Subject: Not Receiving Expected Emails? Check Your Mimecast Held Emails Folder

If you are expecting an email but have not received it, it may have been held by Mimecast as potential spam or for other security reasons. You can check your Mimecast held emails folder to see if the message is there.

There are two primary ways to access your Mimecast held emails:

  1. Via the Mimecast Website:

    • Go to mimecast.com.
    • Log in using your corporate email address and password.
    • Once logged in, navigate to the "On Hold Messages" or "Personal Portal" section to review any emails that have been quarantined. From there, you can release legitimate emails to your inbox.
  2. Using the Mimecast Add-in for Outlook:

    • If you have the Mimecast add-in installed in Microsoft Outlook, you can usually access your held emails directly from Outlook.
    • Look for a "Mimecast" tab or section in your Outlook ribbon.
    • Within the Mimecast add-in, there should be an option to view "On Hold Messages" or access your "Personal Portal," which will display any emails currently being held.

If you find the email in your Mimecast held emails, you can typically release it to your inbox directly from the Mimecast portal or add-in. If you continue to experience issues or cannot locate an expected email after checking Mimecast, please contact the IT support team for further assistance.
