Why Is This Important?
TLS version 1.2 provides a secure connection. This update means all email server connections using TLS 1.0 and 1.1 will need to be updated to TLS 1.2. Non-secure connections will no longer be supported.
If your email application or software is not configured with a secure connection, you may experience an interruption with your email service.
What To Do
This section explains the steps you can take to ensure you do not experience any interruptions due to this update.
- First, check if your email application or operating system is supported by reviewing the supported email applications and operating systems.

- Outgoing Server (SMTP) requires authentication: Yes
