Message at login to users with unsupported Internet Explorer versions
Many websites, such as Facebook, Youtube and Gmail are no longer supporting old versions of Internet Explorer. Older versions of Internet Explorer(IE) have security problems which will never be fixed and using it will leave you vulnerable to all sorts of problems on the internet.
Suggestion: Users receive a message saying that their browser does not meet the minimum requirements for accessing Leganto upon trying to log in with an unsupported browser. They may still be able to log in, but will not be able to view/use Leganto effectively. This has been done for other systems, see for example the attached picture for the message IE-users of Canvas LMS receive.
As of now, Microsoft only supports the following desktop operating systems with Internet Explorer browsers:
Windows 10 -> Internet Explorer 11
Windows 8.1 Update -> Internet Explorer 11
Windows 7 SP1 -> Internet Explorer 11
(see full list of operating systems that support IE11: https://support.microsoft.com/en-au/help/17454/lifecycle-faq-internet-explorer)
So this could be used as criteria for which users receive the message. And to avoid making reading lists inaccessible for non-logged in users I suggest that Ex Libris only shows the message for users attempting to log in.
Once Ex Libris finally deprecates support for Internet Explorer completely, all users trying to log in to Leganto with Internet Explorer should receive this message.
