Thunderbird suddenly stopped sending from OUTLOOK
Thunderbird has worked flawlessly for my Outlook account as well as several IMAP accounts now for the last 2 days, it refuses to send. CY4PEPF0000EE36.mail.protection.outlook.com gave this error: Requested action not taken: mailbox unavailable (S2017062302).
Refuses to send ONLY from Outlook.
