Knox Platform for Enterprise (KPE)
On a device with a work profile, emails cannot be sent or received when the Data Saver feature is enabled on the personal side.
There is a bug preventing the Email app from connecting to a proxy server through the VPN when Data Saver is enabled.
The Knox team has identified a fix, scheduled for an upcoming firmware update.
If you are encountering this error without a VPN, enable data for the Email app in the work profile by following the steps below:
- On your device, navigate to Settings > Workspace > Apps > Email > Mobile data.
- Enable Allow app while Data saver on.
You can then send and receive emails without fully disabling Data Saver.
