Question details

Users are experiencing issues where Microsoft Copilot stops responding, reports usage limit errors, or unexpectedly loses previous chat records.

Product: Microsoft Copilot
Device & OS: not provided
Scenario: Attempting to use Microsoft Copilot for chat or document summarization but encountering service interruptions.
Observed behavior: Copilot fails to generate responses, displays a message saying it has been used too many times, or clears previous chat history overnight.

Before you start

Verify your internet connection and ensure your Microsoft account is properly synced before troubleshooting service-related errors.

Solution 1Recommended

Wait and Retry During Off-Peak Hours

Allow temporary server loads and usage limits to reset by waiting and accessing the service at a different time.

Microsoft Copilot relies on cloud servers to generate responses. During periods of high traffic, the servers may experience fluctuations, resulting in missing chat history or unresponsiveness. Additionally, if you encounter a 'used too many times' error, you have likely hit a temporary usage cap.

Close the Copilot interface

Completely exit the Microsoft Copilot application or close the browser tab where you are using the service.

Wait for the service to stabilize

Give the system a few hours to process the server load or for your daily usage limits to reset automatically.

Reopen during off-peak times

Try accessing Copilot again later in the day, preferably during off-peak hours, to see if the chat history has been restored and the response feature is working.

Device Independence: These symptoms are almost always related to temporary server issues and are rarely caused by a malfunction on your local device.

Solution 2

Check Microsoft Service Status and Submit Feedback

Verify if there is a known global outage and report persistent missing history to Microsoft Support.

Frequently Asked Questions

Why did my Microsoft Copilot chat history disappear?

Chat history can temporarily disappear due to server synchronization issues, fluctuations, or high service load. In most cases, the history is not permanently deleted and will be restored once the Microsoft servers stabilize.

What does the 'used too many times' error mean in Copilot?

This error message indicates that you have reached the maximum number of prompts or interactions allowed within a specific timeframe. You will need to wait until your usage limit resets before Copilot can respond again.

Is the Copilot not responding issue caused by my computer?

Generally, no. Issues like unresponsiveness, missing chat logs, and usage errors are typically server-side problems caused by high traffic or Microsoft service updates, rather than a hardware or software failure on your local device.
