Instant Replay Feature Explained


The Instant Replay feature allows users to send (or resend) an email from Proofpoint Essentials to their messaging server. This may be useful in the following situations:

  • The original email failed to be delivered (bounced/expired)
  • The original email was deleted by the user
Summary Read below to better understand the Instant Replay feature, and how to use it to resend an email via Instant Replay. 


If a user is attempting to send an email that has already been sent, they should be aware that if the email already exists in the destination server's database then many mail systems may not deliver the email again. This will depend on the mail system in use and how it handles duplication.

Microsoft Exchange, for example, has a default duplicate database setting of 7 days. This means if an email comes in with the same messageID and the client submit time is within 7 days of the original, it will delete it as a duplicate. Therefore the user who uses Instant Replay feature to resend an email less than 7 days old will not get the message.

If you are using Microsoft Exchange and wish to enable retrieving messages within 7 days of receipt of the original, please follow the instructions on how to change this setting, available here.

If you are using another email application you should investigate to see if you have the option to adjust this value.

Instant Replay Feature is available only for the customers who have subscribed to the Business, Advanced or Professional Packages.

Please Note:

There are potential issues using this feature with Office 365 that are similar to those noted above with Exchange.
