Good evening everybody,

Is there any powershell expert who could help me to build a powershell script based on excel file (attached) in order to create user accounts and mailboxes.

Some basic rules are :
samacountname < 20 characters : 8 first from first name "." 10 first characters from last name without spaces

AD account has to be activated at the end of the script.
Please find attached an example of excel file.

Regards,

Julien

I'm going to assume a couple of things.  You will...

  1. Be providing the proper naming rules in the CSV file based on your requirements;
  2. Remove the spaces from the headers;
  3. Convert (or save) the Excel file as a CSV file; and
  4. Be running the command from the Exchange server with the RSAT-ADDS feature installed.

This is what I feel the CSV file should look like.  Notice I removed the password column and changed the OU path syntax.  The passwords, IMO, should be passed inline as a secure string instead of in clear text (which typically will not work anyway).

FirstName,LastName,DisplayName,SamAccountName,UPN,ADOUPath,MemberOf1,MemberOf2,MemberOf3,MailboxDatabase,Alias
Jake,IRVIN,FSOCIETY User1,jake.irvin,jake.irvin@fs01.com,"FSOCIETY.COM/Users",Printers_all,dist_list_all,dist_list_fsociety,DATABASE_1,jake.irvin

Open in new window


Assuming those things, this should get you in the right direction...

Run this command, and enter a password when prompted...

$MyPassword = Read-Host "Enter Password:" -AsSecureString

Open in new window


Run this script to create users with mailboxes, and then add them to groups...

Import-Csv "C:\ADUsers.csv" | ForEach-Object { 
     
     New-Mailbox -UserPrincipalName $_.UPN -Alias $_.Alias -saMAccountName $_.SamAccountName -FirstName $_.FirstName -LastName $_.LastName -DisplayName $_.DisplayName -OrganizationalUnit $_.ADOUPath -Database $_.MailboxDatabase -Password $MyPassword -ResetPasswordOnNextLogon $true 
     
     Add-DistributionGroupMember -Identity $_.MemberOf1 -Member $_.Alias -BypassSecurityGroupManagerCheck
     
     Add-DistributionGroupMember -Identity $_.MemberOf2 -Member $_.Alias -BypassSecurityGroupManagerCheck
     
     Add-DistributionGroupMember -Identity $_.MemberOf3 -Member $_.Alias -BypassSecurityGroupManagerCheck
     
}

Hope that helps.

I wasn't near my lab yesterday and needed to test the script I provided to ensure I gave you something that worked.  After testing this morning, there is one slight modification that had to be made.  New-Mailbox requires the Name parameter.  The values for the name parameter come from the DisplayName column.  Also, the associated AD user created will be prompted to update their password at first logon.  The new script is below...

$MyPassword = Read-Host "Enter Password" -AsSecureString

Import-Csv "C:\Scripts\MyNewUsers.csv" | ForEach-Object { 
     
     New-Mailbox -Name $_.DisplayName -UserPrincipalName $_.UPN -Alias $_.Alias -saMAccountName $_.SamAccountName -FirstName $_.FirstName -LastName $_.LastName -DisplayName $_.DisplayName -OrganizationalUnit $_.ADOUPath -Database $_.MailboxDatabase -Password $MyPassword -ResetPasswordOnNextLogon $true 
     
     Add-DistributionGroupMember -Identity $_.MemberOf1 -Member $_.Alias -BypassSecurityGroupManagerCheck
     
     Add-DistributionGroupMember -Identity $_.MemberOf2 -Member $_.Alias -BypassSecurityGroupManagerCheck
     
     Add-DistributionGroupMember -Identity $_.MemberOf3 -Member $_.Alias -BypassSecurityGroupManagerCheck
     
}
