yes that was the complete output. Every sync, same output.
I can't answer the question why it removes the account state.
For my tests i sync manually on my Mobile under "Einstellungen, Konten, Exchange, Jetzt synchronisieren" (could be in English "Settings, Accounts, Exchange, sync now" or similar)
The Settings for the Exchange Account on my mobile are default. Except no ssl (for the time of testing) and deactivated sync for E-Mail and calender but activated for the contacts.
