Restore Deleted emails from an Outlook OST File

Efficient email management plays a vital role in day-to-day business operations, and platforms such as Outlook and Exchange Server offer quick access to emails and other data. However, accidental deletion of mailboxes or important email items can result in sudden data loss, which may interrupt communication and impact overall productivity.

In general, when emails or folders are deleted in Outlook, they are moved to the ‘Deleted Items’ folder, from where they can be restored easily. However, when these items are permanently deleted either manually or due to mailbox retention policies, recovering them is more complex. In such cases, EdbMails OST to PST Converter proves to be a reliable solution, as it enables you to recover deleted emails from OST files with efficiency and accuracy.

Recover deleted mailboxes from OST guide

EdbMails enables recovery even when the original Outlook profile or Exchange server connection is unavailable. Through a step-by-step interface, the tool guides you in restoring lost mailbox data, making the process both accessible and reliable for users of all technical levels.

Reasons for OST File data deletion

There could be many reasons for OST file data deletion, but in practice, it can be categorized into two different types.

  • Soft Deletion: In this situation, the email data is not permanently deleted from the system. It is moved to the Deleted Items folder in Outlook and then you can restore the data to retrieve these deleted items.
  • Hard Deletion: In this situation, the OST file data is deleted permanently. And you cannot recover the data from the Deleted Items folder.

Reasons for permanent deletion of OST file data

  1. When the Shift+Delete key is pressed for deleting an item, it leads to permanent deletion.
  2. When the Deleted items folder is accidentally emptied without backing up the data.

You can use ScanOST for Outlook to retrieve and export the deleted emails from the Deleted Items folder. But if the OST file cannot be opened or if the mail items are permanently deleted from this folder, the only option is to restore your emails from a backup OST snapshot.

Practical situations of deleted email recovery from Outlook files

Here are some real time scenarios where recovering deleted email items from an OST file can be necessary:

  • Accidental Deletion: An email can be accidentally deleted by a user, which may result in the permanent loss of important data. In such cases, EdbMails can help to recover deleted mailboxes or items from an OST file and export them to a PST file.
  • Corruption: OST files may get corrupted due to unexpected system shutdowns, malware infections, or hardware issues, making some emails inaccessible or causing them to be deleted. EdbMails helps in such situations by repairing the damaged OST file and recover deleted emails or items, ensuring you can retrieve important mailbox data without relying on Outlook or the original server.
  • Malware Attacks: Malware attacks can cause significant damage to OST files, resulting in data loss. EdbMails can recover deleted emails or items from an infected OST file, ensuring that important data is not lost.
  • Accidental Modification: Users may accidentally modify or overwrite important email items, which can result in data loss. EdbMails can help to recover deleted mailboxes or items from an earlier backup of the OST file.
  • Exchange Server Crash: An unexpected Exchange Server crash can make mailbox data inaccessible or lead to the deletion of important emails. EdbMails enables you to recover those deleted items directly from the OST file, without any connection to the original server. You can also export recovered Outlook emails to an external hard drive for safe, long-term storage and easy access.

    Step 2: Select the OST file for the recovery

    • Click ‘Browse for OST file'.

      Browse for OST file

    • Select the offline OST file from your local drive, then click the ‘Next’ button to continue. You can also share the OST file on a network with read and write permissions assigned.

      Select OST file

    • Click ‘Browse’.

      Click Browse

    • Select the destination folder to save the exported PST files, and ensure the drive has enough free space to complete the export.

      Select PST location

    • EdbMails scans the offline OST file and recovers mailbox data, even when the file is damaged or corrupted. During the process, the tool analyzes the file structure and contents to extract emails and other mailbox items. The time required depends on the file size and the level of corruption, so wait until the scan completes to ensure full recovery.

      Recovery operation progress

    • After the recovery process finishes, the application displays all OST file data while preserving the original folder and subfolder hierarchy. You can expand any mailbox folder to easily explore its contents. When you select a specific folder, such as Emails, Contacts, Notes, Tasks, or Calendar, all associated items are listed and shown with a clear, detailed preview panel. Additionally, EdbMails OST to PST Converter allows you to open OST files without requiring Outlook to be installed on your system.

    Step 3: Preview and select the deleted mailbox

    • Check the ‘Show All the folders’ option and expand the mailbox.
    • Locate the ‘Recoverable Items’ folder, expand it, and then open the ‘Deletions’ subfolder to view deleted items.

      Deleted OST items

    Step 4: Export the mail items from Outlook OST to PST to recover deleted emails or items.

    • EdbMails OST to PST converter ensures fast and accurate conversion of offline OST files to PST format. Review the selected mailboxes and folders for the export operation, ensure the ‘Action’ is set to ‘Export’, and then click the ‘Start Export’ button to begin the export process.

      Start OST to PST Export

    • The export process has started, and you can track its progress through the status bar. The interface shows the mailbox and folder being exported, the destination PST file location, and the count of items successfully exported. When the export is complete, EdbMails will display a message confirming that the operation has finished.

Frequently Asked Questions (FAQ)

  1. Can I restore deleted emails from an OST file if the Outlook account no longer exists?

    Yes. EdbMails can recover deleted emails directly from an OST file even if the original Outlook profile, Exchange mailbox, or Office 365 account has been deleted or is no longer accessible. The recovery does not depend on reconnecting to the original account.

  2. Does restoring deleted emails from an OST file require an Exchange Server connection?

    No. EdbMails works completely offline and does not require access to Exchange Server or Exchange Online. This makes it suitable for recovery scenarios where the server is unavailable or the mailbox has been removed.

  3. Can I preview deleted emails before restoring them from the OST file?

    Yes. EdbMails provides a built-in preview option that allows users to view deleted emails, folders, and other mailbox items before exporting them. This helps ensure only the required data is restored.

  4. Is it possible to restore only specific deleted emails instead of the entire mailbox?

    Yes. EdbMails supports selective recovery, allowing users to choose specific deleted emails or folders from the OST file rather than restoring the entire mailbox. This saves time and storage space.
