After a long run, Microsoft has confirmed that they will officially stop supporting IE 11 on August 17th, 2021 across it's entire product line and even security patches. ZenQMS releases starting this year with 2021.1 will stop supporting IE other than major security considerations on a risk-based approach. This also means there is a limit to what the helpdesk can do to cure IE related issues.
For all those who haven't moved to the new Edge, Chrome, Firefox or Safari-- please do and keep up to date. The new browsers are much faster and more secure.
