Split Pst File - Can't Start Outlook with Oversized PST
For example, consider a situation when you try to start Microsoft Outlook 2002 or an earlier version. The application may fail to start with no notice or some errors, such as it cannot open the default mail folders.
Cause
The above symtoms can occur if you are using an oversized .pst file as your default mail delivery location.
Such problems are not encountered in Outlook 2003 or Outlook 2007 since these versions support Unicode format. Therefore, the default file size limitation of .pst file is 20 GB, which is much larger than its earlier limit.
Solution
You can these methods to overcome the described file oversize issue:
1-You can upgrade your ANSI formatted file to new Unicode format in Outlook 2003 or higher version.
2-If this fails, you can use pst2gb tool. But this is not a preferred method as you lose some data permanently while file truncation.
3-You can Split PST to obtain several smaller .pst files. In this operation, each file contains a part of original PST, but is less than 2 GB in size value. Split PST File software can safely divide a large .pst file, where each file is directly usable with Outlook.
