The affected products are:
- Zero Download (My Private Post)
- Trend Micro Encryption for Email (TMEE) [Outlook Client application]
- Trend Micro Email Encryption Gateway (TMEEG)
- InterScan Messaging Security Virtual Appliance (IMSVA)
- Hosted Email Security (HES)
Details on how each product is affected:
The Zero Download service will be unavailable during the maintenance period. Using the browser to decrypt, reply to, and forward encrypted emails will not be possible during this time. A notification will be visible in the browser once the encrypted_message.htm is opened by the user. The Mobile “forward to decrypt” solution is also not available during the maintenance period.
The TMEE Outlook client should still be able to encrypt and decrypt messages if it was used during the October time frame. These messages will have the October and November private key for the registered email addresses. Registering new accounts, however, will fail during the maintenance period. In case an account does not already hold the monthly key, it will fail to encrypt and decrypt emails.
The encryption gateway should continue to decrypt messages for recipients whose October private key have already cached. Messages using the November private key will fail to encrypt or decrypt and will be left on the TMEEG box in the /trend/tmeeg/.errored/ directory.
You may use the Resend TMEEG errored Email.zip
tool to reprocess messages that are stuck in the errored directory. The instructions on how to use the tool is included in download file. The password is "novirus".
Important: The Resend TMEEG Errored Email tool is an unsupported command line utility that helps customers resend emails on TMEEG that have previously failed and are now stuck in the Errored directory. The Resend TMEEG Errored Email tool is provided “AS IS” without warranties of any kind. Trend Micro does not warrant that the Resend TMEEG Errored Email tool is secure or error free, that it will meet your requirements or expectations, that the results will be accurate or reliable, or that errors or issues will be fixed or corrected. You assume all risk arising out of use of this utility. Trend Micro does not provide support for this utility and the Trend Micro Technical Support team is unable to answer questions about the tool.
Only messages with encryption and decryption tasks are affected.
IMSVA should be able to process encrypted messages for whose recipients already have the monthly October key. All other messages will fall into exception handling.
The default action can be configured on the IMSVA user interface section Policy > Scanning Exception > Encryption Exception. Once the maintenance is over, you can check your quarantined emails in the Admin UI (assuming exception handling is set to quarantine) and reprocess these messages.
Messages with encryption and decryption tasks on HES may experience a delay if the monthly key is not yet available. Those that failed during the maintenance window will be automatically re-processed.
