How To Fix “Outlook Data File Reached The Maximum Size Error?

As far as we know Outlook is a widely used email client by individuals and businesses worldwide. However, users often encounter a message stating “The Outlook data file reached the maximum size,” indicating that the mailbox has exceeded the maximum storage limit. In this article, we’ll discuss the causes, solutions, and prevention methods of the Outlook data file exceeding the maximum size.

What Causes the Outlook Data File to Reach the Maximum Size?

Large Attachments

Attachments such as videos, images, and other files can take up considerable storage space in your mailbox. When you send or receive attachments regularly, it can contribute to the data file exceeding the maximum size.

Email Messages

Over time, accumulated emails in your inbox, sent items, and other folders can fill up your mailbox, resulting in the Outlook data file exceeding the maximum size.

PST and OST File Size Limits

Microsoft Outlook has a default file size limit of 20 GB for PST (Personal Storage Table) files and 50 GB for OST (Offline Storage Table) files. When the PST or OST file exceeds the set limit, it can lead to the Outlook data file reaching the maximum size.

Solutions to Resolve the Outlook Data File Reached the Maximum Size Error

Archive Old Emails and Attachments

Archiving old emails and attachments can reduce the storage space occupied by your mailbox. You can set up automatic archiving to move older emails and attachments to a separate PST file. This reduces the size of the primary data file, ensuring that it stays below the maximum limit.

Compact the Data File

Outlook has a built-in compact feature that removes the empty space within the data file created by deleting or moving items. This can significantly reduce the size of the data file, allowing it to stay within the maximum size limit.

Split Large PST Files

If your PST file has already reached the maximum size, splitting it into smaller files can resolve the issue. You can use third-party software such as Shoviv for PST Split to split large PST files into multiple smaller ones without losing any data.

Disable or Reduce the Size of Attachments

You can prevent your mailbox from exceeding the maximum size by reducing or disabling the size of attachments in Outlook. To do this, go to File > Options > Mail > Attachment Options and adjust the attachment size limit to your preference.

Prevention Methods to Avoid the Outlook Data File Reached the Maximum Size Error

Regularly Delete Unwanted Emails and Attachments

It’s essential to regularly delete unwanted emails and attachments to prevent your mailbox from filling up. You can use the auto-archiving feature to keep your mailbox organized and reduce the size of the primary data file.

Sending and receiving large attachments can quickly fill up your mailbox, causing it to exceed the maximum size limit. It’s best to use cloud storage services like OneDrive, Dropbox, or Google Drive to share large files.

Use the Online Archive Feature

Microsoft offers an Online Archive feature that allows users to move old emails and attachments to a separate online location. This helps to keep the primary data file size small, preventing it from exceeding the maximum size limit.

Conclusion

In conclusion, the Outlook data file exceeded the maximum size error can be frustrating, but it’s preventable and solvable.
