Question about Outlook Express

I recently experienced a crash which required uninstalling and reinstalling Windows 7 via the recovery files that came stored on the computer. I downloaded and installed Windows Live Mail 2012 and loaded backed up emails, contacts, etc. into it. Everything appeared to be working fine for a few day. Now, all of a sudden, emails that I delete come right back and appear in the Inbox and All Mail folders. 

I want to replace Live Mail with Outlook 2003, but I want to first delete several messages that I don't want to import. Please help.

I have just installed the windows 10 upgrade to windows 7, and then also installed windows essentials.

I have imported my contacts from my windows xp computer via the wab file.

There are a lot of duplicates so I have clicked "clean up contacts".

Sadly, every time I try this, a window pops up saying my username or password for my Microsoft account is wrong, and the "clean up contacts" process never begins. I can assure you, neither my username or password is incorrect. Indeed if I hover over the account button, it states quite clearly that I am signed in.

How do I fix this please?
