Keep the PST file size within limits

Since we have already mentioned that PST files have specific size limitations, it is best to not cross the size limitation. We know that most outlook operations are slowed down by large PST files and they are the most prone to corruption. So if we want to avoid Outlook mailbox Corruption, we should keep the PST files within limits. Microsoft Outlook 2002 and earlier PST files need to be kept below 2 GB. Outlook 2003-2007 PST files need to be kept below 20 GB. Outlook 2010-2013-2016 and later version files need to be kept in sizes below 50 GB.

Do not save PST files on network drive or server-based systems

We know that PST files can be of large sizes and that is one of the reasons we should not depend on network or server drives. Storing your PST files in a network server may cause Outlook mailbox corruption and the slowing of your Outlook app due to connection speed. Additionally, when we use network based servers and many users work on the same files at the same time, there are chances of Outlook mailbox corruption. So it is considered to be the safest bet to store your PST files in your physical hard drive.

Backup PST files regularly

The best way to not lose something is to keep a solid backup. This keeps your data safe at all times, even if it gets corrupted in the application. That is why we always recommend you to get back up your PST files at a regular interval. This helps you keep your peace of mind and gives you the confidence to work freely without the fear of Outlook PST mailbox corruption.

Close Outlook properly/Turn off computer properly

One of the most common reasons why people get their PST files corrupted is abrupt or improper closing of the Outlook application. Many times you are working on a large PST file when the power goes out or you close the Outlook improperly. This results in the corruption of the whole PST file that you were working with. So it is best to ensure that you have a power backup to avoid sudden crashes. You should always wait for the application to fully close before shutting down the system.

Work on a limited number of mails at once

The experiential limit of MS Outlook is 10,000 mails. However, it is recommended to work on only 1000 or less emails at a single time to avoid the possibility of corruption. If you select, copy, move or delete a very large number of email files, there are chances of your Outlook doing into a lockdown. So to avoid this form of Outlook mailbox corruption, keep your one time file use limited.
