[Users] How to Import+Export eMail messages in MSG format?

[Ben Stover]

Assume I want to migrate an account from Outlook to Clawsmail.

Therefore I need a function/menu to import an existing MSG email tree.

In addition I want to have the option switch back later to Outlook. So I need an MSG export function/menu as well.

How can I achieve this?

Is there a plugin?

Can import/export MSG menu be added to to Claws Mail?

Thank you
Ben
