Target Audience - non-existent membership Group

While working with User Profiles Service and Target Audience I noticed that members are not showing up in Audiences. There are the possible areas to look for reasons -

- Check group is present in AD.
- Look for Group with same name (duplicate group).
- Check service account permission on Active Directory (OU).
- Check the User Profile Synchronization connection. Make sure Sync connection includes the OU's where groups are located.
 UPApp > Syncronization> Configure Synchronization Settings > Option "Users & groups" is selected, run a Full Sync
- If Full sync is not working then Check User Profile Synchronization Service. (Stop and Start with correct Credential to fix any FIM issues - IISreset required after User Profile Synchronization Service started)
- Compile the audiences after Full Sync.
- Check if Audience shows Users in view membership.
- Check Audience Rules if Audience rule throws error.
- Check Groups are present in UPA "Profile DB" post Full Sync.

Run the following queries against Profile DB of the to see if group is present or not

Select * from MemberGroup (nolock) where AllWebsSynchID is NULL -- It should fetch all AD groups
Select * from MemberGroup (nolock) where AllWebsSynchID is NULL and DisplayName like '%group name%'

Also if you are uploading audiences using PowerShell Script then make sure you are using Active Directory Group's full path in Value option in reverse hierarchy not just Group Name.

<Rule Property='DL' Operator='Member of' Value='CN=GroupName,OU=Groups,OU=ABC,DC=Domain,DC=com' />
