1.Specify the format of the source files in "Source File Format" combo box, according to the version of the Exchange client. If you are using Exchange client 5.0, 5.5 or Outlook 97-2002, then please select "Outlook 97-2002" as the format. If you are using Outlook 2003-2010, the please select "Outlook 2003-2010" as the format. If you are using Outlook 2013-2019/Office 365, the please select "Outlook 2013-2019/Office 365" as the format. Note if you specify "Outlook 97-2002", "Outlook 2003-2010", or "Outlook 2013-2019/Office 365" format, then all source OST data to be recovered in batch must be in the same format, for example, Outlook 2013-2019/Office 365 format. If the actual format of one source OST data is different from the format specified in "Source File Format", then that file will not be recovered. If you don't know the format of the source OST data, or if the source OST data are in different formats, then you can select "Auto Determined" so that DEXR will determine the format of the source OST data automatically.
2.Specify the format of the fixed target PST files in "Target File Format" combo box. All the recovered PST files will be output in that format. If you have Outlook 2003-2019/Office 365 installed, then you can specify the output format as either Outlook 97-2002 format, or Outlook 2003-2019/Office 365 format. However, if you have Outlook 97-2002 installed, then you can only specify Outlook 97-2002 format. You may also select "Auto Determined" option so that DEXR will output fixed PST files according to the version of Outlook installed on your computer, i.e., the fixed files are in Outlook 97-2000 format if Outlook 97-2002 is installed, or in Outlook 2003-2019/Office 365 format if Outlook 2003-2019/Office 365 is installed.
3.Click "Add Files" to add OST files to the "List of files to be recovered" list. The initial recovery status is "Not Recovered".
4.Click "Search Files" to search and select Microsoft Exchange offline storage(.ost) files to be recovered on the local computer.
5.Click "Remove Files" can remove the selected files in the list.
6.Click "Remove All" can clear the list.
7.If your OST file is stored on the following file:
•VMWare VMDK(Virtual Machine Disk) file(*.vmdk). For example, you store your OST file on a virtual disk in VMWare.
•Virtual PC VHD(Virtual Hard Disk) file(*.vhd). For example, you store your OST file on a virtual disk in Virtual PC. Or you make a backup of your OST file via Windows Backup and Restore function.
•Acronis True Image file(*.tib)
•Norton Ghost file(*.gho, *.v2i)
•Windows NTBackup file(*.bkf)
•ISO image file(*.iso)
•Disk image file(*.img)
•CD/DVD image file(*.bin)
•Alcohol 120% Mirror Disk File(MDF) file(*.mdf)
•Nero image file(*.nrg)
and you cannot access the data in the OST file for some reasons, for example:
•You delete your OST file from the virtual disk in VMWare or Virtual PC.
•You format the virtual disk in VMWare or Virtual PC by mistake.
•The virtual disk in VMWare or Virtual PC cannot be mounted or launched properly.
•The virtual disk in VMWare or Virtual PC is corrupt or damaged.
•The backup file on the backup media is corrupt or damaged and you cannot restore your OST file from it.
•The disk image file is corrupt or damaged and you cannot retrieve your OST file from it.
