Hello. Exchange 2019 on-premise. I have a task to configure ThunderBird via IMAP.
This mail client automatically finds the settings and connects:
Translate:
Обычный пароль - Basic password
Метод аутентификации - Authentication method
Basic and NTLM are used by default. I know this is not secure. + Microsoft Recommendation advises to disable NTLM and Basic.
- Is IMAP able to work via Kerberos ?
- Is SMTP authentication via kerberos supported in IMAP?
What are the recommended settings ?
The notification is in yellow, saying the server rejected my configuration.
