Customizing Copilot Agents
Customizing Copilot agents means making AI helpers work for you and your team. You can use templates that are ready to go, or you can build your own agent. Copilot Studio has a dashboard with tools to help you design and change your agents. This part shows what you can do when you customize Copilot agents. You can pick templates, add plugins, and use low-code or pro-code tools.
Using Copilot Studio
Copilot Studio is where you work on Copilot agents. The dashboard has sections like Home Page, Bot Editor, Topics, Entities & Variables, Power Automate Integration, and Analytics. Here is what you do when you make or change an agent:
Look at the dashboard to see all the tools.
Start a new agent by picking a template or making one from scratch.
Give your agent a name and a short description.
Set up the agent’s main instructions, like its persona, tone, and business context.
Change greeting messages and fallback responses to set the right mood.
Use the drag-and-drop editor to build how conversations go and make decision trees.
Decide what makes the agent respond and how it should act.
Use session variables to manage context and memory for personal chats.
Add actions and automations by linking Power Automate flows or APIs.
Pick data sources like Microsoft Graph, SharePoint, or CRM systems.
Test your agent, make changes, and then share it with users.
Tip: Copilot Studio shows analytics so you can see how your agent does and make it better over time.
Templates and Configuration
Templates help you start fast when you customize Copilot agents. You can pick a template that fits your needs or start with a blank agent. Here is what you can set up:
Pick a template from the Create page under Explore agents.
Type a name, description, and instructions for your agent.
Change the agent’s icon to match your brand or project.
Set up data connections and sign in if you need to.
Choose the main language for your agent.
Add extra knowledge sources if you want your agent to answer more questions.
Make the agent and test it to see how it works.
Change the agent’s settings and publish it when you are ready.
You can also change the agent’s name and icon later. Go to the agent’s Overview or Settings page, click Edit, and update the details. For agents in Microsoft Teams, follow the icon rules for best results. You can change how the chat looks by editing HTML files and using JavaScript options like botAvatarImage for the icon or backgroundColor for the chat window.
Note: Use PNG images with transparency for icons. Sizes like 32x32 or 64x64 pixels work best.
Extending with Plugins
Plugins and connectors help your Copilot agent do more things. When you customize Copilot agents, you can add tools that connect to other systems and services. Here are some common plugins:
Prebuilt connectors to popular APIs (like Microsoft Graph or SharePoint)
Custom connectors for your own services
REST API connections for web services
Prompts for single-turn questions
Model Context Protocol (MCP) tools
Computer use (preview) agents that work with websites and desktop apps
These plugins help your agent send emails, check the weather, read or write data in Dataverse, or post messages to Teams. You can add and set up these tools in Copilot Studio to make your agent more helpful.
Integrations with tools like Azure AI Foundry and Power Automate make customizing Copilot agents even better. Azure AI Foundry lets you build custom AI models and knowledge sources. You can share these through Azure Functions. Power Automate helps you make flows that connect these functions to your agent. This way, your agent can use custom AI logic and give answers right away. You can share these agents to Microsoft 365 Copilot and Teams, so users can use them in apps they know.
Low-Code and Pro-Code Options
You can pick low-code or pro-code ways when you customize Copilot agents. Low-code uses tools like Copilot Studio, Power Platform connectors, and plugins. These help you build agents fast and connect to Microsoft 365 apps. Pro-code uses tools like Teams Toolkit in Visual Studio Code. You get full control, can add custom AI models, and make advanced workflows. Pro-code agents can work in Teams, web, and other apps, and support harder jobs.
Tip: Many teams use both low-code and pro-code ways to get speed and flexibility.
Customizing Copilot agents lets you make AI helpers that fit your needs. You can start simple and add more features as you learn, using the tools and methods that work for you.
Integration and Automation
Connecting to Data Sources
Copilot agents can link to many data sources. This helps your agent find answers fast. You use built-in connectors for tools like Azure DevOps, Confluence, Google Drive, Jira, GitHub, and ServiceNow. Each connector uses a scoping attribute to focus on key data. For example, you can set Azure DevOps to an area path. You can set Google Drive to a folder. This makes answers more exact.
You should use Microsoft Graph Connectors for outside sources like SQL databases, ticketing systems, and wikis. Admins need to turn on and set up these connectors in the Microsoft 365 admin center. Only connect trusted sources. You can make custom connectors for your own systems with APIs. Always scope data to certain projects or folders to keep it useful. Refresh connections if something does not work.
Tip: Pick knowledge sources instead of general sources. This helps your agent give better answers.
Security is important when you connect to private data. You must keep outside data inside the app. Do not let Copilot use it for training. Use trusted APIs and knowledge sources only. Give Copilot just the permissions it needs. Admins should approve all connectors. Use Microsoft 365 access controls to limit who sees the data. Watch agent activity and label private data. Encrypt data and follow rules like GDPR and HIPAA.
Automating Workflows
Copilot agents help you automate many jobs. You can set up agents to do code generation, testing, and project management. This lets you spend time on harder problems. Agents suggest code snippets and write code for you. They test code and find bugs. You can use agents to manage tickets, update CRM entries, and send reports.
Here are some real-world examples:
Automate approval workflows for invoices using Power Automate.
Make data analysis and reporting easier in Excel.
Answer customer support tickets, follow up, and send cases higher.
Study sales data, pick leads, and send messages.
Collect data from Power BI and make reports.
Watch inventory and order supplies.
You can use Copilot Studio to build agents that start workflows, approvals, and data processing. Agents talk with users, answer questions, and start flows without help. This saves time and stops mistakes.
Note: Good tips include finding tasks to automate, testing agents, and watching results. Agents get better as you use them.
Considerations and Challenges
Privacy and Compliance
When you use Copilot agents at work, you must follow privacy rules. There are many laws like GDPR, CPRA, and HIPAA. You need to:
Do Privacy Impact Assessments (PIA) and Data Protection Impact Assessments (DPIA). These help you find and lower privacy risks.
Use least-privilege access. This means Copilot agents only see what they need.
Keep Records of Processing Activities (ROPA) to track how data is used.
Classify and label data. This helps you manage sensitive information and avoid problems.
Set up strong access controls and watch agent activity. This helps stop data leaks.
Copilot Studio helps you follow rules like GDPR, HIPAA, ISO 27001, and SOC 2. You get tools like Microsoft Purview Audit Logs and Power Platform Admin Center. Data Loss Prevention (DLP) policies and sensitivity labels help keep your data safe. Role-Based Access Control (RBAC) and tenant-bound execution keep data separate and secure.
Microsoft Copilot Studio also meets standards like HITRUST and FedRAMP. It uses encryption to protect data when stored or sent. You control user consent, and users can ask to delete their data. Plugins are managed carefully, and you choose which ones to use.
Limitations and Pitfalls
You may have some problems when using Copilot agents. Here are some common issues:
Many companies use different environments for development, testing, and production. You should use environment variables in each place to manage secrets and settings. Automated deployment helps keep things the same and safe.
It can be hard to track how agents are used or move them when someone leaves. Reports may not show everything you need. To avoid these problems, set up good rules, watch usage, and teach your team best practices.
Customizing Copilot agents helps you and your team work better. You can make tasks easier and get more done with quick setup and simple tools.
Start by picking templates, making your own topics, and trying out agents in Copilot Studio.
