The Instant Replay feature allows users to send (or resend) an email from Sentinel Messaging 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
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 client submit time 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 or Professional packages.
Please Note: This feature cannot be used with customers using Office 365 as a mailbox. This is due to how Office 365 handles duplicate message detection.
