Exchange 2000 Tool: PST2GB v1.5.2
This might still be a handy tool, Exchange 2000 Tool: PST2GB.
Tool for issues discussed in Q296088Specific support tool to create a truncated copy of a .pst file allowing some recovery when the file size has reached over 2 gig. The copy does not have all the original data because the tool cuts a user defined amount of data from the file.
Supported operating systems: Windows 2000, Windows XP
Recovery Limitations of the 2 GB Truncation Utility:
You must have 2 GB of free hard disk space (to make a copy of the .pst file).
The utility truncates the .pst file to under 2 GB. To have enough working space, truncate the file between 20 to 25 megabytes (MB) less than the 2 GB limit. The truncated data is removed from the new copy, which means some messages are missing from the recovered copy.
