Issues with SharePoint 2013 with Internet Explorer 11
So if you are one of the few that are using IE11 and SharePoint 2013, you have probably noticed many corruptions and misbehaviors in the UI. The following problems have been discovered:
- Calendar web part is extremely corrupted.
- You click Settings > Edit Page, pages will not enter edit mode.
- Web Part Properties cannot be modified.
So until we get an official CU or SP from the SharePoint team, run your sites in Compatibility Mode.
How to run Compatibility Mode:
- Press ALT + T when viewing your SharePoint page
- Click Compatibility View Settings in the menu that appears
- Click Add to add the current SharePoint site to your list of compatibility view pages
- Click Close
