Allow a device to access 
Microsoft ActiveSync

If 
BlackBerry UEM
 cannot obtain an 
Exchange ActiveSync
 ID from a device, it is not added to the allowed list for 
Microsoft Exchange
. You can manually add these devices to the allowed list from the Restricted 
Exchange ActiveSync
 devices list. For example, if an 
Android
 device is activated using the MDM activation type, 
BlackBerry UEM
 is not able to obtain an 
Exchange ActiveSync
 ID and you must manually whitelist the device in the Restricted 
Exchange ActiveSync
 devices list.
  1. On the menu bar, click 
    Users > Exchange gatekeeping
    .
  2. Search for a device.
  3. In the 
    Action
     column, click The Allow icon.
