Question details

Users are experiencing severe lag and unresponsiveness when using Microsoft 365 Copilot and Copilot Chat in Word, with text generating as slowly as one word every few seconds despite working normally the previous day.

Product: Microsoft Word (Microsoft 365 Copilot)
Device & OS: not provided
Scenario: Generating text or using the Copilot Chat sidebar within Microsoft Word.
Observed behavior: Copilot suddenly becomes extremely slow, outputting responses at a rate of one word at a time, rendering the AI assistant virtually unusable.

Before you start

Before troubleshooting, ensure your internet connection is stable and try restarting Microsoft Word, as temporary network interruptions can sometimes cause delayed cloud AI responses.

Solution 1Recommended

Check Microsoft 365 Service Health Status

Verify if a Microsoft backend service outage or degradation is causing the Copilot performance issues.

Because Copilot relies entirely on Microsoft's cloud servers to process and generate text, regional server issues (such as those observed in Australia) can cause severe latency. Checking the admin center will confirm if this is a known issue (e.g., incident CP995690) that Microsoft is already working to resolve.

Access the Admin Center

Open your web browser, navigate to the Microsoft 365 admin center, and log in with your administrator credentials.

Navigate to Service Health

On the left-hand navigation menu, click on 'Health' and then select 'Service health'.

Review Active Incidents

Look through the list of active advisories and incidents for any mentions of Microsoft 365 Copilot or Microsoft Word to see if there is an ongoing degradation.

Admin Access Required: You will need administrator privileges to view the Service health dashboard. If you are a standard user, you will need to ask your IT department to check this for you.

Solution 2

Submit Feedback via the Microsoft Portal

If the service health page shows that the system is fully operational but Copilot remains slow, report the specific latency issue directly to Microsoft.

Frequently Asked Questions

Why is Microsoft Word Copilot typing one word at a time?

This slow response rate is typically caused by Microsoft backend service degradations or regional server outages, which restrict the speed at which the cloud AI can send generated text back to your local application.

Does reinstalling Microsoft Word fix the Copilot lag?

Generally, no. Because Microsoft 365 Copilot processes requests on cloud servers rather than on your local machine, unresponsiveness usually resolves only when Microsoft restores normal service health.

How do I know if Microsoft Copilot is down in my region?

Your organization's IT administrator can check the Microsoft 365 admin center's Service health dashboard. Active advisories will display real-time updates regarding service delays in specific regions.

Does this latency affect Copilot Chat as well?

Yes, server-side service degradations that slow down in-line text generation in Word typically affect the Copilot Chat sidebar equally, resulting in the same delayed, word-by-word output.
