ParticipantA PST to EML conversion can be quick and easy when everything goes smoothly. Unfortunately, a lot of users report that things slow down enormously. There are several factors that can affect your speed.
Why does PST to EML Conversion Slow Down?
- Overly large PST file – If you’re converting a huge PST file (5-10 GB and larger), it’s going to take longer because it is just a larger file.
- PST file with corruption – If the PST you’re converting is corrupted, the PST to EML converter may not be able to read it.
- Insufficient available resources – If there is very little RAM, CPU, or drive space available for the conversion process, this will obviously slow down your processing speed even further.
- Manual tools/solutions – Most manual tools or solutions (especially the free ones) are not optimized for the conversion process and are rarely provided a define speed.
- Keep Outlook closed, and all other non-essential programs waiting in the background while you convert PST to EML in the same environment (Windows and Outlook)- be as kind to your computer as you can for maximum speed and efficient conversions.
How to Resolve Slow Conversion Speed
These are some practical approaches to try:
- Split large PST files
Use Outlook’s native functions or a PST splitter to reduce a huge PST into smaller files prior to conversion. - Repair the PST file
Run Microsoft’s Inbox Repair Tool (ScanPST.exe) to remove corruption before converting. - Quit any unnecessary applications
Make sure any other potentially resource-draining software, in addition to Outlook, is closed so that there is enough free RAM and CPU to complete the conversion. - Ensure you have available disk space
Check that your system has enough free hard drive space to handle the temporary files generated during conversion. - Don’t manually drag-and-drop for large files
Manual methods will work for a small quantity of emails but take too long for bulk PST response.
