Between channels nobody uses, duplicate workspaces, conversations scattered everywhere, and files that seem to have vanished into thin air, Microsoft Teams can get a little unruly. 

And the bigger your business gets, the bigger the mess can become. 

The good news? A little structure and regular maintenance can go a long way toward keeping Teams organized, secure, and easy to use. The trick is knowing what to look for, what to clean up, and how to keep things from getting out of hand in the first place. 

Here are six ways to get things back under control. 

1. Not Everything Needs Its Own Team 

It’s easy to create a new team whenever a project starts or a department needs to collaborate. But before you know it, you’ve got dozens of workspaces, some doing practically the same thing. 

Before creating another team or channel, ask yourself: 

• Does a space for this work already exist? 

• Could we use an existing channel instead? 

• Is this an ongoing project or just a short-term conversation? 

The goal isn’t to make collaboration harder. It’s to keep everyone from having to search through six different places to find the same information. 

2. Give Things Names People Can Actually Understand 

If your Teams environment includes “Project Updates,” “New Project Updates,” and “Project Updates FINAL,” it’s probably time for a naming convention. 

A consistent naming system helps employees find what they need without playing detective. 

Consider organizing teams by department, client, or major project. Then use channels for specific topics within those groups. 

For example, your Marketing team might have channels for Campaigns, Content Planning, and Events. 

Whatever system you choose, make sure everyone understands it and uses it. 

3. Let Completed Projects Retire 

That project you wrapped up two years ago? It probably doesn’t need to be sitting alongside your active work. 

Microsoft Teams allows you to archive inactive teams, preserving their conversations and files for reference while taking them out of everyday use. 

Make a habit of reviewing your Teams environment periodically. Look for completed projects, inactive workspaces, and channels that have outlived their usefulness. 

And before you start deleting things, remember that your business may have data retention requirements. Archiving is often a better first step. 

Think of it as cleaning off your desk without throwing away the filing cabinet. 

4. Don’t Forget What’s Behind the Files 

Ever wonder where all those files you upload to Microsoft Teams actually go? 

Behind the scenes, Microsoft Teams uses SharePoint to store files shared in channels. Each team has an associated SharePoint site, and standard channels have folders within its document library. Private and shared channels have separate SharePoint sites. 

That means keeping Teams organized isn’t just about cleaning up conversations. It’s also about managing the documents, folders, and permissions behind them. 

A few things worth paying attention to: 

• File organization: Use consistent folder structures and file names so employees can find documents without digging through endless folders. 

• Duplicate files: Avoid uploading multiple copies of the same document across different channels. Sharing a link to the original can help everyone work from the same version. 

• Permissions: Understand who can access files through Teams and SharePoint, especially when sharing documents outside your organization. 

• Document libraries: Make sure your SharePoint libraries have a clear purpose and aren’t becoming dumping grounds for files nobody can find. 

• Version history: Use SharePoint’s version history to track changes and recover earlier versions instead of creating files named “Final,” “Final2,” and “FINAL-ActuallyFinal.” 

One thing to keep in mind: moving, renaming, or deleting files and folders can affect links and workflows that employees rely on. A little planning before reorganizing your SharePoint environment can prevent unnecessary headaches. 

A clean Teams environment is only half the equation. The files behind it need attention, too. 

5. Know Who Still Has the Keys 

Here’s where a little housekeeping becomes a cybersecurity conversation. 

Employees change roles. Vendors finish projects. Outside partners come and go. But the access you’ve given them in Microsoft Teams doesn’t always get cleaned up along the way. 

That can leave people with access to information they no longer need. 

Take a look at: 

• Guest access: Do outside vendors and partners still need access? 

• Team membership: Are the right employees in the right spaces? 

• File sharing: Are documents accessible only to the intended people? 

• Ownership: Is someone responsible for reviewing permissions? 

And remember, access isn’t limited to Teams membership. SharePoint sharing links and permissions may also grant access to files, so both need attention. 

Keeping access current is an important part of protecting your business information. 

If you’re unsure who can access what, your IT provider can help review your Microsoft 365 permissions and identify potential gaps. 

6. Someone Has to Own It 

You can have the best organizational guidelines in the world, but they won’t do much good if nobody follows them. 

Keeping Microsoft Teams organized isn’t a one-time project. As employees join, responsibilities change, and new projects begin, your Teams environment needs ongoing attention. 

That means having someone responsible for reviewing inactive workspaces, managing permissions, maintaining naming conventions, and making sure new teams are created with a purpose. 

Whether that responsibility falls to your internal IT department or a managed IT partner like InfiNet Solutions, the important thing is that someone owns it. 

After all, your employees have enough to manage without adding Microsoft Teams maintenance to their to-do lists. 

Your Team Has Better Things to Do Than Manage Teams 

Microsoft Teams should make collaboration easier, not create another job for your employees. 

You don’t need a perfect system. You need a practical one. Clear naming conventions, sensible access controls, organized SharePoint libraries, regular cleanup, and defined ownership can go a long way toward making Teams easier to use. 

And as your business grows, having those practices in place becomes even more valuable. 

At InfiNet Solutions, we help businesses make technology work for their people, not the other way around. Whether you need help organizing your Microsoft 365 environment, managing access, or improving how your team collaborates, we’re here to help. 

You’ve got a team to run. Let us help you manage Teams. 

Frequently Asked Questions 

How many teams should my business have in Microsoft Teams? 

There’s no perfect number. It depends on how your business operates. Each team should have a clear purpose, and you should avoid creating multiple workspaces for the same work. 

Should I delete old Microsoft Teams channels? 

Not automatically. Microsoft Teams supports archiving entire teams, which preserves their content for reference. Individual channels have different management options. Before deleting anything, consider whether the information is still needed and review your retention requirements. 

Where are files stored in Microsoft Teams? 

Files shared in Teams channels are stored in SharePoint. Standard channels use folders within the team’s SharePoint document library, while private and shared channels have separate SharePoint sites. Files shared in one-on-one or group chats are generally stored in the sender’s OneDrive. 

Can a messy Microsoft Teams environment create security risks? 

Yes. Outdated guest access, unnecessary team memberships, and overly broad file-sharing permissions can leave information accessible to people who no longer need it. Regular access reviews help reduce that risk. 

How often should we review our Microsoft Teams environment? 

There’s no one-size-fits-all schedule. A comprehensive organizational review once a year may be sufficient for some businesses, provided routine maintenance happens throughout the year. Access permissions, especially for external users or sensitive information, may need more frequent attention. Microsoft and NIST both emphasize establishing review practices that reflect your organization’s needs and security risks. 

Who should be responsible for managing Microsoft Teams? 

Your internal IT team, a designated administrator, or a managed IT provider can help oversee the environment. The important thing is assigning clear responsibility for maintenance, permissions, and organizational standards.
