Use of TLS 1.0/1.1

TLS 1.0/1.1 will reach end of support by Microsoft by end of June, 2020. At our company we run IFS 9 UPD 1.

We are using IFS functionality to send emails via IFSCONNECT mail sender, we don´t have right now TLS checked

We want to understand:

1. The impact in the email sending functionality from IFS, we don´t know if Office365 will be blocking this feature or we will have any change when current TLS versions become unsupported
2. If we can install TLS 1.2 in our current version

Thank you,
