On 'check mail', kmail asks for password and username, when entered doesn't work

[Shabakthanai]

This has happened before, but I cannot remember the fix, and google search is too confusing about the issue.

Recap: When I select 'check mail' in kMail, it asks for username and password. Username and password are pre-entered, when I click on the option, it does not open the mail. Kubuntu 17.04.

Is KWalletManager running (Open) and showing Kmail2 's various details saved while Kmail is up?

I can't remember how to find what you are describing. Searching confuses me too. Shab
