Continue reading the article to know more about PST file corruption. 

Don’t Bloat Your PST File 

Even though the MS Outlook 2003 and 2007 versions support PST file size of 20GB, the Outlook 2010 version comes with 50GB of PST file size. However, make sure the size of your PST file should not cross more than 15GB. This is because:

  • Most operations with massive PST files are extremely slow and time-consuming. 
  • Large files often face corruption. 
  • Even though the MS Outlook SCANPST tool can fix some minor corruptions, if the size of the PST file is large, then the process will become highly time-consuming. 

Outlook version 2003, 2007, and 2010 now allows users to open multiple PST files together in the left panel. Therefore, you should move the PST files from your emails into numerous diverse PST files with the Outlook rules. This way you can reduce the size of each PST file. 

Make Sure the Old PST File Version Doesn’t Exceed 2GB 

Microsoft Outlook 2002 and the previous versions restricted the size of the PST file to 2GB. Every time the size of the PST file is close to 2GB, you will face numerous problems. Not to mention, the PST files will become extremely vulnerable to corruption. This is why you need to ensure that the size of the PST file for the old MS Outlook version is less than 1.8GB. This is a good practice you need to remember. 

Don’t Operate With Large Volume of Emails 

MS Outlook will start malfunctioning if you start operating a massive number of emails at one time. This problem is known as deadlock. And after the dead-lock, you will have no choice but to shut down your MS Outlook application forcefully which might cause PST file corruption. You might also lose the PST data files permanently. The experimental limit of MS Outlook is 10,000 emails. Therefore, if you want to choose, copy, or move more than 10,000 emails, make sure you don’t try to complete the batch within one batch. Instead, consider operating 1,000 emails at once. Repeat the operations until your needs are fulfilled. 

Don’t Save the PST Files on Server or Network Drive 

PST files are designed in such a way that they should be stored properly on a computer hard drive. Make sure you don’t store the PST files on your server or local drive. This is because the network environment is not designed to support the dense access of the PST file. This is one of the most common causes of corruption. Additionally, don’t share the PST file on the network. Additionally, you should also prevent multiple users from accessing the same copy of the PST file via the network simultaneously. This will make the PST file prone to corruption. As per Promax, cloud storage comes with additional costs

Don’t Close Outlook Application Forcefully When It’s Still Running 

If you force close the MS Outlook software when the application is completing tasks or processes, then the PST files associated with the MS Outlook will be damaged and corrupted. Sometimes, the damages are so severe that the PST files will be corrupted permanently. Therefore, make sure you never use task manager to shut down your MS Outlook application abruptly. 

Sometimes, Outlook will run in the background even if you close it. Therefore, make sure you check the background running application so that you don’t end up with a corrupted PST file. 

Make Sure You Close Outlook Properly Before Powering Down Your Computer 

This is another important point you need to remember so that you can prevent PST Outlook corruption. Make sure you close the MS Outlook application properly before you shut down your computer. Failing to do so will corrupt the PST data files and you might fail to recover them. Even if the process takes time, make sure the Outlook application is closed properly and not running in the background. You can also deploy some effective apps that will do this process on your behalf.
