Participating Lync could not connect. Please check your login credentials and try again

With the help of OC 2007 R2 Version 3.5.6907.225, but I invited Lync users meeting. So I downloaded Lync 2010 Attendee on a per user level.

But is a mistake when joining by using the credentials of company, here is the error message:

Participating Lync could not connect. Please check your login credentials and try again.

Can I join as a guest, however.

Thank you.
