Microsoft Teams has evolved significantly since its launch, and by 2026, it remains the cornerstone of workplace collaboration for organisations across the UK and beyond. If you're responsible for managing Teams in your organisation, you're juggling quite a bit. User onboarding, security policies, meeting controls, and compliance requirements all fall under your remit. This guide walks you through the essentials of Teams administration in 2026, so you can manage your environment confidently and keep your organisation secure.
According to recent industry data, organisations using Microsoft Teams saw a 34% improvement in employee collaboration metrics throughout 2025 and into 2026. However, this success depends entirely on solid administration practices. Without proper Teams administration, you risk security vulnerabilities, compliance issues, and frustrated users.
The role of Teams administrator has become increasingly specialised. In fact, organisations are now investing more in dedicated Teams administration roles, with IT professionals in this space earning between GBP 38,000 and GBP 52,000 annually in the UK (2026 figures). The demand for skilled Teams administrators continues to grow, making it a valuable skill to develop.
Before diving into the technical side, let's clarify what you're actually responsible for as a Teams administrator.
The Teams admin centre is your command centre. You'll spend most of your time here managing:
Your primary goal is straightforward: ensure Teams works smoothly whilst maintaining security and compliance standards.
Teams policies control what users can and cannot do within the platform. By 2026, Microsoft has streamlined policy management significantly, but you still need to understand the key areas.
Meeting Policies are critical. These determine who can schedule meetings, whether participants can unmute themselves, and whether meetings can be recorded. If you're managing a regulated industry (financial services, healthcare), these settings directly impact your compliance position. We recommend setting different meeting policies for different user groups. For instance, customer-facing teams might have stricter recording policies than internal departments.
Messaging Policies control user behaviour in chats and channels. You can prevent users from deleting messages, editing messages after a certain time period, or using specific chat features. In 2026, organisations are particularly focused on preventing accidental external data sharing, so consider restricting external chat access for sensitive departments.
Teams Creation Policies let you control who can create teams. Many organisations now restrict team creation to specific roles, then require a naming convention (for example, "DEPT-ProjectName"). This prevents the sprawl of redundant teams and makes governance easier.
Guest access is one of the most complex areas of Teams administration. By 2026, hybrid and distributed teams mean you're almost certainly inviting external people into your Teams environment.
Here's what you need to know: guest access is turned off by default in most organisations, but you'll likely need to enable it. When you do, implement these controls:
Many organisations use a "guest access request" process in 2026, where users request guest access through their IT team rather than adding guests ad hoc. This adds friction, yes, but it significantly reduces security incidents.
One area Teams administrators often overlook is user lifecycle management. This includes offboarding, which has become critical post-pandemic.
When someone leaves your organisation, you need to:
Set up a process with your HR and IT teams. By 2026, many organisations automate this using Azure AD dynamic groups, which automatically remove users from Teams based on their employment status. This prevents orphaned teams and reduces manual work.
If your organisation is regulated (and which UK organisation isn't these days?), Teams compliance is non-negotiable. Message retention policies determine how long Teams messages are kept before deletion. By default, messages are kept indefinitely, but depending on your industry, you might need to set specific retention periods.
eDiscovery in Teams lets you search for specific messages across channels and chats for legal holds or investigations. It's genuinely important to test your eDiscovery setup before you need it in a crisis. Many organisations discover their eDiscovery isn't working properly only when they're facing a compliance investigation.
The Teams app ecosystem has exploded. By 2026, thousands of third-party apps integrate with Teams, from project management tools to customer relationship platforms. Your role includes managing which apps users can access.
Disable apps that pose security risks or aren't used. Configure app permission policies so sensitive apps (like HR systems) are only available to specific user groups. Review your app list quarterly and remove unused applications. This reduces security surface area and keeps the Teams experience cleaner for your users.
Teams administration isn't a "set and forget" activity. Use the Teams analytics dashboard to understand adoption, meeting usage, and channel activity. If adoption is low in certain departments, that's valuable intelligence for leadership.
Monitor Teams health regularly. By 2026, Microsoft provides detailed health dashboards showing service status, device health, and network performance. Familiarise yourself with these tools.
