Copilot unavailable for other Outlook accounts and Defender won’t activate after Windows repair

Hi sapanpatel,

Thank you for your reply. However, your statement that one account’s Copilot entitlement does not automatically extend to other accounts in New Outlook appears to contradict Microsoft’s own documentation:

https://support.microsoft.com/en-us/outlook/sharing-copilot-in-outlook

Under “Microsoft accounts with a Microsoft 365 Personal, Family, Premium or Pro subscription”, Microsoft explains that signing into Outlook with an eligible subscription account makes Copilot available across the other connected email accounts on the same device, including third-party providers such as Gmail.

I am the Microsoft 365 Family subscription owner. Copilot works for my Microsoft account in New Outlook, but the Copilot button and AI features are unavailable when I switch to my Gmail or IMAP accounts within that same application.

When you suggest verifying the subscription associated with each account, do you mean that I must use my five Family sharing slots to share my subscription with my own additional email addresses? That seems unreasonable, since those slots are intended for sharing with other people, primarily family members. The same documentation also explicitly says that sharing a Family subscription does not give those other people access to Copilot.

Could you clarify how your advice aligns with the functionality Microsoft describes, and whether there is a documented exception relevant to my setup?

Regarding Defender and escalation, Microsoft Support has already reviewed my case history and redirected me here after previous escalation attempts. Asking me to return to the same support route without explaining how to obtain the account-level investigation leaves me in the same loop. If you know a specific route to the team that can investigate these entitlements, please provide it.

Kind regards,
Christer F
