Cannot modify settings in Samsung Email client

Last updated July 26th, 2023



  • Knox Platform for Enterprise (KPE)
  • Android Enterprise (AE) Device Owner (DO) mode
  • Samsung Email


On some AE DO devices with the policy “Allow adding and removing accounts” disabled in the UEM, an issue is observed where the user cannot modify server email settings. These settings include:

  • Email signature
  • Out of office notifications
  • Sync frequency
  • Sync period
  • Calendar sync period

When the user attempts to change these email settings, the following error message appears:

Access to email settings blocked by AFW


When an IT admin configures a policy to prevent modification to an email account, the user is unable to change any settings in the Samsung Email client.


This behavior is by design, to prevent the user from making unwanted changes in the Email client.
