Why User Need to Split PST Files?

  1. File Size Limit: Outlook has a maximum file size for PST files. Earlier versions of Outlook limited the maximum file size to 2 GB. For later versions, the maximum number of PST files in Unicode format is 20 GB. If your PST file exceeds this limit, you may experience performance issues, corrupt the file, or be unable to open it. Splitting the file allows you to control the size of the file and avoid such problems.
  2. Performance Optimization: Large PST files can slow down Outlook’s performance, causing delays when opening and searching emails and overall slowness. You can improve Outlook’s performance by splitting the PST file into smaller, more manageable pieces.
  3. Accessibility and Portability: Splitting PST files improves accessibility and portability. Small Outlook data files can be simply transferred, copied, or shared between different devices or email clients without the need for Outlook.
  4. Avoid Corruption: Large PST files are more prone to corruption and data loss. Splitting it into smaller files reduces the risk of losing all your emails and data if the file gets corrupted. Corruption of individual PST files does not affect other files.

these cases, the problem will exist until you delete some of your data. But deleting your data is not the ultimate solution to this problem. Another approach you can adopt is to compress the size of the PST file to make it smaller.
