We’ve had a few issues recent in regards to the CRM 2011 Outlook add-in on Windows 8.

The issues manifested there selves in a two different ways.

  1. First being that we couldn’t install the CRM client due to the Installation of Windows Identity Foundation failing
  2. CRM Client installed but we were getting connection errors even after typing the correct CRM URL.

We resolved this by adding the “Windows Identity Foundation 3.5”  and all started working.
