Internet Explorer 8 lets you to access multiple Gmail accounts. It provide users to access multiple Gmail accounts simultaneously and independently.
This is accomplished via the New Session option, which makes it possible to log onto Web sites that track your identity across different tabs--like Gmail.
Here's how to utilize this IE8 feature:
1. Open Internet Explorer 8 and login to your Gmail account. Make sure the Remember Me option is unchecked when you sign in.
2. Press Alt-F, I, and then hit Enter. This will open a new Internet Explorer session (which for all intents and purposes is the same as a new IE window).
3. Open Gmail and sign in with different account, again making sure to uncheck Remember Me.
