department]-[Project])
- Configure Teams creation policies — restrict to IT admins or specific roles
- Set up standard channels for each Team (General, Announcements, etc.)
Messaging Policies
- Configure messaging policies (who can delete messages, use GIFs, etc.)
- Set up priority notifications for urgent communications
- Configure read receipts policy
Meeting Policies
- Configure meeting policies (recording, transcription, lobby settings)
- Set up meeting room devices if applicable
- Configure live events settings if needed
- Set default meeting options (who can bypass lobby, who can present)
Security first: The most common Teams security mistakes are allowing external access without proper controls, not enabling MFA, and not configuring data loss prevention (DLP) policies. Address these before go-live.
Phase 3: Security and Compliance
- Configure Conditional Access policies in Azure AD
- Enable Microsoft Defender for Office 365 (if licensed)
- Configure Data Loss Prevention (DLP) policies for sensitive data
- Set up retention policies for Teams messages and files
- Configure eDiscovery settings if required for compliance
- Review and configure external access and guest access settings
- Enable audit logging in the Microsoft 365 compliance centre
Phase 4: Integration and Apps
- Configure SharePoint integration (Teams files are stored in SharePoint)
- Set up OneDrive integration for personal file storage
- Install and configure approved third-party apps (Planner, Forms, Power BI)
- Configure Teams Phone if applicable (Direct Routing or Calling Plans)
- Set up Power Automate workflows for common processes
Phase 5: User Adoption
- Create user training materials (quick start guides, video tutorials)
- Identify and train Teams Champions in each department
- Run a pilot with a small group before full rollout
- Communicate the rollout plan to all users in advance
- Set up a dedicated Teams channel for Teams support questions
- Schedule follow-up training sessions 2–4 weeks after go-live
Phase 6: Post-Deployment
- Monitor Teams usage analytics in the Microsoft 365 admin centre
- Review and clean up unused Teams and channels after 30 days
- Conduct a 30-day post-deployment review with the client
- Set up ongoing governance processes (Teams lifecycle management)
- Schedule quarterly security reviews
