Outlook is a popular email client used by many individuals and professionals to communicate with other people. However, there are times when Outlook corruptions occur which can lead to data loss and inaccessibility of emails. Therefore, it is important to take a proactive approach against Outlook corruptions. This article will discuss ways that users can reduce their risk of encountering Outlook corruptions and provide tips on how to mitigate the effects of Outlook corruption if it does occur. 

Tips for Reducing Risk: 

1. Regularly backup your PST files: 

PST stands for ‘Personal Storage Table’ and these files contain all of the emails, contacts, tasks, calendar entries, etc., from your Outlook account. Backing up these files on a regular basis is an effective way of reducing the chances of data loss due to Outlook corruption. 

2. Minimize the file size:

Large PST files are more prone to corruption, so it is important to minimize its size from time-to-time by using the ‘Archive’ feature. This feature allows users to move old emails and other items into separate folders which can then be backed up or deleted when no longer needed. 

3. Use trusted anti-virus software:

It is essential that all online activities are protected with trusted anti-virus software as malicious viruses and malware can cause severe damage to Outlook and lead to corruptions. Make sure that these programs are updated regularly in order to protect against the latest threats. 

4. Install Windows updates:

Windows updates can help protect your system from potential vulnerabilities that could be exploited by malicious actors to corrupt Outlook files and data. Therefore, it is important that all necessary patches are installed promptly when they become available. 

5. Avoid using third-party add-ons:

Third-party add-ons have been known to cause compatibility issues with Outlook which can result in impairments or even complete failure of certain features and operations. As such, it is best to avoid their use where possible as they could potentially increase your risk of corruption. 

6. Check for storage space availability: 

Outlook corruptions can occur if there is insufficient storage space on the computer or mobile device. Therefore, it is important to check that there is sufficient free space available before attempting any activities in Outlook. 

7. Monitor the size of PST files:

Users should monitor the size of their Outlook PST files and delete any unnecessary emails or other items if they become too large. This will help reduce the chances of encountering corruption due to insufficient storage space. 

8. Use caution when sending attachments:

Attachments can increase the risk of Outlook corruptions if they contain malicious code or viruses, so users should be careful when sending them out by email. It is also wise to scan all incoming attachments for potential threats before opening them in order to protect against infection and data loss. 

9. Do not share PST files with others: 

Sharing PST files with other users can increase the chances of corruption as any changes made by one user could potentially compromise the data of another. Therefore, it is recommended that each user has their own Outlook account to ensure maximum security and reliability. 

10. Repair Outlook application if necessary:

If Outlook is not functioning properly or exhibiting strange behavior, then this may indicate that there is a problem with the application itself. In such cases, it is best to repair the installation in order to restore normal operation and reduce your risk of encountering corruptions due to software malfunctions. 

11. Don’t open suspicious emails: 

Malicious emails containing viruses or malware can cause severe damage to an Outlook installation if opened, so it is important to practice caution when dealing with unsolicited emails in order to protect your data. If you are ever unsure about the authenticity of an email, then delete it without opening rather than taking any chances. 

12. Use online backup services:

Saving a copy of your Outlook PST files to an external hard drive or cloud storage service can provide an extra layer of protection against data loss due to corruptions. Many providers offer automated backup solutions which can make regular backups hassle-free and help ensure that your data remains safe. 


Overall, following these simple tips can help reduce the risk of encountering issues with Outlook due to corruption and ensure that all of your emails, contacts, tasks, calendar entries and other items remain safe. 

It is important to keep in mind that data loss due to Outlook corruptions cannot always be avoided, but with the right precautions in place, you can minimize the chances of it happening to you.
