The message alone does not establish a 60-minute session expiry, an attachment-volume cutoff, or permanent loss of the conversation. Recover in small steps, then compare the account, client, conversation, and connection … Read more
Official documentation checked October 14, 2026. If Copilot displays “Content Filtered,” start with the message and the task it blocked. A safety refusal, an organizational data restriction, and a connection failure require different responses.

When you chat with Copilot in Microsoft 365 apps, the assistant may forget what you said a few messages ago. This happens because Copilot has a limited context window that resets after a certain number of turns. The context window is the amount of recent conversation history the model can reference at once.

To roll out organizational Copilot, first decide which capabilities users need, then provision the appropriate entitlement and validate the apps and data they will use.
