I'm getting the error when synchronising outlook email accounts that states "The current operation on 'Inbox' did not succeed. The mail server for account- Outlook responded: User is authenticated but not connected. The email account was synching well until I updated recently to v128.4.4esr. I searched around online and have tried the following suggestions: - network.dns.disableIPv6 -> true - delete outlook mail account and re-connect - clear startup cache
