General issues that may occur for one or all users
Topic Last Modified: 2012-02-24
The Microsoft Exchange Remote Connectivity Analyzer tool queries the Authentication Platform in the cloud to perform a realm discovery. When that process is finished, the Authentication Platform passes to the requesting client the ADFS endpoint URL that the client requires for authentication. The tool performs the authentication on behalf of the user to simulate authentication to the Office 365 environment.
If the Remote Connectivity Analyzer tool displays a warning at this stage, the message can indicate any of several different issues. Because the authentication process involves many steps, the solution that is required for a returned error or warning is not always obvious. For example, you might receive one of the following messages:
There was a problem accessing the site. Try to browse to the site again.
Your organization could not sign you in to this service
The following are some of the issues that can cause such generic errors:
Stale Identity Federation information in the Office 365 environment
Incorrect Identity Federation information in the Office 365 environment
Recent UPN change issues
Various Firewall settings at the ADFS endpoint
Because errors such as these are fairly generic, the solutions will vary widely. The “More information” section includes several different methods for resolving these issues.
