Hello Kerry -
Unfortunately, rework to the Manager to support the IE8 browser could not be completed for the 10.2.2 stability release. The development team has incorporated changes supporting the older browser into our daily builds of the 10.3 product, but please be aware that while all of the Manger's pages are rendering for us with these changes, the controls and page layout is not optimal. The results so far are impacting the Manager's functionality.
Do your users have an option to use Chrome or Firefox on their systems? Keep in mind that if the Server itself has restrictions on what can be installed, it might be possible to manage the Server from a client machine onto which a later browser release can be installed.
Hope this information helps -
RJ
