We want to configure Delete inactive Client automatically 25 days in our SEPM console, reason for saving SEP client license.

Please Clear below Query

If some of user laptop is out of network during period and again laptop connect network. As per my understanding client will show again SEPM console.

1) Does client will move correct group or default group?

2) Can we track how many system /or host name has been removed from SEPM console after this setting.
 

When user will be online it automatically reflect on Server.

Client will reflect to the default group.

No you not be able to track which of the hostname is removed but you can check the what count of license is free. You can check the license count before the applied and check again after it process

2) Can we track how many system /or host name has been removed from SEPM console after this setting.

No you can't track which client are removed for SEPM database,before applied policy your export all client data and match host name client data after applied delete inactive data policy.

If you have AD integration - does the delete inactive clients affect just the non-AD objects or the AD objects as well? Objects stay by the client information gets cleaned/removed?

If NO AD sync, it will return to default group upon check in.

There is no way to track which client was deleted.
