Exchange 2019 Datenbank kann nicht eingebunden werden

Hallo,

ich habe ein Problem mit meiner Exchange DB.

Die Datenbank befand sich im "dirty shutdown". Ich habe sie mit dem Soft Repair (eseutil /r) wieder auf Clean Shutdown bekommen:

Jedoch erhalte ich beim mounten folgenden Fehler:

Gibt es noch Lösungsvorschläge?
