When using Internet Explorer 7 with any of our secure websites (like WebMail and RosterOn) you are likely to get an error message like:
Please just choose "Continue with this website (not recommended).", even though it says it is not recommended. Note that this is not something we would normally encourage and we are working on the problem so that our secure websites comply with the improved security features of IE7.
Also, while you are using the website, your address bar will be coloured red. Again this is something we are working on.
