How to Remove Third-Party External Agents from the Copilot Agent Store

If you're starting to roll out Microsoft Copilot in your organization, you're probably exploring the Agent Store. But you might also be noticing something unexpected—third-party agents like Jira, Monday, or Dropbox showing up without your approval.

You're not alone. Many IT admins are seeing this and asking:
"Where did these agents come from, and how do I remove them?"

Here’s how to clean up your Copilot Agent Store and give your users a more curated, secure experience:

Why This Matters

• User confusion: Users see unfamiliar agents and start submitting tickets.
• Security concerns: Third-party agents may access data you haven’t vetted.
• Control: You want to manage what’s available in your environment.

Steps to Remove Third-Party Agents

1. Go to the Microsoft 365 Admin Center
   • Navigate to the Copilot section in the left-hand menu.
2. Open Copilot Settings
   • Under the Copilot dropdown, select Settings.
3. Go to the Data Access Tab
   • This is where you control agent visibility and access.
4. Adjust Agent Permissions
   • Find the setting:
     “Allow apps and agents created by external publishers”
     • Uncheck this box to remove third-party agents from the store.
5. Optional: Fine-Tune Access
   • You can also:
     • Allow or block Microsoft-created agents.
     • Allow only agents created by your organization.
     • Assign access to specific security groups.
6. Review Agent Types
   • In the Agents section, check the Type column:
     • External = third-party
     • Microsoft = first-party
     • Shared = created by users in the Copilot web app
     • Custom = built in Copilot Studio or M365 toolkit
7. Refresh the Agent Store
   • Go back to Copilot, refresh the page, and you’ll see the third-party agents disappear.
