It seems that every time we add an AJAX feature to Web Mail to improve the usability for the vast majority of users, a few users report strange problems with those features being blocked or not working right. These problems almost always turn out to be that some security software running on the user's computer is blocking the use of those features, but doesn't give them any warning or information about what is wrong. Keep reading for instructions on how to fix this problem.
- The folder tree in the left panel - you can expand and collapse the folder tree and any nested branches you create, and these update immediately when clicked without having to refresh the page.
- The Write Message view - when you click this to compose a new message, the view updates immediately without having to refresh the page.
These features make Web Mail faster and more interactive for the user. But sometimes users report them not working. On Write Message, the problem usually shows up when replying to a rich text (HTML) message and usually doesn't interfere with plain text messages. See this post for more information. On the folder tree, sometimes folders don't show up at all, or don't respond when clicked.
