According to this article https://community.dynamics.com/crm/b/dynamicscrmsupportblog/archive/2015/07/10/dynamics-crm-support-with-windows-10-edge-browser-and-office-2016 CRM versions 2013 and 2015 will be supported when accessed from the Edge browser in Windows 10.
| Version | Update in which support is added for Windows 10 |
|---|---|
| 2013 | Update Rollup 4 for SP1 |
| 2015 | Update 0.2 |
| On-line | Update 1.1 |
Therefore, it seems that versions 2013 without SP1 and 2011 and earlier will not be supported.
