Why Does Outlook Slow Down?

Outlook saves mailbox information in a file called PST (Personal Storage Table). This file continues to develop as you send and receive emails, add attachments and save old ones. When the PST file is too large, Outlook begins showing difficulties such as

Slowly opening and closing
Delays while sending or receiving emails
Frequent freezing or hanging.
Errors with email inquiries
PST files are at risk of corruption.

Microsoft itself recommended that PST files be kept to a safe size. Large PST files are more difficult for Outlook to manage, resulting in slower performance.

Splitting a PST file can help.

Splitting a large PST file into smaller sections can significantly improve Outlook performance. When the size of the PST file is reduced

Outlook loads up faster.
Email searches become easier.
Corruption risks are reduced.
Backup and administration have gotten easy.

Outlook performs better when using multiple smaller PST files than with one large PST file. PST splitting comes in useful in this situation.

Manually splitting a PST file in Outlook

Outlook does not have a direct "Split PST" option, but you can minimize PST size manually by creating a new PST file and putting data into it. This is a basic manual method

Step-by-step Manual Method:

Launch Microsoft Outlook.
Click to File > Account Settings > Account Settings
Open the Data Files tab.
To create a new PST file, click Add.
Name the new PST file and specify its location.
Click “OK.”
Go back to your mailbox folders.
Drag & drop emails, folders, or things from the previous PST file to the new one.
Repeat until the initial PST size is lowered.

The limitations of the manual method are

Large mailboxes might be time consuming
Possibility of human error
No splitting depending on size or date
Not intended for non-technical users
There is no guarantee of full data accuracy

If you have thousands of emails, this process could take hours or even days. That is why so many users prefer a professional service.
