[Gelöst] Serverfehler in der Anwendung /ecp

Hallo,

Exchange 2019 cu13 Juli sv2. Alles läuft problemlos, auch /ecp scheinbar.

Wenn ich einen neuen Benutzer per ECP hinzufügen möchte und z.B. auf "vorhanden" klicke oder Benutzer einer Gruppe hinzufügen möchte erhalte ich neuerdings einen "Serverfehler in der Anwendung /ecp" Kompilierungsfehler. (Versionsinformationen: Microsoft .NET Framework-Version:4.0.30319; ASP.NET-Version:4.8.4654.0)

Mal abgesehen davon, dass es ja bereits ein Oktober SU gibt, das noch nicht installiert ist.

Hat soetwas schon jemand beobachtet?

Danke und Gruß
