The only answer I can offer at the moment is to return to the "old" Outlook until the "New" Outlook is up to speed.
I'm disappointed that the "Run all Rules" option is not available. I have over 100 rules that I use to organize my inbox and subfolders. To have to select each rule to run that rule now is a task I will leave to someone who has the time. I'm still looking for a way to run the rules automatically when Outlook first opens up. I can appreciate improvements and a polished product. This is not a finished product.
