Error while dumping the Exchange Mail Boxes. Unable to create the PST file [or] "No new/modified files for backup"

1. This error occurs when Giga Vault Storage is installed as service in 'Local System Account' or logon user without "Full Mailbox" rights on Exchange Server.

   If you have installed Giga Vault Storage as service in 'Local System Account', change the Giga Vault Storage service's logon account to the user account who has the "Full Mailbox" rights on Exchange Server. You can change the Giga Vault Storage service's logon account type by following the steps:

   1. Open the Services control applet through "Control Panel -> Administrative Tools -> Services" shortcut or by running "services.msc" command in "Start -> Run" tool.

   2. Select the Giga Vault Storage service and then open its Properties dialog.

   3. In the Giga Vault Storage services Properties dialog, go to the "Logon" tab and update the user logon to be of the power user or a user who has full Administrative privileges to run the Giga Vault Storage service.

   4. After providing the correct user name and password details, click 'Apply' and 'Ok' to apply the changes.

   5. Restart the Giga Vault Storage service.

2. This error might show up when 'MSPST MS' is not configured in the Exchange Server.

   Add the 'MSPST MS' service by modifying the MAPISVC.INF file.

   The MAPISVC.INF file should have the information of the Microsoft Personal Folder store service. If this file does not have this information, then the Exchange MailBox dump will fail with an error indicating that it is unable to create the PST file.

   The MAPISVC.INF file is usually located in the Windows system directory (e.g.C:\Winnt\System32). If you have installed Outlook on the Exchange Server machine it may also exist in the common system program files area (e.g. C:\Program Files\Common Files\System\Mapi\1033). If you have multiple versions of this file then you should make sure that they are the same.

   Verify the file has an entry for the Microsoft Personal Folder store service. You can determine this by looking for the following information. If this information is not in the file then you need to add it in the proper sections:

   [Services]
   MSPST MS=Personal Folders File (.pst)

   [MSPST MS]
   Providers=MSPST MSP
   PR_SERVICE_DLL_NAME=mspst.dll
   PR_SERVICE_INSTALL_ID={6485D262-C2AC-11D1-AD3E-10A0C911C9C0}
