A user mailbox in an Exchange Server database is the container to save the emails of a single Exchange user. The name of the mailbox follows the name of the Exchange account and all the emails, contacts, notes, sent items, calendar etc. are present in the mailbox.
When you are going to create more than 20 mailboxes, then you should make sure that any mailbox has not grown more than the others, taking maximum space in the database.
There are some checksums that you can apply to the properties of the mailbox so that the user gets to know about the increasing size of the mailbox.
All these parameters can be set from Exchange admin center (EAC).
You should also know that it is not only the user mailbox that is present in Exchange, but some other mailboxes also.
Gradually, when the data increases, it becomes quite messy to manage a large mailbox. When the size of a mailbox increases, you can think of increasing the size limit of mailboxes. And if users face any send/receive issues due to the size of emails, you can raise the size limit of emails too.
There is no size limitation for any mailbox in Exchange 2010 (though there is a default value for it). But Exchange Administrators always like to maintain a size limit for user mailboxes. It helps them utilize the disk space efficiently. But sometimes, you need to adjust the size of Exchange 2010 mailbox, so that the user can easily handle the mailbox data.
Here is a brief process to modify the size limit of the mailbox –
Make changes in the limits and finally click OK.
Sometimes, users face problems when they want to send/receive large emails or attachments. This is because the user cannot also send/receive emails when the emails are bigger. But administrators can change the email size limitation from the Exchange Management Console. Let’s see it also:
So, these were two simple methods which you can use to modify the size limits of an Exchange Server mailbox or emails.
When the size of Exchange grows beyond a limit, it may prove fatal for the whole environment. An Exchange Administrator must know the status of each mailbox always, and there is no manual way to get the status of any mailbox. But you can use any monitoring tool which can analyze the Exchange Server and provide complete details related to mailboxes, mailbox folders, and traffic.

In Exchange 2010, you can use Exchange Management Console to increase the size limit of mailboxes as well as emails. But it is important to know the current size of user mailboxes in advance. This is possible with Kernel Exchange Reporter.
