The 5th and only the 5th personal folder on my email account will not open any email filed there and freezes my account every time I open this folder. Again, this ONLY occurs in the 5th (alphabetical order) Personal Folder.
Try clearing out your browser's cache/browsing history. When you have done that, close out the browser and re-start it in a fresh session. If that doesn't do it, then try using a different browser.
I will try those suggestions, but what is perplexing is that this only happens in the 5th folder in alphabetic order. All other folders prior to or after this one works just fine!
