PowerShell - Import all .PST files in directory

by Jim 18. October 2011 18:56

Thie script below will impor all the .PST in a directory.  NOTE: You MUST have the .PST name match the alias in the domain.

Get-ChildItem \\server\share\*.pst | foreach { $user = $_.BaseName; New-MailboxImportRequest -Mailbox $user -FilePath \\server\share\$user.pst -BadItemLimit 50 }



PowerShell - Create AD Groups then Populate Them from CSV

by Jim 16. October 2011 17:57

In my previous post, I explained how to export a .CSV for each group in an OU.  This gives you a .CSV for each group which is named the same as the group name.

  • Some Group 1.csv
  • Some Group 2.csv
  • Some Group 3.csv
  • Some Group N.csv

Now, I need to create those Groups in a new AD.  Here is the script that I used:

Get-ChildItem | foreach { echo $_.Basename } | ForEach-Object { dsadd group -scope u "cn=$_,OU=Groups,OU=Some OU,DC=SubDomain,DC=Domain,DC=TLD" }

This script calls the program DSADD and passes it the correct name (minus the .csv) which is then used to create the Groups.

Next, we run a similar script that walks through those same .CSV's and adds the users to the group with the same name as the .CSV.

Get-ChildItem | foreach { $GN = $_.BaseName; Import-Csv $_ } | foreach { Add-ADGroupMember -Identity $GN -Members $_.SamAccountName }

This works wonderfully well if the column titled SamAccountName has the correct usernames in it.

PowerShell - Export Group Members to CSV

by Jim Bouse 16. October 2011 16:52

This script will export a .CSV for each group in an OU.  The CSV will be named the same as the group name.

Use this code on an Exchange Server:

Get-Group -OrganizationalUnit "Some OU" | ForEach-Object { Get-Group -Identity $_.Name | ForEach { $_.Members } | Get-User | Export-Csv ($_.Name + '.csv') }


Use this code on an machine with Import-Module ActiveDirectory loaded:

Get-ADGroup -OrganizationalUnit "Some OU" | ForEach-Object { Get-ADGroup -Identity $_.Name | ForEach { $_.Members } | Get-ADUser | Export-Csv ($_.Name + '.csv') }

* Greg Martin suggested I clear this up...  Thanks!

PowerShell - Add Users to Group from CSV

by Jim 16. October 2011 14:56

I needed to add users to groups by PowerShell and was having trouble finding examples how to do it.  Here is how I figured it out.

First, you need a CSV of the users's logon names.  My list came from the CSV from:

Get-DistributionGroupMember -Identity 'Some List' | Export-Csv 'list.csv'

The list generated above consisted of alot of fields.  The only one I am interested in for this use is "Alias".  Once I had the list generated from my old AD, I then ran:

Import-Csv 'list.csv' | ForEach-Object { Add-ADGroupMember -Identity "Some New Group Name" -Members $_.Alias }

Remember the script above needs to be a single line.  I had to break it apart so it will fit in the blog format.  It worked like a charm.

PowerShell - Export Mailbox Users to CSV

by Jim 16. October 2011 13:03

This script exports users from an OU to a CSV that can be used by other scripts.  I had to move hundreds of users from one domain to another and modify some user properties during the process.  A CSV file allows you to open the file in Excel and edit the fields as needed.  You can take the output of this script and use it to create uses in a new domain with this script.

Get-Mailbox -OrganizationalUnit "User OU" | Export-Csv -f User_Mailboxes.csv

Export details for all mailboxes for user in OU.txt (76.00 bytes)

PowerShell - Create Users from CSV

by Jim 16. October 2011 11:23

This script creates users via Powershell.  I had to create 500 users in a new Active Directory domain that I had previously exported from an old domain.  This script can be run from the command line in PowerShell.  I have attached a .TXT file with the script if you would like to download it.

You will need a .CSV file with the following columns:

  • Alias
  • UPN
  • Name
  • DisplayName
  • FirstName
  • LastName
  • OU

Import-Csv 'Users.csv' | ForEach-Object { New-ADUser -SamAccountName $_.Alias -UserPrincipalName $_.UPN -Name $_.Name -DisplayName $_.displayname -GivenName $_.FirstName -Surname $_.LastName -Path $_.OU -AccountPassword (ConvertTo-SecureString "Some!Password" -AsPlainText -Force) -Enabled $true -PasswordNeverExpires $false -PassThru } > Import.log

Create users from CSV.txt (349.00 bytes)
