I still can’s see the arrow to get a drop-down menu in Outlook.com. I tried clearing the cache as some articles have suggested. I’m using Internet Explorer 8. It’s been suggested that I need to upgrade Internet Explorer, but you can’t go beyond 8 in XP. Any suggestions?
Jay, I would suggest using either Google Chrome or Firefox to access Outlook.com That should take care of the display issue. You can download either browser for free if you do not already have them installed on your computer.
Get Chrome by clicking here. 
Get Firefox by clicking here.
