Is it possible to add the function of disabling the forced jump from "Mail and Calendar" to "Outlook New"?

One method is to install older version of "Mail and Calendar". E. g. version 16005.14326.21422.0. This old version doesn't have the forwarding to outlook and works just fine.

To do this, go to: https://store.rg-adguard.net/
And Search for: https://apps.microsoft.com/detail/9wzdncrfhvqm

There you can download the necessary files.
To install AppX you probably have to activate Developer Mode in Windows settings etc. So, your mileage might vary.

PS: Also Reinstall means, you probably have to redownload all your e-mails. (But accounts are saved directly in windows, so no problem there.)
PPS: Another important thing is, to deactivate automatic updates in Microsoft Store, otherwise you end up with the new, not working version, again.
