IMPORTANT NOTICE - Changes to your email account - hotmail -live -msn - outlook

 

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.

When this will happen

December 01, 2022

What do I need to do?

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. You can find out technical details on how to upgrade in this article: Disabling TLS 1.0 and 1.1 for Microsoft 365 - Microsoft Purview (compliance) | Microsoft Docs

What if I cannot update/upgrade?

If you cannot update/upgrade your legacy client, we provide an opt-in endpoint for you to continue connecting with TLS 1.0/1.1. Your legacy clients must be configured to pop-legacy.office365.com for POP3 and imap-legacy.office365.com for IMAP4. Using legacy versions of TLS is not as secure as TLS 1.2, however, so we recommend you update and use TLS 1.2.
