You are welcome.
I still don't understand how opening webmail in a browser, which is supposed to do every thing outside your own computer, empties your local Thunderbird.
To get that done the server used by Thunderbird must have been emptied. That can be done by another email client connected...
If I read and understand this, your disapeared mail showed up in your live mail, with other words live mail synchronizes with your local email client.
How did you open live mail?
- Go with your webbroser to Outlook – free personal email and calendar from Microsoft, then login into live mail?
I read that you did a reinstall of W10 with the medium of your previous PC.
Just a question. Have you ever tried just leave the new PC as it is, and only entering your account and coping your files over? That should be the way without any problem.
Yes, what on earth can possibly cause that webmail,
- using Edge open https://oulook.com
> login using your livemail accountname
> open webmail
which is supposed to do every thing on-line and nothing on your local computer, empties a local Thunderbird folder???
I have to think this over....
