Received an email from Microsoft telling me as of December 1st, 2022 they will no longer support TLS 1.0 and 1.1 for IMAP Servers for email clients. I looked in the Thunderbird Configuration Editor (security.tls.version.min) and it's set to a minimum of 3.

From Microsoft: Starting on December 01, 2022, Office 365 will begin retiring Transport Layer Security (TLS) 1.0 and 1.1 for POP3 and IMAP4. TLS is a standard protocol used to provide secure web communications for POP3 and IMAP4. POP3 and IMAP4 are the client/server protocols for receiving emails. We will enforce TLS 1.2 moving forward to provide enhanced encryption and help ensure your emails are received more securely. We have already disabled TLS 1.0 and 1.1 for most Microsoft 365 services in the worldwide environment. https://learn.microsoft.com/en-us/microsoft-365/compliance/tls-1.0-and-1.1-deprecation-for-office-365?view=o365-worldwide&ocid=cmmvcsuhj3z

I'm using Windows 11 which should be fine, but if Thunderbird is set to TLS Minimum 3 will it still use the required 1.2 for IMAP Servers? I'm currently using IMAP Server outlook.office365.com for a msn.com email address. Will I still be able to get my email in Thunderbird after this change?
