Error in communication with Kerio Connect with EWS

Hi! I use eM Client 9.1.2109 (9967b93) with my corporate Kerio Connect 9.4.2 (6498). EWS connection works good, but each communication session causes the message in Kerio Error Log:
EWS request GetUserConfiguration: error occurred; code 108, description: Not implemented - only CategoryList configuration is supported., auth user:

Same issue here. Also using latest eM-Client (Windows) and Kerio Connect 9.4.2. (Windows Server 2022).
Is there a fix nearby?

Regards Wilco

If you are gettings errors on the Kerio server, this is something you will need to discuss with Kerio.

The logs you sent don’t show any issues in eM Client.
