Groupwise Webmail on Vista?

I can't access Groupwise from my home Windows Vista computers.   Do you have any ideas how I can remedy this? 
There are a few possible solutions to this issue.
First, let’s make sure you are going to the right place for Groupwise webmail.
Next, there is a setting that needs to be changed within Internet Explorer when using Windows Vista.
Open "Internet Explorer"
Click  "Tools"
Click "Internet Options"
Click "Advanced Tab"
Scroll to "Security Settings"
Uncheck "TLS 1.0"
Click "OK"
Close and reopen Internet Explorer.
 
This should allow you to log into Groupwise webmail.
 
Another alternative is to use the Mozilla Firefox browser. Firefox is easily customizable, and inherently more secure than Internet Explorer. (less bad stuff will get on your machine.)
