I have been notified by Microsoft of the following change and I would like to know how it will impact my ability to receive/send mail via my Thunderbird "@msn" account whose IMAP mail server is "outlook.office365.com"

Starting on December 01, 2022, Office 365 will begin retiring Transport Layer Security (TLS) 1.0 and 1.1 for POP3 and IMAP4. Our records show that your email account has recently been accessed with POP3/IMAP4 through TLS 1.0 or 1.1. POP3 and IMAP4 will not be able to connect with TLS 1.0 and 1.1 starting on December 01, 2022. You will not be able to receive emails with POP3/IMAP4 protocol after that. To continue accessing your email account using POP3 or IMAP4, please upgrade/update your client to support TLS 1.2. Your emails will not be removed, but you cannot access them without upgrading your client.

Thank you for any assistance.

Thunderbird has supported TLS 1.2 for well over a year and your continued access to your account is safe.
