Co-Pilot in Outlook

Hello Microsoft Support,

I have an active Microsoft 365 subscription with Copilot. Copilot is working successfully in Word and PowerPoint on my Mac using the same Microsoft account.

However, in Outlook for Mac (version 16.110.2), Copilot displays the message:

"Copilot is not supported for the account <email address>"

My BTInternet email account is configured in Outlook as an IMAP account. This is also the email address associated with the Microsoft account I use to sign in to Microsoft 365.

I have verified that Word and Outlook show the same signed-in Microsoft account.

I reviewed Microsoft documentation indicating that Copilot access in Outlook can be be shared across connected email accounts, including certain third-party providers, when using an eligible Copilot subscription. Because of this, I would like clarification on why Copilot is unavailable for my BTInternet account and whether there is a configuration, licensing, or provisioning issue affecting my account.

Could you please investigate and advise on the steps required to enable Copilot in Outlook for this account?

Thank you for your assistance.

Kind regards,

Steve Bowen
