Galaxy Reverb reset password in phone

I cannot reset my password on my phone, it only shows email from before I reset my password on pc.  I have a Samsung Galaxy Reverb digital phone.  I have outlook email on it.  Someone tried to hack my "Hotmail" my Galaxy email used to work but as of Oct 23rd 2013, it stopped updating and only has emails prior to my changing the password via my pc.  I can access my email.  But VirginMobileUSA my carrier says to ask Microsoft if I need to replace my phone.  I deleted the Hotmail from the phone, restored it and no luck still only old emails no new ones.

Then with Carrier's assistant tried to reset IMAP settings still no updates.  The phone appears to retain the old password and is not resetting, nor going to a screen to change password and verify password.  So I need to know how to correct update the digital Galaxy phone with the new current password.

Or must I replace the phone which my carrier will do?
