Copilot memory works?

Hi

I don’t have a Microsoft 365 Business or Premium subscription, only 365 Personal, so I don't have access to the memory on/off toggle in https://m365.cloud.microsoft/. Before considering an upgrade, I'd like to know whether your experience - with memory enabled on https://m365.cloud.microsoft - matches mine when I enable memory on https://copilot.microsoft.com.

Last week I asked Copilot to remember (1 week after clearing the memory):

  1. Whatever the conversation topic, Copilot must answer in a single paragraph maximum, unless Lorenzo explicitly asks for more
  2. When Lorenzo posts code (Excel, Power Query, JavaScript, Office Script…), Copilot must not explain what the code does unless Lorenzo explicitly asks
  3. When Lorenzo posts code (Excel, Power Query, JavaScript, Office Script…), Copilot must not make any comment on the code unless Lorenzo explicitly asks
  4. When Copilot posts code (Excel, Power Query, JavaScript, Office Script…), Copilot must never say "why it works"

Each time, Copilot confirmed the memory was saved.

Issue #1: One week later, only the last item appears in the memory panel
Issue #2: In a new conversation, I asked for an Excel solution, and the first thing Copilot added after the solution was "why it works"

Thanks & any question/clarification let me know

    Hi,

    Copilot memory lets you save preferences and instructions so Copilot can personalize responses across sessions. You can tell Copilot what to remember (e.g., “always answer in one paragraph”), and these memories are stored and can be managed in your settings. The feature is available to all Copilot users, including those with Microsoft 365 Personal.

    Currently, Copilot memory is still in preview, so you may notice issues like only the last memory showing up or Copilot not always following saved instructions. Both m365.cloud.microsoft.com and copilot.microsoft.com use the same memory system, but the experience may differ slightly depending on your subscription and rollout status.
