Introduction: If you see the following email error message: “Mailbox size limit exceeded,” it means that your mailbox is overflowing and you need to make some room in your inbox. In this post, we’ll go over the problem of the Outlook mailbox size limit exceeded. So please stay in contact with us.

Microsoft Outlook is a powerful email application that comes with a slew of capabilities. If you’ve been using this email client software, it is possible that you have faced Mailbox file size restrictions. It is one of the most common errors in Outlook and occurs when the PST file size exceeds the maximum size allowed.

The maximum size of a PST file varies per version. In Outlook 2002, the file size limit is just 2 GB, however in Outlook 2016, the max PST file size is 50 GB. As a result, the newer versions allow for more data storage. However, once the limit is reached, you will receive an Outlook mailbox size limit exceeded error.

Reasons for an Excessively Large Outlook Mailbox

There are a variety of factors contributing to this problem. Most common are as follows:

Exchange Server is up and running, and the mailbox size restriction has been established.
Duplicate Items in Outlook Mailbox when using an earlier version of Outlook
Having a large number of attachments in your Outlook email is a nuisance.

The explanations listed above are the mostly seen. If you are experiencing the same problem, you may seek assistance from the options we will discuss further down this article.

How one can resolve Outlook Mailbox Size Limit Exceeded error?

Solution 1: Delete the duplicate items from your Outlook mailboxes

We already know that duplicate objects take up the same amount of space as the original items do.

After that, click the view mailbox size option to scan the mailbox size, as well as any subfolders, in order to find any problems.
Now choose the option to identify a larger or older email that you may remove immediately from the cleanup process by selecting it from the list.
