Copilot options are disabled on Mac

I have a Copilot Business and also a Business Standard licences that give me access to desktop apps and copilot on them.

I Word it works fine, but on Outlook the Copilot button (top-right select box) shows options like Coaching, Draft and Settings disabled, when in a new message.

When replying, the same button shows Reply and Summarize disabled, but Chat and Settings enabled.

On the web version everything works.

I have already updated to the latest versions and made a check license to make sure all features are ok.

What can be missing here?

Thanks.
