Hello,

I would like to rename a multiple groups at once.  Is there a power shell command that I can use? I saw this command online, but it looks like this only updates one group at a time. https://technet.microsoft.com/en-us/library/bb124955(v=exchg.150).aspx

Set-DistributionGroup -Identity "Accounting" -DisplayName "Accounting Group"

I have about 20 groups and the first portion of their names begins with ABC_ , and I would like to change that to DEF (i.e. ABC_Helpdesk to DEF_Helpdesk...).  Than

It's about time for you to learn how to do some PowerShell scripting.

We are using DirSync to update our AD attributes, the changes has to be done on AD and not on Exchange Online.  Yes, Ed.  so far, I am learning a lot on Power Shell, thanks. Do you have any input?

Create a CSV file name test.csv. Below are the values

old,new

ABC_Helpdesk,DEF_helpdesk

Copy below code and save as set.ps1

$name = import-csv test.csv

foreach ($b in $name)

{

$o = $o1.old

$n = $n1.new

Set-DistributionGroup -Identity "$o" -DisplayName "$n"

}

Run the .ps1 file.

Hi,

Use this command to export all DL information to CSV file.

Get-DistributionGroup | select-object identity,displayname | export-csv C:\DL.csv

Then open this csv file and edit the displayname to what you want, run the following command to set.

Import-Csv "C:\DL.csv" | ForEach-Object{ Set-DistributionGroup Identity $_.Identity DisplayName $_.DisplayName}

Best Regards.

Thank you Lynn, I'll give this a try.

Thank you Vishwanath, I'll give this a try.

Hi Lyn,

If I get all the DL information on the CSV file, let's say I have about 700 groups on the list, but I only need 25 groups to work on, can I then remove the other 625 groups? Is it safe to do that, then after saving my changes, export it to AD? Thanks.

Hi Vishwanath,

I just want to understand/learn your codes (in bold):

$name = import-csv test.csv

foreach ($b in $name) = what is this value means?

{

$o = $o1.old = $o1 why are we using this code before the .old? 

$n = $n1.new =$n1 why are we using this code before the .new?

Set-DistributionGroup -Identity "$o" -DisplayName "$n"

}

Thanks.

Hi,

Yes, it's safe to remove the other 625 groups.

I prefer extracting these 25 groups to another CSV file.

Best Regards.
