Active sync device getting blocked automatically

Few of my user’s active sync devices are getting blocked automatically.

 Created a test active sync mailbox policy and assigned the same to the affected users still no help then checked the user’s device ID’s and added the device in the allowed device list again the devices got blocked n 24 hours and started appearing in blocked devices.

Checked the details and found the below reason for the block:

Device model:

Outlook for iOS and Android

Device type:

Outlook

Device ID:

 

Device OS:

OutlookBasicAuth

Device user agent:

Outlook-iOS-Android/1.0

Device IMEI:

 

Exchange ActiveSync version:

14.1

Device access state:

Blocked

Device access state reason:

Individual

 

My users are managed by MDM Intune hence checked for any conditional access policy but could not find any.

What could be the other reason the devices are getting blocked automatically even after adding the device ID’s in the allowed list?
