To address the issue, do the following:

  1. Verify if the email address is an actual valid recipient in your organization.
  2. Log on to the TMEMS web console.
  3. Go to Administration > Under Other Settings > Directory Management.
  4. If you're using Directory Synchronize, verify the Synchronization Summary and Synchronization History in TMEMS for the last synchronization before the issue occurred.

    Sync Summary

    In case there is any discrepancy between the number of recipients, email aliases or groups and the actual number in your organization, verify the Synchronization History in the Directory Synchronization Tool.

  5. If you're using Directory Import, check if the email address is included in the imported CSV or LDIF file.
    You may go to Inbound Protection > Connection Filtering > Recipient Filter to export the list of valid recipients.
