just check if your thunderbird is not offline check too if u have enough free space on ya drive too

Go to the Hotmail site and turn pop back on. Microsoft probably turned it off .

Shey Louis Chia:

Thank you, but I've got 240GB spare empty space on that drive, and Thunderbird is not offline (I didn't know it could go offline!)!

Airmail:

Thank you, pardon my slowness, but how to turn pop back on, please, I've never changed it from how I set it years ago when I first set up Thunderbird

This is a Microsoft problem. They are converting all their free email accounts and every Hotmail user with this error has discovered that POP has been turned off in their account. This is something that you fix by logging into your account with a Web browser at the Hotmail page. You need to ask Hotmail for help if you cannot find it yourself.

Aiemail:

Thanks for second reply. I will give Hotmail a go - but first to the gym to clear the cobwebs out of my head before i try anything else. Thanks for your help.

Airmail: thank you again - I figured it out ands now all is well again! Thank you again
