Delete email from all mailboxes office 365

A bold request!

To delete an email from all mailboxes in Office 365, you'll need to use PowerShell and the Exchange Online PowerShell module. Here's a step-by-step guide:

Prerequisites:

  1. You need to have the Exchange Online PowerShell module installed on your machine. You can install it by running the following command: Install-Module -Name ExchangeOnline
  2. You need to have the necessary permissions to manage Exchange Online. You can check your permissions by running the command: Get-OrganizationConfig | fl
  3. You need to have the email address of the email you want to delete.

Step 1: Connect to Exchange Online

Open PowerShell and run the following command to connect to Exchange Online:

Connect-ExchangeOnline -UserPrincipalName <your_username> -ShowProgress $true

Replace <your_username> with your Office 365 username.

Step 2: Get the email address

Run the following command to get the email address of the email you want to delete:

$emailAddress = "[email protected]"

Replace [email protected] with the actual email address you want to delete.

Step 3: Delete the email from all mailboxes

Run the following command to delete the email from all mailboxes:

Get-Mailbox -ResultSize Unlimited | ForEach-Object { Search-Mailbox -Identity $_.Identity -SearchQuery "subject:'$emailAddress'" -DeleteContent -Force }

This command uses the Get-Mailbox cmdlet to retrieve all mailboxes in the organization, and then uses the ForEach-Object cmdlet to iterate through the results. For each mailbox, it uses the Search-Mailbox cmdlet to search for the email with the specified subject (in this case, the email address you provided). The -DeleteContent parameter deletes the email, and the -Force parameter forces the deletion without prompting for confirmation.

Step 4: Confirm the deletion

After running the command, you'll be prompted to confirm the deletion. Type Y and press Enter to confirm.
