Live@EDU Environment - Exchange 2010 Afternoon, I am creating a large amount of distribution groups, some have members and some will only have the owner initially. Is there any way to pass a $null imported value in this scenario so that the cmdlet completes successfully but does not have a value for the -Members attribute? Import-Csv C:\PowerShell\resource-test.csv | foreach { New-DistributionGroup -Name $_.GroupName -Alias $_.GroupAlias -CopyOwnerToMember -ManagedBy $_.OwnerPrimarySMTP -Members $_.MembersPrimarySMTP.split(",") } Couldn't find object "$null". Please make sure that it was spelled correctly or specify a different object. + CategoryInfo : NotSpecified: (0:Int32) [New-DistributionGroup], ManagementObjectNotFoundException + FullyQualifiedErrorId : 3E963AFD,Microsoft.Exchange.Management.RecipientTasks.NewDistributionGroup If I run it by itself, it completes without any issue. New-DistributionGroup -Name "OCIS Test Resource" -Alias grp.OCIS.test_resource -CopyOwnerToMember -ManagedBy janestaff@uga.edu -Members $null Thank you for your assistance. I apologize if this has been asked already but I was unable to find it. Rachel

You can try something like this (I haven't tested it): $Members = $_.MembersPrimarySMTP.split(",") If ($Members.length -eq 0) {$Members = $Null} Import-Csv C:\PowerShell\resource-test.csv | foreach { New-DistributionGroup -Name $_.GroupName -Alias $_.GroupAlias -CopyOwnerToMember -ManagedBy $_.OwnerPrimarySMTP -Members $Members } Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

IOW, is the "MembersPrimarySMTP" an object or is it not? It might be a better idea to only execute the split if the "$_.MembersPrimarySMTP -is [object]". Maybe something like this? foreach {if ($_.MembersPrimarySMTP -is [object]){$m = $_.MembersPrimarySMTP.split(",");new-distributionsgroup ... -Members $m} else {new-distributiongroup ...}} --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
