Ok so the Mail app on my 2011 MacBook Pro has been faultless since I got this machine almost a full 5 years ago, that is until last week when every time I opened the app it wouldn't load my emails and gave me the message 'could not login' or similar and asked me to re-enter my password, which I tried several times and every time it said it was not able to verify the account. So today it still wasn't working and I decided to just delete the account and then re-add it to see if that worked, so I deleted my hotmail account. I then tried to re-add the account and it says "the account already exists" and wont let me re-add my hotmail account to the Mail app. However the only other account listed is my iCloud account that uses the same hotmail address apparently when I view its details. No idea what purpose the iCloud account actually serves apart from doing backups of my iPhone. So now Im wondering how I can re-add my hotmail account and start receiving my emails again? I'm lost. Many thanks!
