The documentation System Requirements only refers to Internet Explorer 7, 8, 9 and 10:
Internet Explorer requirement:
- ArcGIS for Desktop requires a minimum installation of Microsoft Internet Explorer Version 7.0 or 8.0. If you do not have an installation of Microsoft Internet Explorer Version 7.0/8.0, you must obtain and install it prior to installing ArcGIS for Desktop. Internet Explorer Versions 9 and 10 are also supported.
Is ArcGIS for Desktop 10.1 fully compatible with Internet Explorer 11?
Thanks.
don't know if it has been approved but no issues other than copying code blocks from the GeoNet site...ArcMap has no issues that I have detected...besides IE 8 and 9 were quite some time ago
