If you need to export the data from Outlook 2003 and import that data into a previous version, you will receive the following error message:
The file file_name.pst is not compatible with this version of the Personal Folders information service.
Contact your Administrator.
Since you are the administrator, you need to resolve this problem. The actual problem is occurring because Microsoft is using the Unicode format to export information from Outlook 2003 into a .PST file. Earlier version of Outlook can not open this file format; they can only read .PST files that are formatted in American National Standards Initiative (ANSI).
To avoid this problem, follow the steps below:
1. Start Outlook 2003
2. From the File menu, select the Data File Management option and click Add
3. Select the Outlook 97-2002 Personal Folders File (PST)
4. Click OK
5. Click OK to accept the default name and then click OK again. This step will create a compatible .PST file in Outlook 2003.
6. Click Close.
7. Open the Folder List to view the new .PST file.
8. Drag the contents from the existing Outlook 2003 .PST file into the compatible .PST file.
Ensure you note where the compatible .PST file is stored. When Outlook XP has been re-installed you will need to import this file to retrieve your Outlook data. The key to this procedure is to have a working copy of Outlook 2003, without Outlook 2003 you will be out of luck.
