Exchange Server is Microsoft’s enterprise email, calendaring, contact, scheduling, and collaboration platform. It is an enterprise-class server that is primarily focused on sending, receiving, and storing email messages for all of the users in the organization. The current version is Exchange Server 2019.

There’s no doubt that Exchange is a mission-critical infrastructure component and its continuous availability is essential to all businesses that run it; Exchange supports clustering for server-level high availability. However, server-level clustering can’t protect you if the Exchange data store becomes corrupted. While it is typically very reliable, the Exchange data store can become corrupted for a variety of reasons that can result in the loss of important data across the entire organization and even the disruption of all email services until the data stores are repaired.

Microsoft Exchange Server stores its critical data in an Exchange database file (EDB file). Each Exchange Server creates one EDB file that contains all the mailboxes, emails, calendars, contacts, attachments, and tasks for all of the users in the organization. If the EDB file is damaged or corrupted being able to rapidly repair it is critical for the organization’s business continuity. In this product review, you’ll see how Stellar Repair for Exchange can repair EDB file corruption. First, we’ll look into some of the common reasons that might cause EDB file corruption. Then you’ll see how to install Stellar Repair for Exchange and use it to repair a corrupted EDB file.

The mapping process is required to make sure that the mailbox data from the EDB file is exported to the desired mailbox on the destination server.

Stellar Repair for Exchange provides the option to either Auto-Map or Manually Map the mailboxes. Using Auto-mapping, Stellar Repair for Exchange automatically searches for the mailbox of the user on the destination server with the same name and email address as the user’s mailbox in the source EDB file. If Stellar Repair for Exchange doesn’t find a matching destination mailbox on the target server, then you have to manually create a new user mailbox and export the data to that new mailbox. Manual mapping allows you to either change the destination of the mailbox that is mapped or select a destination mailbox for a mailbox that has not been automatically mapped.

  • Priority – This column gives a higher importance to mailboxes that need to be exported first.

The Status column lists the current status of the export process. The Total Items Processed shows the number of items exported to the destination mailbox. Percentage shows the progress of the saving process. The Stellar Repair for Exchange can process up to four mailboxes at a time during the export process. This parallel processing reduces the time required to repair and save mailboxes. The Remove button on the far right of the screen allows you to remove specific mailboxes from the list of mailboxes that are being processed.
