Question about Outlook Express

I am using Windows Live Mail on Windows 10. Like others, I have found that copies of emails are not appearing in the Sent folder. Checking the mail account on another device or by (Outlook) webmail reveals but does not fully recover to WLM the sent emails.

More critical is the complete loss of received emails. A recently created folder had four or five important emails copied into it from a different email account. They were available in it but now Send/Receive shows only the folder with an 'Empty' message. Also:

Unable to send or receive messages for the Hotmail (name) account.

Server Error: 0x80070057
Server: 'https://m.hotmail.com/Microsoft-Server-ActiveSync'
Windows Live Mail Error ID: 0x80070057

Deleting the Hotmail account and reinstating it has failed to achieve the required result, and failures to sync as reported above are routine.

The first error code above reports something on the server. Thinking to address the second I downloaded TechUtilities which found 2,880 'issues', all of them referencing non-existent files. To fix them I was invited to register, but this was only a cover for buying something that I judge not to be needed.

How long should we wait for Microsoft to patch this up? Or just switch to Gmail?

I clicked something that caused me to lose my folders and the emails stored in them. I can find the archive that has the folders and the emails. Any suggestions?

[Original subject: Something happened in Windows Live Mail]

I tried to send these two email and received the following error message.

 I no longer want to send these messages.  How do I stop getting the error message?  Every time I send a new email it will go through but these two keep showing up as errors.  I see what I did wrong in my attempt to send the emails but now I just want to stop attempting to send them.

Thanks,

John

The message could not be sent. The setting for your outgoing email [SMTP] server might need to be configured. To find the server settings for *** Email address is removed for privacy ***', please contact your email service provider.
