Problem with Kopano Core or some of the stores

kg

Hello,
as you can read in this topic in the Z-Push Section Z-Push: StatusException, I have the problem that some of my devices cannot sync emails (anymore), because of an Exception that is thrown in Z-Push due to an Error returned from the mapi_exportchanges_config function.
@Manfred already looked at the wbxml log and outputs from z-push-admin and z-push-top, and suggested to enable the ICS Log in KC to be able to debug what is going on. I did so, but I’m not sure what to look for in this very verbose log output.

Excerpt from the Log:

The assumption is that something is wrong with the affected stores, but I have no idea on how to debug this.
I would really appreciate some help on this one.

Thank you.
