Hi, I have installed tan exchange 2007 server in coexistence witha 2003 exchange. After installation the Exchange2007 readiness shows an error " permissions inheritance block on exchange object....CN="First Administrative Group". I have enabled the security page on the exchange 2003 server manager and the allow inheritance on First Administrative Group properties\security tab are ticked and enabled. Any ideas how to resolve this? Theos

Hello, I hope you restarted the Exchange server after doing this change, if not then restart it and check. Permissions Inheritance Block on Configuration Object http://technet.microsoft.com/en-us/library/aa998240(EXCHG.80).aspx
