Designed to be fast - The Outlook on the web user experience gets simpler and more powerful

Web Outlook email processing rules have gotten more powerful, but the functions to manage them are still extremely slow and far too primitive. An automated function to CONSOLIDATE multiple rules to move messages into the same folder could dramatically streamline rules admin and fault diagnosis. The automatic function to create sorting rules wrongly defaults to very specific email identities when instead it should default to selecting emails based on the source domain. 

Finally, adding emails to folders should not immediately remove them from the inbox before users have a chance to see them. Microsoft and other email platforms should have learned from the Google Gmail approach to folders, deriving their contents from the TAGS which are applied to messages. In that way, messages can be in one folder, multiple folders, or none (all mail). It will be difficult to ever user Office 365 as a primary email platform until it's old primitive way of placing messages in one folder in a rigid hierarchy has been retired.
