Exporting PST Files Using ExMerge on Exchange 2003

ExMerge is a Microsoft utility used to extract data from mailboxes on a Microsoft Exchange Server. The program copies data from a source server into .PST files. These files are used to move data from your current in-house Exchange environment into your Rackspace Exchange accounts. Note: ExMerge does not export public folders and will only work with mailboxes.

Step 2 – How to use ExMerge

ExMerge has a 2GB limit on the size of a mailbox that may be exported. The 2GB limit is after the export is complete, so the size of the file prior to the export must not exceed roughly 1.85GB.

  1. Open Exmerge.exe on your local server.

     

  2. Select Extract or Import (Two-Step Procedure).

     

     

  3. Select Step 1: Extract data from an Exchange Server Mailbox.

     

  4. Enter the name of the Exchange server you are exporting from and leave the Optional Information boxes blank.

     

  5. If you have several Available Databases, choose the location of the mailbox to be exported.

     

  6. Select the mailbox or mailboxes to be exported.

     

  7. On the Locale Selection page, click Next.
  8. Select a directory where the files will be exported.

     

     

Step 3 - Confirm File Creation

Once the wizard has completed the export, it will automatically close. Locate and review the .PST file in the specified folder.

Tips for a Successful Export

For files larger than 2GB, use the Options button on the Source Server page and click on the Dates tab. You can then specify a date range for the .PST being exported to help reduce size.

Issues that may occur when exporting data with ExMerge are:

  • Incorrect permissions. You may be able fix this by creating a new service account.
  • Information store is dismounted.
  • User account associated with the mailbox is disabled.
  • Not enough disk space in the location where the .PST files are being stored.
  • Mailbox is over 2GB in size.
  • Corrupt items in mailbox. If this happens, your only option is to export using Outlook. ExMerge will not export corrupt items.
