# Restoring Messages to a PST File Using Exchange Journaling

Applies to: User Mailbox, and Journal Mailbox

You can restore a mailbox, a message, or a mailbox item to a PST file.

The size of the PST file is limited based on the version of Microsoft Outlook that you use.

Microsoft Outlook Version | Maximum PST File Size
--- | ---
Microsoft Outlook versions older than 2003 | 1.5 GB
Microsoft Outlook 2003 or 2007 | 15 GB
Microsoft Outlook 2010 or 2013 | 30 GB
Microsoft Outlook 2016 or newer | 45 GB

If you try to restore a data set that is larger than the PST size limit, the restore will fail. You can choose to restore large data sets to multiple PST files that are less than or equal to the value that you define. These PST files cannot be larger than 45 GB.

## Before You Begin

- Verify that the destination client has Microsoft Outlook 64-bit 2010 or 2013 installed.

- Review the size considerations for PST files.

## Procedure

1. From the Command Center navigation pane, go to Protect > Exchange.

   The list of all Exchange clients appears.

2. Click the Exchange client that contains the mailbox that you want to restore.

   The Exchange client page appears.

3. Right-click the mailbox that you want to restore, and then click Restore.

   The Backup content page appears.

4. From the Restore to list, select PST file.

5. From the Destination host list, select the name of the appropriate client computer.

6. In the Destination path box, type the path to the location where you want to restore the PST file, including the PST file name with the .pst extension.

   If you want to restore the PST file to a network location, type the UNC path to the location, including the PST file name with the .pst extension.

7. If you want to restore a large data set to multiple PST files, select the Limit PST size to check box, and then enter a size value.

   The size limit cannot be greater than 45 GB.

8. Do either of the following:

   - If you want to create a single PST file that is common to all users, select Create common PST for all users, and then select either a merged folder hierarchy for all users or a preserved folder hierarchy for each user.

   - To create separate PST files for each individual user, select Create a folder per user using, and then select the appropriate folder naming convention from the corresponding list.

9. Click Submit.
