I can’t open my emails and I can’t switch folders.

If I exit outlook hotmail and re-enter I can switch folders once, but cannot open the emails in the folder. Sometimes if I am able to open my inbox I can read the emails but it doesn't work consistantly. If I exit outlook hotmail and re-enter I can switch to a diffeent folder, but cannot open any of the emails in the folder. I cannot switch folders unless I exit and re-enter outlook hotmail. The only folder that sometimes permits me to read the emails is the inbox. None of the other folders permit me to open archived emails.
