How to Prevent Outlook Corruptions from Occurring

Outlook is an incredibly powerful and widely used email client, but it can be prone to data corruption. 

Fortunately, there are 10 steps that you can take to reduce the chances of Outlook corruptions occurring, ensuring your important emails remain safe and secure. 

1. Keep Your Software Up-to-Date

It’s essential to keep all your software up-to-date, especially when it comes to Outlook. Microsoft regularly releases updates that fix known bugs and other issues, as well as introducing new features. Installing these updates on a regular basis will help prevent Outlook corruptions from occurring

2. Backup Your Data Regularly

Regular backups are essential for any computer user, regardless of what type of software they are using. Backing up your data frequently will ensure that you have a recent version of all your emails and other information in the event of corruption or other data loss.

3. Disable Unnecessary Add-Ins

Outlook add-ins can be helpful, but they can also cause problems if they are not working properly. To reduce the chances of an Outlook corruption occurring, it’s best to disable any unnecessary add-ins that you don’t need for your work or personal use. 

4. Scan Your Computer for Viruses & Malware

Viruses and malware can cause severe damage to your computer and its programs, including Outlook. Be sure to regularly scan your computer with an up-to-date anti-virus and anti-malware program to help protect your data from any malicious programs. 

5. Don’t Overload Your Inbox

Outlook is designed to handle a certain amount of emails and other data in each folder. If you overload your inbox, it can cause Outlook corruptions or slow the program down significantly. Make sure that you regularly delete old emails that you no longer need and manage the folders within Outlook efficiently. 

6. Avoid Large Attachments

Large attachments can put strain on Outlook, which could lead to corruptions occurring or other performance issues. Try to break up large files into smaller parts before attaching them, or send them via a cloud storage service or other file transfer method. 

7. Empty Your Deleted Items Folder

Outlook stores deleted emails in its ‘Deleted Items’ folder, which can become quite large over time. Regularly deleting emails from this folder will help keep Outlook running smoothly and reduce the chances of corruptions occurring.

8. Check for Software Conflicts

If you are using multiple software programs on your machine, there is a chance that they could conflict with each other and cause an Outlook corruption to occur. It’s important to regularly check for any conflicts between programs and uninstall any unnecessary software if necessary. 

9. Rebuild the Outlook Index

The index within Outlook helps it find emails quickly, but it can become corrupted over time. Rebuilding the index will help Outlook search more efficiently, as well as helping to reduce the chances of corruptions occurring.
