We provide the ability to retrieve any message accepted and processed by our platform. Rejected message aren't accepted by us, so can't be retrieved. How best to do this, depends on the situation and the number of messages to be recovered. This guide provides information on retrieving messages and restoring mailbox data.

  • Administrators with content view rights responsible for retrieving lost email content.


Accepted Messages


Our storage grid provides an online archiving system that retains all external mail. It also retains internal email if journaling is enabled on your account. Prior to a message moving to the archive, it is temporarily held in the Accepted Messages queue. A message only moves to the archive once it has been delivered or bounced. A message remains in this state for between two and six hours.


View the Accepted Messages page for more information on locating, exporting and forwarding messages.


Archive Messages

After indexing, all messages (including internal) move to the archive and are retained for the retention period configured in your account. From an archive search, you can forward messages to an intended recipient, or export message content in bulk.


Recovering Archive Messages


To recover a message stored in the Archive:

  1. Log on to the Administration Console.
  2. Click on the Administration toolbar button. A drop down menu is displayed.
  3. Click on the Archive | Archive Search menu item  The search screen is displayed.
  4. Fill out the fields as required.
    You can search for messages using various combinations of information. See the Searching the Archive page for further details.
  5. Recovering MessagesWhen the search completes, you're presented with the list of messages that match your specified criteria. From here you can:
    • Select a message or multiple messages using the check boxes, and click on the Forward Selected Items button.
    • Select the top check box to select all messages in the list, and click on the Forward Selected Items menu item.
    • Right click on any message and click on the Message Forward menu item.
    If you don't see the check boxes or the forward button, your account doesn't have content view rights.
  6. Enter the recipient's Email Address.
  7. Optionally click on the Add Attachment or Remove Attachment buttons to add or remove a file.
  8. Click on the Send button. A message is sent containing the original message/s you've selected as individual attachments.


Exporting Bulk Archive Messages 


You can export messages from the archive in bulk. The results of the export can be used to rebuild a user's mailbox, replay inbound only messages to your Microsoft Exchange server, or to simply store the messages on a storage medium of your choice.

The export functionality exports data in 500MB blocks. If your export is larger than this, only the first 500MB is prepared. Once this is downloaded, the next 500MB block is automatically prepared. The maximum number of rows you can export is 50000. If more than 50000 rows are required, you'll need to adjust the search parameters and run multiple exports.

To export messages in bulk:

  1. Search the archive for the desired messages. See the Searching the Archive page for full details.
  2. Select the Messages to be exported using the check boxes to the left of the list.
  3. Click on the Export Data button. 
  4. Select the Columns you want to include.
  5. Select a File Format.
  6. Select a Export Option:
    • Download: Downloads the file to your desktop.
    • Send Mail: Mail the file to your account email.
  7. Click on the Export button. 


You can also bulk export Saved Searches from the archive. See the Saved Archive Searches and Exporting Archived Message Data pages for more information.


Replaying Inbound Messages

You can replay messages to reconstitute mailbox content from Mimecast into a Microsoft Exchange environment (e.g. due to corruption or data loss). Replaying reprocesses and redelivers the selected messages. Therefore you must ensure the messages you are replaying are inbound to your internal users, as any outbound messages selected are redelivered to their intended recipient/s.


See the Replay Inbound Messages page for more information.


Sync & Recover

Sync & Recover allows you to synchronize your user's mailbox folder structure, calendar content, and contacts from Exchange On-Premises or Office 365 (Exchange Online) mailboxes with our archive. You can also create a snapshot of how a user's mailbox appeared at a specific point in time, in order to export or restore the contents.


See the Sync and Recover Getting Started Guide page for full details.

Mailbox Folder Replication

The Mailbox Folder Replication feature continuously extracts folder and message metadata from Microsoft Exchange mailboxes, and submits this to the our platform. Once a user’s mailbox has been successfully replicated, they can view their archived email in a familiar folder view using one of our end user applications.

See the Mailbox Folder Replication page for further information.
