Microsoft Outlook is one of the most popular email clients in the world. It is used by millions of individuals and businesses to send and receive emails, manage contacts, and schedule appointments. While Outlook is an incredibly useful tool, it is not without its problems. One of the most common issues faced by Outlook users is the overly large PST (Personal Storage Table) file.
An Overly Large PST file can cause various problems such as slow performance, PST corruption, difficulty in backup and restore, and even Outlook crashes. In this article, we will discuss the reasons why an Overly Large PST file is a problem and explore some effective ways to reduce the size of your PST file without losing any important data. By following these tips, you can avoid these issues and improve the performance and reliability of your Outlook.
What Makes an Overlarge PST File a Concern for Outlook Users?
The Overlarge PST (Personal Storage Table) file is a common problem for Microsoft Outlook users. PST files are used to store emails, attachments, and other Outlook data. As users continue to receive and send emails, the PST file grows in size, and when it reaches a certain point, it can cause various problems.
Here are Some Reasons Why an Overlarge PST File can be a Problem:
- Slower Outlook Performance: An Overlarge PST file can slow down the performance of Outlook. When Outlook has to open and close the PST file, it takes longer to perform these operations. This can make it difficult to search for emails or attachments, resulting in a slower user experience.
- Risk of PST Corruption: The risk of PST file corruption increases as the file size increases. PST files can become corrupted due to various reasons such as power failure, system crashes, or other technical issues. When this happens, it can lead to data loss, and in some cases, it can be challenging to recover the lost data.
- Difficulty in Backup and Restore: An Overlarge PST file can also make it challenging to backup and restore Outlook data. When the PST file size exceeds a certain limit, it can cause issues with the backup process. It can also take longer to restore a large PST file, which can be frustrating for users who need to access their data quickly.
- Outlook Crashes: An Overlarge PST file can cause Outlook to crash or freeze. When this happens, users may need to force-close Outlook and restart it. This can lead to data loss and can be frustrating for users who need to access their emails or attachments urgently.
To avoid these issues, it’s essential to manage your Outlook data carefully and keep the PST file size under control. By regularly archiving old emails, compressing large attachments, and using online storage services, you can reduce the size of your PST file and avoid these problems.

7 Different Ways to Reduce Outlook Mailbox Size Without Deleting Emails
Are you struggling with a bloated Outlook mailbox? Do you find it difficult to search for important emails or attachments? If yes, then you need to take some measures to reduce the size of your Outlook mailbox. A cluttered mailbox not only affects the performance of your email client but also makes it difficult to manage your emails efficiently.
Approach 1: Archive Old Emails to Reduce the Size of Outlook Mailbox
One of the most effective ways to reduce Outlook mailbox size is to archive old emails. Archiving moves your older emails to a separate file that is stored on your computer or a network location. Archiving will not delete your emails but will move them to a different location, making them easily accessible when you need them.
To get started, open MS Outlook and follow the steps below:
Step 1. Go to the File tab and click on Info.
Step 2. Select the Tools option and click on Clean Up Old Items.
Step 3. A pop-up box titled “Archive” will appear. Choose the “Archive this folder and all subfolders” option and select the file or folder that you want to archive.
Step 4. Check the option “include items with ‘Do not Auto Archive’ checked” to archive files that you do not want to include in automatic archiving.
Step 5. Click OK to complete the process.
By following these simple steps, you can easily archive your old Outlook mails and reduce the size of your PST file without deleting any important data.
Approach 2: Compress Large Attachments to Reduce Outlook Mailbox Size without Deleting
Another effective approach to reducing the size of your Outlook mailbox is to compress large attachments.
Attachments, such as high-resolution images, PDFs, and other large files, can take up significant amounts of storage space in your mailbox. By compressing these attachments, you can reduce their file size without compromising their quality.
To compress attachments in Outlook, you can follow these steps:
Step 1. Open the email with the large attachment(s).
Step 2. Click on the attachment to select it.
Step 3. Click on the File tab and select the Compress Pictures option.
Step 4. Choose the compression options you prefer, such as the picture quality or resolution.
Step 5. Click on the OK button to apply the changes.
Step 6. Repeat the process for any additional large attachments.
Alternatively, you can use third-party compression software to compress files before attaching them to your email. This can help you reduce the size of the attachment even further.
The SysTools PST Compress Tool is a professional solution for handling extremely large PST files that cannot be managed through manual methods.

Approach 4: Use Online Storage to Reduce Outlook Mailbox Size
One effective approach to reducing the size of your Outlook mailbox is to utilize online storage.
With the help of online storage services such as Google Drive, Dropbox, or Microsoft OneDrive, you can easily store attachments and other files outside of your Outlook mailbox. This can help prevent your mailbox from becoming too large and slowing down your email program.
To use online storage for this purpose, you can follow these steps:
Step 1. Save the attachment or file to your computer.
Step 2. Upload the file to your preferred online storage service.
Step 3. Create a link to the file and include it in your email instead of attaching the actual file.
This approach has several advantages. It not only reduces the size of your mailbox but also allows you to share larger files than what is possible through email attachments alone. Additionally, using online storage can provide an extra layer of security and protection for your files, since they are backed up in the cloud.
However, it’s important to note that using online storage should not replace backing up your Outlook mailbox regularly. Always make sure to back up your mailbox to a local or external hard drive to prevent the loss of important data in case of any unexpected issues with your online storage service.
Approach 5: Delete Duplicate Emails to Reduce Outlook Mailbox Size
One effective approach to reducing the size of your Outlook mailbox is to identify and delete duplicate emails.
Duplicate emails can accumulate in your mailbox over time, especially if you receive a large volume of emails on a regular basis. These duplicates can take up valuable storage space and slow down your email program.
To identify and delete duplicate emails, you can follow these steps:
Step 1. Open your Outlook mailbox.
Step 2. Click on the Home tab and select the Clean Up option.
Step 3. Choose the Find Duplicate option.

Step 6. Click on the Find button to start the search.
Step 7. Review the list of duplicate emails found by the search.
Step 8. Select the duplicates you want to delete.
Step 9. Click on the Delete button to remove them from your mailbox.
It’s important to note that before deleting any duplicates, you should review them carefully to ensure that you’re not deleting any important emails. Also, it’s a good idea to backup your Outlook mailbox before making any major changes, just in case something goes wrong.
