Cita:Hotmail inaccessible The issue with Safari 4 and Hotmail is universal. Sure you can look at emails by changing your user agent but try replying to one. I have had any problems with anything else (including Gmail) and I have no addons.

You can resolve some issues with Hotmail by changing the Safari user agent. First enable the Develop menu (if you haven't already) via this process: Launch Safari, then navigate to Preferences>Advanced and choose to show Develop in the menu bar.

Next, login to Hotmail, then go to the Develop menu and choose User Agent>Firefox.

Unforunately, a number of users are still experiencing issues sending mails after switching the user agent.

Text entry problems Some users have reported problems entering text in specific forms or javascript-powered Web apps after the update.
