Hello, just found this https://github.com/KrissN/akonadi-ews
Seems to work nicely for now, let's see if it eleminates my problem of imap downloading all my emails several times per week (~4GB mailbox in total). Package is easily made with dh_make and adding --with kde to debian/rules Build deps seems to be extra-cmake-modules, libkf5libkdepim-dev, libkf5akonadimime-dev, libkf5calendarcore-dev, libkf5mime-dev Libor
