cant send email

[Paulammo]

I can receive emails from my blueyonder account but I can't send this has been happening since around the time virgin were messing around with o2 .

I get this,  The entered credential or authentication information does not work or are no longer accepted by provider. Please change them.

I wouldn't have a clue and I don't want to lose my emails

The above highlighted error message can usual be resolved by:

1. opening an Incognito / Private browser window
   
   
2. sign in here https://mail2.virginmedia.com with the authentication credentials of the problem account; in the above example it would be richard.branson@blueyonder.co.uk.
   
   If sign in is unsuccessful try the forgotten password link Forgotten your Password? | Reset Here | Virgin Media
    
3. once successfully signed into webmail go to Login to My Virgin Media | Virgin Media and select Sign in
   
   
4. select Account settings > Virgin Media Mail settings > Generate new App password
   
   NB if prompted to “Verify it is you” then follow the instruction to change your Sign in Email Address to a non-Virgin Media one. Once the verification process is complete repeat step 4
   
   
5. make a note of new App Password
   
   
6. sign out or close window
   
   
7. now back in webmail, select Edit located adjacent to problem account; in above example that would be richard.branson@ blueyonder.co.uk
   
   
8. scroll down to Incoming server section and enter App password, noted in step 5, in Password field
   
   
9. scroll down further to Outgoing server (SMTP) and set Authentication to As incoming e-mail server
   
   
10. select Save
