New Outlook: Send via email doesn't work

[mrflory]

With the "new Outlook" sending presentations via email does not work (either throws error message or opens old Outlook).

Possible workaround: Create an eml-file and open it. Also see: https://gist.github.com/jeremykdev/a489d95e628b8217429c53624f225b50

EML File not a solution: Outlook opens it in view mode, not compose. No other option found; also with the help of Claude Opus 4.5.
