The goal of the script is to run and add all users with a specific job title to an AzureAD Group. I've tested the variable and it grab the right people and will display if I write the variable to the screen.
The error message I get states "ADD-AzureADGroupMember : Cannot convert 'System.Object[]' to the type 'System.String' required by parameter.
#Grab all users with the job title IT Support Technician
$User = (Get-AzureADUser -All $true |
Where-Object -FilterScript {$_.JobTitle -eq "IT Support Technician"}).ObjectId
#Grab the ObjectID of the AzureADGroup
$Branch = (Get-AzureADGroup -SearchString "Test SG").ObjectId
#Add each of the Users to the AzureADGroup
$User | ForEach-Object {
Add-AzureADGroupMember -ObjectId $Branch -RefObjectId $User
}
You're iterating over $user then trying to add all users within your Foreach-Object loop.
To reference the current pipeline item you can use $_ or $PSItem
$User | ForEach-Object {
Add-AzureADGroupMember -ObjectId $Branch -RefObjectId $_
}
