I am unable to search for e-mails that are more than a few days old in my Outlook.com.  This is on a PC NOT a mobile device where there are settings that allow you to store only x number of messages in your inbox.  In fact, when I try to search messages that are a few weeks old, I cannot find them.  Yet, I have messages dating back to 2000, so they are there, but I cannot use the search function. Please advise how to restore default search functions to find e-mails by a name - not just from and by as keywords.  Outlook.com is really not easy to navigate.
