Bei den Preview-Handlern ist eine CLSID registriert.
Diese CLSID muss du unter HKCR suchen.
Unterhalb des CLSID-Wertes steht dann die ausführbare DLL mit z.B. InprocServer32.
Die 32 hat hier nichts mehr mit der Bitness zu tun.
Ich habe bei mir noch mal geschaut, der Explorer läuft uinter 64-Bit!
Somit benötigt der Explorer eben auch 64-Bit-Handler.
Für normale msg's ist bei mir die inetres.dll unter 32-Bit (WOW6432Node) und 64-Bit registriert.
Für HTML-Handler ist bei mir inetcomm.dll jeweil unter 32/64-Bit registriert.
Die DLL's müssemn natürlich in den jeweiligen Verzichnissin (System32/Syswow64) vorhanden sein.
Dies sind nur die jeweiligen Handler. In wie weit diese nun wieder auf Outlook zugreifen kann ich nicht sagen.
Allerdings ist der Explorer nun 64 Bit und Outlook nur 32-Bit.
Nachtrag:
Nachrichten werden im 32-Bit-Prozess "Prevhost" angezeigt.
Über den Sysinternals Prozess-Explorer kann man sich die geladenen DLL's anzeigen.
Hier gehören einge MSOxxx.dll's.
Hier eine aktuelle Auflistung der DLL's. Ggf. fehlen da ja ein paar bei dir.
