I have a super simple script that I swear I use almost every day, but for some unknown reason my $_. variable is null.
Could someone please spot check it? there is only one column in the CSV I am importing, however it has no header so i don't know if that is what is causing it.
$results = import-csv C:\####\####\####\finddestinguishednamesof.csv | foreach-object {
Get-ADGroup $_. -Properties SamAccountName,DistinguishedName
}
$results | select SamAccountName,DistinguishedName |
Export-Csv C:\Users\laruemi\Desktop\test.csv -NoTypeInformation
I keep getting this error and do not know why.
Get-ADGroup : Cannot validate argument on parameter 'Identity'. The Identity property on the argument is null or empty.
At C:\Users\laruemi\Desktop\getdestinguishedname.ps1:2 char:13
+ Get-ADGroup $_. -Properties SamAccountName,DistinguishedName
+ ~~
+ CategoryInfo : InvalidData: (:) [Get-ADGroup], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationError,Microsoft.ActiveDirectory.Management.Commands.GetADGroup
The list of CSV's I am importing is just a list of SAMAccountNames with no header. i dont think that should cause this error, but it might. Can someone please give me a sanity check?

#{DisplayName=Firstname Lastname} needs to be just 'Firstname Lastname' because get-mailbox -identity '#{DisplayName=Firstname Lastname} won't work.
I've tried using the -replace cmdlet to remove text.
$Olduser = Get-MsolUser -all | Where-Object {$_.BlockCredential -eq $True -and $_.isLicensed -eq $false} | Select-Object displayName,userPrincipalName,BlockCredential,isLicensed
$OldUser | fl *
Using the -replace, I expected that the output will be without '#{DisplayName}'

You are passing an object type with properties to a parameter (-Identity) that expects just a value. As a result, PowerShell converts that object into a string, which results in the value #{DisplayName=Firstname Lastname}. If you access the DisplayName property before passing it into the -Identity parameter, your issue will be resolved.
Get-Mailbox -Identity $OldUser.DisplayName
# Or
$OldUser.DisplayName | Get-Mailbox
You can replicate a similar behavior by typing the following at the console:
[string]$OldUser
Needed to clean up a winmail.dat issue by adding a contact and setting a couple of parameters. All worked as shown, except the command to test that it worked.
Get-MailContact | Select randomemail#email.com | Select -UseMapiRichTextFormat
What is the reason for this failure?
Select-Object : A parameter cannot be found that matches parameter
name 'UseMapiRichTextFormat'. At line:1 char:62 + ... t 1 Select

I think what you actually need is this:
Get-MailContact |
Where-Object {$_.ExternalEmailAddress -eq 'randomemail#email.com'} |
Select-Object -Property UseMapiRichTextFormat
Where-Object limits the result set by comparing each contact's ExternalEmailAddress property and only including the objects that match in the output (which should only be one)
Select-Object limits the output object members to a subset of the original members
I'm trying to create a Powershell script that prints out only certain AD groups from the Folder Permission settings. However for some reason Powershell doesn't recognize StartsWith function.
("C:\folder" | get-acl).Access | ForEach-Object { if (($_.IdentityReference).StartsWith("sl_test")) { continue }; $_ }
When I run this I got errors similar to this for every foreach object:
Method invocation failed because [System.Security.Principal.NTAccount] does not contain a method named 'StartsWith'.
At C:\temp\test.ps1:1 char:56
+ ("C:\folder" | get-acl).Access | ForEach-Object { if (($_.IdentityReference).St ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : MethodNotFound
Any suggestions on how to get this to work?
IdentityReference is a [System.Security.Principal.NTAccount]according to your error message.
But .StartWith is a method on the String type. If you call a method, Powershell does no magic for you, AFAIK.
Try ... ($_.IdentityReference) -match "^sl_test" ..., which should do the implicit string conversion.
If you want the string representation of an IdentityReference (regardless of whether it's and NTAccount object or a SID), you can reference the Value property:
$_.IdentityReference.Value.StartsWith('sl_test')
Try:
Get-Acl -Path "C:\folder" | Select-Object -ExpandProperty Access | Where-Object {$_.IdentityReference -like "sl_test*" }
You can customize the output with an additional | Select-Object -Property XY
Good afternoon,
i've trawled the usual places, here, MS, Scritping guy, Month of lunches etc. to try and answer to my problem. I have a list of users identified by email address and i would like to change their currently blank attributes with the information below.
so:
33 = GLOBAL
34 = 4
35 = SMTP:User#NewDomain.com
Get-ADUser -filter {(Mail -like 'User#OldDomain.com')} -Properties * | Set-ADUser -Replace #{$_.MSExchExtensionAttribute33="GLOBAL"; $_.MSExchExtensionAttribute34="4"; $_.msExchExtensionAttribute35="SMTP:User#NewDomain.com"};
However, when i run the commands i receive this error:
A null key is not allowed in a hash literal.
At line:1 char:98
+ ... roperties * | Set-ADUser -Add #{$_.MSExchExtensionAttribute34="4"; $_ ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (System.Collections.Hashtable:Hashtable) [], RuntimeException
+ FullyQualifiedErrorId : InvalidNullKey
i've used variations on this code in the past without issue to replace attributes that already have values in place so i wonder if that's part of the error.
Any help would be greatly appreciated.
The syntax for changing a (custom) attribute is
Set-ADUser $userName -add #{'MSExchExtensionAttribute33'="Global"}
I hope this solves the issue you're facing.
Like #theo suggested: leave out the $_ variable, and additionally: requesting properties is not needed at all when setting them. So try this, it works on my machine:
Get-ADUser -filter {(Mail -like 'User#OldDomain.com')} |
Set-ADUser -Replace #{MSExchExtensionAttribute33="GLOBAL"; MSExchExtensionAttribute34="4"; msExchExtensionAttribute35="SMTP:User#NewDomain.com"}
I'm learning Powershell and I'm trying to understand why this isn't working. I verified that -Identity accepts pipeline so I'm guessing its the type of value its passing but I don't understand why this doesn't work
Get-ADUser -Identity (Import-Csv .\GROUP.csv)
GROUP.csv is a file on my desktop which contains a list of SIDs. I can read it with no issues when just doing an Import-Csv .\GROUP.csv. Here is the result

On top of that I can use the Get-ADUser -Identity and that works fine.
Why do I get the following when trying piping the one to the other?
Cannot convert 'System.Object[]' to the type 'Microsoft.ActiveDirectory.Management.ADUser' required by parameter 'Identity'.
Specified method is not supported.
At line:1 char:22

+ ~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Get-ADUser], ParameterBindingException
+ FullyQualifiedErrorId : CannotConvertArgument,Microsoft.ActiveDirectory.Management.Commands.GetADUser
The -identity parameter doesn't accept array as input but it accept pipeline input by value than you can do:
Import-Csv .\GROUP.csv | Get-ADUser
If the name of the first column in .csv file is sid then you can try this option too
(Import-CSV .\Group.csv) | foreach-object { get-aduser -Identity $_.sid }
