Outlook for Android search issue

Raizel 

I was looking for a solution to the search functionality not working on my Outlook for Android app, which led me to this discussion.  I have just found the solution by chance..   Every time I used the search function it always showed 'no results'.   If I click on the down arrow next to the search function, the search default was to my hotmail email (microsoft email), which I rarely use, but it wouldn't let me change to one of my other email accounts.  A get around it to click on the house icon for 'all accounts', and the search function worked!  I hope this works for everyone else.
