Outlook 2013 – has a new default search when searching for email within your Inbox. The new default is to search the entire mailbox – not just the current folder; whilst this is a welcome improvement that I would love to have seen implemented in earlier versions of Outlook – as a default it’s normally overkill and returns more results than I actually want (usually because my mailbox subfolders are where stuff gets stored after I have dealt with it). So, how do we change that default?
A quick google web search turns up the following article, which quickly and easily shows you how to return it to its original behaviour, and fix this niggle, without losing the ability to perform ad-hoc searching on the whole mailbox when needed.
