Hi, @karthik palani
For auto enroll, Is it ok to add the groups either via Group policy, SCCM co-manage collection or Intune (MAM and MDM mobility group in Azure AD)
its best within SCCM to create a pilot device collection and add the devices in there
In Intune, i can see duplicate records with same machine name under Configmgr and Co-Manage category. Is this normal
this is normal and the Configmgr one do go away over time
In Azure AD, the Device is hybrid under Join type but the registered or activity is pending though user logged on. Is there any specific reason please
Intune device registration does take some time to populate the data
