Although this case was reported a year ago, I started having the same problem with my account this morning.

As a family of 4, we share computers. In the windows live mail, we have account set up for each of us. But this morning, I found out that while my daughter and my husband's email worked as normal, my son's and mine stopped working with the exact errors displayed.

I would say it actually already stopped working last night since an outgoing email I tried to send before midnight never went out.

I decided to remove and re-add my own account. Well, a bad move I regretted. Now my account is dead, no syncing, not active at all. If I try to re-send the message, it would complain the sender email is invalid.

I have been with hotmail for so many years, and I have already encouraged my kids to stick to Microsoft simply because I personally liked it even though I've seen enough bad things. Now with this happening, I am really getting sick of it.

I don't like the new Mail with Windows 10. Looks fancy, but I hate it. I want something simple and straightforward, I don't need any fancy background, it doesn't add any value and is no fun. That is why I chose to stick to Windows live mail. Now I don't know what to do.
