Cause of "PST is not compatible" error!

This problem normally occurs when the user import PST information through the import or export wizard. The Outlook 2003 and Outlook 2007 supports Unicode format to export information to a .pst file. Earlier version of outlook supports ANSI format to import or export the information. When the user imports earlier version of PST information in Outlook 2003 or 2007 version the outlook raises “Pst is not compatible” error message.

How to fix "PST is not compatible" error message?

If you have some important information in PST file that supports ANSI format then there is some easiest way through which you can import the PST file successfully in the newer version of outlook.

To import the earlier version of PST file in newer version of Outlook, just create a new PST file in Outlook 2003 or 2007 in ANSI format. Then move the information on newly created PST file. To create a new PST file, go through the following steps:

• Open Outlook
• Go to the File > Data File Management, and then click to Add.
• Now click Outlook 97-2002 Personal Folders File (PST)
• Then thrice click OK to accept the default file name.

You have successfully created PST file in ANSI Format. Now you can use the import and export wizard to move the information from old PST file to new PST file.
