Ik heb een tijdje me OWA niet gebruikt dus weet niet precies sinds wanneer dit is. Enigste wat tussentijds is gebeurd is dat ik PHP heb proberen te instaleren en dat niet gelukt was en daarom weer geüninstalled heb.

Wat zou dit kunnen zijn?

Oja ik draai Windows Server 2003 Enterprise met Exchange 2007 SP1.

Mag dicht, EXCH2k7bleek makkelijk de CAS geherinstaleerd te kunnen worden en is zo gelukt.
