Question about Outlook Express

Unable to send or receive messages for the TWC Mail account. An incorrect password was entered. The next time you send or receive messages, you'll be asked to enter your user name and password for this account.

Server Error: 0x800CCC90
Server Response: -ERR [IN-USE] account is locked by another session or for maintenance, try again.
Server: 'mail.twc.com'
Windows Live Mail Error ID: 0x800CCC92
Protocol: POP3
Port: 110
Secure(SSL): No

I have read several forums and applied all the troubleshooting solutions: Correct passwords with the username by making sure I enter the full username email address. Nothing has worked. What I am uncertain about is the server response: account is locked by another session or for maintenance. try again. ????? What does that mean?  I need help here and cannot find any way to send/receive emails using WLM after trying everything I could find online about this problem. Any suggestions?   

Anyone have a solution to WMM 6.0  working properly on Windows 10.     Once you have about 15 minutes or so on the timeline the process slows and continually says "not Responding".       Takes so much time and patience to produce a family movie!

Tried using Windows Live but that has many issues including problems of adding music and transitions.

I am trying to add my outlook.com account to Windows Live Mail, and keep getting this error once I added my account:

*** Email address is removed for privacy ***

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

Server Error: 3219
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x8DE00005

My outlook.com account has been switched to Outlook Mail (Preview) when I log into it through a web browser.

Any advice???

Thanks in advance

i have just reinstalled this program and it still shows all different logos among  my pictures .How can i make this program load

  Just the pictures i take.I am using a laptop with windows 10.

About 3 weeks ago, my MS Live Mail stopped sending out my emails.  I still receive email just fine.  Other computers in the office using the same ISP are working fine.  I have double checked the SMTP protocol settings: nothing has been changed.  I have not had any new updates or installs.  

An unknown error has occurred.

Server: 'smtp.qwestoffice.net'
Windows Live Mail Error ID: 0x8007007A
Protocol: SMTP
Port: 465
Secure(SSL): Yes

I tried the alternative port 587 without success.

I'm not sure what else to try.

Split from this thread.

I am using Windows Live Mail. Yes I am able to sign into Hotmail.com/Outlook.com. I never thought of trying it on web mail. Yes I received an error message and error code, the code was 3219. No there were no changes on the settings prior to this issue
