Hello Marc,
Unfortunately this error message can mean many different things depending on where and what you are doing in the CRM 2011 Outlook Client.
If you are receiving this error message when trying to Configure the CRM Outlook Client for the first time. I would verify the following information:
1. Ensure there is no firewall blocking access on the CRM server and the Workstation
2. Ensure that the CRM Server url is listed in the Local Trusted Sites List, in I.E. Settings for the workstation.
3. Verify in the I.E. Internet Options Connections Tab, Lan Settings Button, that Automatically detect network settings is checked. Or you have manually entered a proxy server if your organization is using one.
4. The Configuration Log may provide you with more details as to why it won't configure. in a Windows 7 environement this file can be found at c:\users\<user account logged in as>\appdata\local\microsoft\ mscrm\Crm50ClientConfig.log
If you receive this error message when using CRM, such as trackign an email, contact, appointment, synchronizing with the CRM Server. It would start by checking the following items:
1. There is no Firewall or Proxy Server blocking/interfereing with communicate to the CRM Server
2. The CRM Server URL is listed in the Local Trusted Sites, in I.E. for local networks.
3. The CRM Server URL is listed in Trusted Sites for IFD URLS.
4. Automatically detect Network settings is enabled in I.E.
5. Users security role has proper permissions to perform the action.
