Office365 Quarantine

If you are wanting to delete Email messages from Office 365 Quarantine using the web portal, it allows you to remove 100 messages at a time.  Selecting 100 at a time to be deleted is not an efficient use of time.

Below is a quick way you can delete Quarantine Email messages from Office 365 using the Windows Powershell.  

  1. Open Powershell as Administrator
  2. Run the following commands;

    $UserCredential = Get-Credential

    Set-ExecutionPolicy Unrestricted

    $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection

    Import-PSSession $Session
    Office 365 Quarantine

  3. As we are going to be using Exchange commands, Install & Import the Exchange powershell modules

    Install-Module -name ExchangeOnlineManagement

    Import-Module ExchangeOnlineManagement
    import exchange modules into powershell

  4. Almost time to delete the Emails, type the following to check what the Quarantine Contains

    Get-QuarantineMessage

    check office365 email quarantine

  5. Ok lets nuke the Email Messages, type:
    $ids = Get-QuarantineMessage | select -ExpandProperty Identity; Delete-QuarantineMessage -Identities $ids -Identity 000 -Confirm:$false

    delete all emails from quarantine

  6. Check that the Quarantine is empty:
    Get-QuarantineMessage

    If it still returns a list of Email Messages, run the cmd in Step5 again.

Yes I know you are saying ‘Hey I thought I could delete ALL the emails in one go’.  Well sorry you are still limited to 100.  Just continue to run the cmd in Step5.  But hey, it is still better then having to select 100 messages at a time.
