You guess it, they are not compatible. When I try to load our CRM 2011 application in my IE 11 browser, it attempts to load the mobile web page.

That’s because the Microsoft team decided that it might be a good idea to change the User Agent string in IE 11. I disagree.

There are two workarounds for this issue, other than using Chrome or upgrading to CRM 2013 (yes, it is fixeddoes not appear to be an issue in this version).

  1. Use the full CRM URL, including the main.aspx page, i.e.
  2. Run your CRM web site in compatibility mode. (This is a good idea if you’re also running SharePoint 2013 sites. Yes, there are issues.)

To run IE 11 in compatibility mode, follow these steps:

  1. Choose ALT-T
  2. Click Compatibility View Settings
  3. Add the current site to your compatibility view
  4. Choose OK
