Hi Prasanth,
It might help to explain what problems you are having and the specific version of Internet Explorer. Is it only Internet Explorer 11?
Check the patterns page (and for OSUI) to see if the issues you are experiencing also occur there. If the issue does not appear there, there could be something in your application causing a problem, possibly JS or CSS related. It might also be worth creating a sample application to replicate the problem, which would help rule out any issues being caused by your application.
I am in the process of building a large enterprise application using Silk UI which must support Internet Explorer 11. While we have found one or two small issues, for the most part Silk UI is performing well on IE 11.
This page explains that SilkUI supports Internet Explorer 8 and up, but with some limitations, though it does not say what the limitations are

Silk UI Web is built to support all modern browsers such as Chrome, Firefox, Edge, Safari, Opera and all modern devices such as IOS 7+, Android 4.0+ and Windows Mobile 8.1+. Internet Explorer, starting with version 8, is also supported, but with some limitations (check patterns documentation for IE8 compatibility).
Silk UI Mobile follows the same requirements as OutSystems Now, Android 4.4.2+ and IOS 8+.
For OutSystems UI, it is meant to support Internet Explorer 11, although I notice there have been some reports of compatibility issues
