From all I've read on this forum TB supports (and has for a long time) TLS 1.2. When I got this message in the inbox of my *@hotmail acct, I got confused. I use TB 102.4.2 (32-bit) for all my email accounts including this *@hotmail POP account. I don't want to use IMAP. Here's what their message said: "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." I don't know how this hotmail account could have been accessed by someone or something using TLS 1.0 or 1.1 since I only use TB to access my hotmail. I wonder if Microsoft is just sending this to anyone with a hotmail account??
