Any time I try to take any action such as open or delete, the Outlook application freezes.   To try to resolve this, I have deleted my history, temporary internet files and website files, and cookies and website data.  I have restarted my computer.  This problem started about October 17, 2013, and has been continuous these past 5 days.   I have two other Hotmail accounts, and they are working without problem. 

After doing all that Denise T. recommended (optimizing browser, clearing browser's cache and temporary internet files), still not able to view email photos in slideshow - must download them all.  Why?  Never had a problem with this before Outlook "upgrade" of hotmail.
Cannot access or empty Junk Mail folder or Draft. This sucks. What is going on? Yes, I've cleared my browser's cookies and temporary internet files. They are not causing this issue. I've NEVER had this problem until I was converted to Outlook.com, without my permission or knowledge. Total ****. I need to be able to access my Junk and Draft folders. What is the solution? And, don't blame it on anything other than Microsoft's problem/error.  I cannot logout because everything freezes as soon as I login. This has never happened with Hotmail. This has only happened when I was converted to Outlook. Horrible customer service. Ugh.
Operating from a Mac using Firefox, Email frequently wont load, I receive the message above. Have deleted temporary internet files and cache, and tried using Safari instead of Firefox, but still no improvement. Any ideas....
