Pls, help...
I need to fill a considerable quantity of lists with a considerable quantity of new members. The initial information in a format "List Name - the list of members"
How Update-DistributionGroupMember to force to understand the list of members?

Update-DistributionGroupMember -Identity Dlist1 -Members Members1, Members2, Members3 - work fine, but I have many dlist and many members...
Import-Csv Dlist.csv |  foreach { Update-DistributionGroupMember -Identity $_.Alias -Members $_.Members } - dont work.....

Thanks

I have not tested this in 2010. Please try this.

Create your CSV file with DL names in one column and members in another column in the format "Member1","Member2"... with headings DL and Members

Import-Csv Dlist.csv | foreach { Update-DistributionGroupMember -Identity $_.Alias -Members $_.Members }. Let me know if you receive any errors.
