    I have a continous error in my OCS2007 "Cannot Synchronize address book information" since I installed OCS 2007.

    Server configuration:-
    Windows 2003 Std. - Domain Member
    IIS 6.0
    CA

    This is purely for internal IM communication. IIS on this server is also hosting thrid pary SSL on default website (no SAN  support ssl).

    Exchange 2007 sp1 is installed on seperate server.


    There is no proxy settings in the IE.

    I also tried following website with no luck.
    https://servername.domain.com/abs/int/files/Sample_Company_Phone_Number_Normalization_Rules.txt

    Please suggest. Thanks.

    Check your spn i.e. service principal name and make sure it is there for your pool.  Also check the following caching settings on your server.  I have a similar deployment and I had the same issues:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings 
     On the Edit menu, click Add Value, and then add the following registry values:
    "BypassSSLNoCacheCheck"=Dword:00000001

    Many thanks for responding.

    I have checked that SPN is registered for the pool. But I am little hesitant to modify the registry.

    With this https://servername.domain.com/abs/int/files/Sample_Company_Phone_Number_Normalization_Rules.txt I got the default txt file in IE.


    Let me be more specific about the scenario.

    On my default website the SSL we have is for owa say "login.domain.com".

    If I see Front End server properties-> under connections. I have Address "All" Port "5060" and Transport "TCP"

    And Certificate for this is locally generated through CA say "OCS.domain.com"

    Does this configuration sounds ok?


    Thanks for your time.
