A New Bug in SP4 for Exchange 5.5 ?

Hi,

since i have installed SP4(German) for Exchange Server 5.5 (German), i couldn?t create Custom Adressbook views. I get the Error “DS_E_INSUFFICIENT ACCESS_RIGHTS”. This wasn?t a problem befor SP4 for NT.
A Workaround is to Logon as the Service Account for Exchange, then it is possible to create these adressbook views. It is not an NT-account problem, i had tried everything to check that.

Any one an Idea ?
