- Monitor Suspicious Activities:
Get-MailboxAuditBypassAssociation -Identity "[email protected]"
What Undercode Say:
Microsoft’s update finally brings better control over shared mailboxes, reducing IT overhead. However, admins should enforce strict permission policies to prevent misuse. Automation via PowerShell remains key for large-scale management.
Expected Output:
- IT Admins: Use PowerShell for bulk mailbox management.
- End Users: Enjoy seamless integration with Outlook’s new UI.
- Security Teams: Monitor access logs to prevent unauthorized changes.
Prediction:
As shared mailboxes become easier to manage, expect a rise in adoption—but also increased phishing attempts targeting shared accounts. Enhanced security measures will be crucial.
