Unable to bulk add members to a Distribution Group

Hello,

I have a CSV file c:\users.csv which has list of UPN. The format looks like this:

UPN
user1@mydomain.com
user2@mydomain.com
.....

I am able to use the below command to add members to an Office 365 Group:
Import-CSV "C:\users.csv" | % { Add-UnifiedGroupLinks -Identity "Office 365 testgroup" -LinkType Member -Links $_.UPN }

However, I am getting an error if I specify a Distribution Group I create in the O365 portal Exchange admin console.
"This operation couldnt be performed because object 'testgroup' couldn't be found on ......outlook.com.....

What is the main different between the two type of groups? How do I fix the issue?

Thanks.

Thanks, Adam Brown....

I am trying import-csv "C:\users.csv" | foreach {add-distributiongroupmember -identity test -member $_.UPN} and I am still getting error - The operation couldn't be performed because 'TEST' matches multiple entries...

Test is a distribution group. My users.csv file remains the same

UPN
user1@mydomain.com
user2@mydomain.com
.....

Please advise again.

Thanks.

The problem is with the group, not the members. Find a better identity for the group.

Get-DistributionGroup -Identity 'Test'

Open in new window

The distribution group was created in the Exchange Admin console - new>new distribution group.

I tried Get-DistributionGroup -Identity 'Test'. I am getting this:

Something not quite right there by the looks of it, might need a bit of a look into whether or not that group is working.

see if this shows up:

Get-Recipient Test -RecipientTypeDetails GroupMailbox

Open in new window

for more info refer: https://social.technet.microsoft.com/Forums/lync/en-US/5e33627d-aaaa-43f6-a8a3-38c6d63ab4d0/cant-find-phantom-email-address-on-office-365-tenancy?forum=onlineservicesexchange
this could get you to the right direction

Can you check what is the group type of the group you created. Go to Exchange Admin Center> Recipients> Groups. The group type should be "Distribution group" and not "Office 365 Group".
