When I attempted to configure one of our user’s Meeting settings using the Microsoft Office Communications Server 2007 R2 Administration Tool


I received an Validation failed – Validation failed with HRESULT = 0XC3EC7E02 dialog box error message.


I received the same error message when I tried to configure the user’s Telephony and Other settings.

Using ADSI Edit, I compared the settings of an user that I had no problems configuring and the user that I had problems configuring.  For the user I had problems configuring, I noticed a trailing space after the last phone number digit for the user’s msRTCSIP-Line attribute.


After I removed the trailing space for the attribute and waited for Active Directory replication to complete, I was able to configure the user’s Meeting settings (and Telephony/Other settings) without any problems.

If you get the error message, check your user’s msRTCSIP-xxxxx attributes in Active Directory using ADSI Edit for any trailing spaces, typos, or any other mistakes.

Great info. We are in the process of migrating to 2010 and running into the same issues. Thanks for taking your time to do this.
