Im am currently looking to switch TLS setting from 1.0 to 1.2 on a WC7830 but can not find any setting. I know that there was a firmware update for the 7845 to get this working and implement the TLS settings into the Security - Encryption Menu.
The current installed Firmware is Version 073.010.075.34540 which is the latest to download from the support portal.
I have verified with message tracking that the device is currently using TLS 1.0 sending emails with scanned documents to Office 365. Microsoft will switch off TLS 1.0 and 1.1 and we need to get it running on TLS 1.2.
