Updated October 28, 2025: We have updated the timeline. Thank you for your patience.
Disclaimer: The original message center post was published on August 1, 2025. We previously stated that this is a new feature when it is an expanded capability of the existing feature memory in Copilot. This expanded capability requires new processing of users' data, which is outlined below. We have edited the content below for accuracy and clarity. Thank you to the customers who provided feedback over the past few weeks. We have adjusted our roadmap to address your needs and concerns.
Starting September 1, 2025, Microsoft 365 Copilot will start remembering key highlights from your person-to-person communications in chats, emails, and meetings. Initially these memories will be used to improve the quality of Copilot responses to people-related questions. These memories are private to the user. This feature is available to Copilot-licensed enterprise users.

| 2025-08-30 | MC How Affect | Communication memory uses AI to analyze and summarize digital communications-such as emails, chats, and meeting transcripts-to build a live memory of key highlights. This enables Copilot to deliver more personalized and context-aware responses across Microsoft 365 apps.
Unlike existing personalization features that operate within a single app (e.g., Outlook, Teams Recap, or Facilitator), communication memory provides a unified view across communication channels. Summaries are generated by large language models (LLMs) and may occasionally be inaccurate; each memory includes source links for user review. This feature is on by default for Copilot-licensed users. What you can do to prepare Admins can manage communication memory through the Enhanced Personalization admin control, available via Microsoft Graph. Disabling Enhanced Personalization will turn off all Copilot memory and personalization features across your organization. Compliance considerations Does the change store new customer data, if so, where, and is the data cached or permanently stored? Communication memory stores AI-generated summaries based on user-accessible communications (e.g., emails, chats, meetings). These summaries are stored securely and privately per user in the users' mailbox, for as long as the source data from which the memory was extracted is available. Does the change alter how existing customer data is processed, stored, or accessed (e.g. documents, emails, chats, etc.), if so how and to what extent? Existing communications are processed by large language models (LLMs) to generate summaries that improve Copilot personalization. Does the change introduce or significantly modify AI/ML or agent capabilities that interact with or provide access to customer data, if so summarize changes? Introduces new AI summarization across communication channels using LLMs, expanding personalization beyond single-app contexts. Does the change provide end users any new way of interacting with generative AI, if so how? Users receive personalized Copilot responses based on communication memory, representing a new interaction model with generative AI. Does the change include an admin control and, can it be controlled through Entra ID group membership? Admins can disable Enhanced Personalization (and all Copilot memory features) via Microsoft Graph. Control via Entra ID group membership is supported. Does the change allow a user to enable and disable the feature themselves? Users can view and manage their communication memory, including reviewing linked sources for accuracy. | Copilot builds user memory by using AI to analyze and summarize digital communications-such as emails, chats, and meeting transcripts-to build a live memory of key highlights. This enables Copilot to deliver more personalized and context-aware responses in Copilot chat across Microsoft 365 apps.

Does the change allow a user to enable and disable the feature themselves?Users can view their memories, including reviewing linked sources for accuracy. A user can delete their communication memory only by deleting the original source (message or email). Details on deleting: You can delete a memory by deleting the source item that the memory was generated from - for example, by deleting the email that the memory was generated from. Details on viewing / exporting the memories: Your complete Communication memory can be downloaded through the profile card export. |
