Hi @Jackson, Chris
Welcome to our forum!
Yes, here are a few methods you may refer to:
- Use Sensitivity Labels: Apply a sensitivity label that assigns either the "Encrypt-Only" or "Do Not Forward" protection option to your email. This restricts access to only those specified in the To, Cc, or Bcc fields. More information: Prevent mailbox delegates from reading protected messages - Outlook | Microsoft Learn
- Information Rights Management (IRM): Use IRM to protect your email. This can prevent delegates from reading protected messages. You can configure this in Outlook by selecting "Options" > "Permissions" and choosing the appropriate restriction.
- Move Confidential Emails to a Separate Folder: Use a rule to automatically move emails marked as confidential to a folder that your delegates do not have permission to access.
- PowerShell Command: If you have administrative access, you can use the
Set-MailboxIRMAccess
cmdlet to block specific delegates from accessing IRM-protected messages. For example:
This command prevents the specified delegate from reading IRM-protected messages in your mailbox.
