SSO stands for Single Sign On, sometimes is also used for "seamless" Single Sign on, meaning you can authenticate to O365 services without ever seeing a password prompt. To get this experience, you need to either have AD FS configured with O365 or use the new AAD Connect SSO: https://docs.microsoft.com/en-us/azure/active-directory/connect/active-directory-aadconnect-sso

Well, since the older password is no longer valid, that's the expected behavior. Otherwise users will just get disconnected and wont understand what's happening.

In general, the password is stored in the Credentials manager, so you can remove/update it from there. If you want to avoid users getting prompted for passwords, you will need to use a modern Outlook client and deploy some form of SSO.
