Like many companies, the company I work for is mainly IE6. The older machines are running Windows 2000 and some of our clients applications (applications we have no control over) don't work with IE7.
We recently tested Gmail Apps to use for the majority of our agents and one of the biggest problems with the web interface was the lack of features that are available in other browsers. With the newest version of Gmail, this is a problem of the past.
Gmail has been working with IE engineers at Microsoft to fix some of the problems they found with their code and how it works with IE6. In order to see these changes you will need to install the latest updates from Microsoft (or specifically the update described in MS08-022).
New confirmed features for IE6 users include colored labels, invisible mode and Gmail Labs. With Google trying to compete in the enterprise email sector I believe this is a step in the right direction. What do you think about this change?
