Calender entries in Exchange

[Sebastian Gödecke]

Hi,
i'm using
Kontact: 6.4.2 (25.04.2)
KDE Frameworks: 6.15.0
Qt: 6.9.1 wird verwendet und gebaut wurde mit 6.9.1
Manjaro Linux (Xcb)
Build ABI: x86_64-little_endian-lp64
Kernel: linux 6.15.3-1-MANJARO

and connected it with "ews" to our exchange server.
I think the most is working very fine, but my calender entries i'm
adding in Calender weren't stored in Exchange, they were always saved
in my personal calender. i can't switch to my "akonadi_ews_resource_9"
(which is my Exchange connection)
Is there a hint how to use this Exchange?
Regards Sebastian
