When using the Exchange Remote Connectivity Analyzer (ExRCA) using the Office 365 Microsoft Single Sign-on (BETA) tool you may experience the following error message.
ExRCA is attempting to retrieve and analyze a security token for user firstname.lastname@example.org.
An error occurred while attempting to retrieve and analyze the security token.
ExRCA is attempting to authenticate to the security token service at https://fs.4logic.com.au/adfs/services/trust/2005/usernamemixed.
An error occurred while attempting to retrieve the security token.
Tell me more about this issue and how to resolve it
The Security Token service indicated that the authentication failed. Check the user name and password and try again.
I have seen this problem occur in two circumstances:
a.) the username and password you have entered is incorrect.
b.) the UPN suffix for the user account has not been updated yet to a public UPN suffix. Do this in AD Users and Computers. I set it to @4logic.com.au.
You may have to create a public UPN suffix under Active Directory Domains and Trusts first.
