I thought I’d give it a go and see how far this would take me. (One of the Win8 x64 beta installs caused alot of grief)
So my environment:
- Recent Win8 RC x64
- Office 2010 x64
- Outlook 2010 x64
Installed the CRM 2011 Client by going to the web address of our crm site e.g. https://crm.acme.com
There’s a button on page that says ‘download Dynamics CRM for Outlook’ – after a short download and install all went well
I grabbed CRM2011 CU8 - http://www.microsoft.com/en-us/download/details.aspx?id=29692 and updated accordingly.
Note at this point CRM plugin had not been configured.
CRM Client Log files prove very helpful here:
When I fired up Outlook and went to configure the CRM Plugin, Testing connection I would get back
“…we can’t authenticate your credentials…”
Digging into the log files…..

Solution: Install the Windows Identity Framework 3.5 that comes with Win8 RC.

And in my case, you’re done.
Happy CRM-ing.
Now to fill in my timesheets
