Why am I unable to open email or a calendar?

If you are experiencing a problem opening email or a calendar, check to see if you have a pop-up blocker or a Google or Yahoo Toolbar (Companion). Yahoo Instant Messenger is an indicator that you have the Yahoo Toolbar installed. Common locations for a pop-up blocker include: Windows with SP2, ISPs such as AOL, MSN and Earthlink, search toolbars such as Yahoo, WebSearch and Google, and certain browsers such as Netscape as well as Norton Internet Security and McAfee Security Suite software which you will need to turn off. To review pop up blocker information, visit our pop-up blocker FAQ page.
