Looking for a quick PS script to pre-pend all my distribution groups display names and aliases with 'UB_'

Right now I'm going through and manually editing each one, but I've got over 200 of them.

Get-DistributionGroup -ResultSize Unlimited | % { $nuname = "UB_" + $_ ; Set-DistributionGroup -Identity $_ -Name $nuname -IgnoreNamingPolicy}

Open in new window


Something like above should work.

If you have a list of groups already then you can pipe in from a text file or csv.

Import-Csv blah.csv | %  { $nuname = "UB_" + $_.Name; Set-DistributionGroup -Identity $_.Name -Name $nuname -IgnoreNamingPolicy }

Open in new window


This assumes your csv has a column header named name, eg:

Name
DG1
DG2
DG3

Oh yeah duh.. $_.columnName.

Worked like a champ!

Now is $nuname a specific property field for an object?

$nuname is the variable we create to hold the value of the new name

$nuname (variable name )

"UB_" + $_.Name; (variable value)

We combine the two strings "UB_" and whatever the value is of the current name to make the new string $nuname which we pass into the command.
