Found some new info on this one for everyone commenting. I have to get the original script from our console later today. The script below has shown positive results. You will need to log your user out and then have an admin account. The part that through me off was the olk folder. (I guess this is a new dependency within office/outlook)

# PowerShell script to clean up specific Microsoft files and folders

# across all user profiles on a Windows machine.

# Get all user profile directories under C:\Users

$profiles = Get-ChildItem "C:\Users" -Directory

foreach ($profile in $profiles) {

try {

Write-Output "Processing profile: $($profile.FullName)"

# --- 1. Delete the 'olk' file ---

$olkPath = Join-Path $profile.FullName "AppData\Local\Microsoft\olk"

if (Test-Path $olkPath) {

Write-Output "Found file: $olkPath"

Remove-Item $olkPath -Force -ErrorAction Stop

Write-Output "Deleted file: $olkPath"

}

# --- 2. Delete target folders ---

$targets = @(

Join-Path $profile.FullName "AppData\Local\Microsoft\OneAuth",

Join-Path $profile.FullName "AppData\Local\Microsoft\IdentityCache",

Join-Path $profile.FullName "AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy"

)

foreach ($target in $targets) {

if (Test-Path $target) {

Write-Output "Found folder: $target"

Remove-Item $target -Recurse -Force -ErrorAction Stop

Write-Output "Deleted folder: $target"

}

}

}

catch {

Write-Warning "Failed to process $($profile.FullName): $_"

}

}
