WLM garbage software? I used Windows Live Mail for many years and really liked it until about a year ago when MS changed the protocol that it used for Hotmail/Outlook and refused to update WLM to support it. I switched to Thunderbird at that point. IMO, Thunderbird isn't as good as WLM but it works sufficiently well and I haven't found a better alternative. I tried EM Client and didn't like it at all. I can't stand the mail app that comes with Windows 10.
If MS announced an update to WLM in order to support Hotmail again, I would switch back to WLM in a heartbeat. Never had any problems with WLM and Hotmail. I've been using Hotmail as my main personal email for around 20 years and it has never failed me. I have a gmail account but can't stand gmail and don't understand why it's so popular. My ISP provides me with an email account also but I never use it except to communicate with my ISP.
Don't have any advice for the OP regarding the issue being encountered other than to try an uninstall/re-install.
