Hi @Efff dd ,
I think you could go ADUC and check this group, group name, e-mail address.
Or doing it in EMS:
Get-DistributionGroup DP1 | FL *Name*
Like Andy said, i think you don't have to worry about it as you could modify these parameters manually or recreate the group.
Get-DistributionGroup DP1 | Foreach {Set-DistributionGroup $_.Name -SamAccountName $_.Name -DisplayName $_.Name}
Regards
Lou
