Bulk delete Outlook profiles from a shared computer

There is this post I found, I guess this should be helpful for you in removing the profiles from the system, this is a PowerShell script so you can easily modify it according to your environment and need.

if($process=(get-process 'outlook' -ErrorAction SilentlyContinue))
{
    Write-Host "Outlook is running so close it.." -ForegroundColor Green
    kill($process)
    Write-Host "Outlook is stopped " -ForegroundColor Green
}

$reg="HKCU:\Software\Microsoft\Office\15.0\Outlook\Profiles"
$child=(Get-ChildItem -Path $reg).name
foreach($item in $child)
{
    Remove-item -Path registry::$item -Recurse #-ErrorAction Inquire -WhatIf
}

Select allOpen in new window

Don't have a script for removing profiles for all users but for sake of accuracy, assuming this involves OL'2010 (or earlier) - the registry location for each individual user is

HKCU\Software\Microsoft\Windows NT\Windows Messaging SubSystem\Profiles

Select allOpen in new window

All you need to do is rename \Windows Messaging Subsystem to something else so that OL'2013/'2016 doesn't pick up any of the old profiles.

Not clear what exactly you mean by Office 365 since that's OL'2016 (current version) so if you already have OL'2013/'2016 installed then the reg location mentioned by Sunil would apply

HKCU:\Software\Microsoft\Office\##.0\Outlook\Profiles

Select allOpen in new window

I meant OL 2016 yes,

this location does seem to only contain the current user and not all users profiles

HKCU:\Software\Microsoft\Office\##.0\Outlook\Profiles

when I log in as another user and try to find the other user's Outlook profile reg key with the unique name I created, it cannot be found. The user is a local admin.

Any idea?

Not entirely clear about what the above means, specifically - log in as "another user" and try to find the "other user's" profile so would this be translated as "login is User1" and try to find the profile(s) for "User2"? If yes, you wouldn't - HKCU is for the logged in user.

I know but I searched the entire registry for the other user's Profile which has a unique name and it cannot be found thus cannot be deleted

we are trying to delete all Outlook profiles for all users

Thank you

thanks!
