PowerShell 7.3 - Difficulty with Retrieving AD User Attributes in a Large Domain Environment
I recently switched to I'm trying to configure I tried several approaches but none seem to work. I'm working with PowerShell 7.3 and attempting to retrieve specific attributes of users from Active Directory in a large domain environment. My script uses `Get-ADUser`, but I'm working with performance optimization and timeouts when querying a substantial number of users. Here’s my current implementation: ```powershell $users = Get-ADUser -Filter * -Property DisplayName, EmailAddress, Title foreach ($user in $users) { Write-Output "Name: $($user.DisplayName), Email: $($user.EmailAddress), Title: $($user.Title)" } ``` This script works fine for smaller domains, but it takes an exceedingly long time to complete in our environment, sometimes even throwing a timeout behavior: "Get-ADUser : The operation has timed out." I've tried using the `-ResultSetSize` and `-SearchBase` parameters to limit the number of records returned, but it doesn't seem to improve the execution time significantly. For instance: ```powershell $users = Get-ADUser -Filter * -Property DisplayName, EmailAddress, Title -ResultSetSize 1000 -SearchBase "OU=Users,DC=example,DC=com" ``` I also considered using `Get-ADUser` with paging, but I'm not quite sure how to implement that correctly. Could someone provide guidance on how to optimize this query for better performance or suggest an alternative approach to avoid timeouts while retrieving user attributes? Any pointers on best practices for working with large datasets in PowerShell would also be appreciated. Am I missing something obvious? Any ideas how to fix this? Is there a simpler solution I'm overlooking?
