In Exchange Server, user mailboxes save emails and all other user data. When we talk about the mailbox, you should know that there are multiple types of mailboxes in Exchange–
- User mailbox – User mailboxes are primary mailboxes which store emails, contacts, notes, journals, etc. of the user.
- Room mailbox – Room mailbox is a resource mailbox which is assigned meeting rooms. The access to room mailboxes can be assigned to various users.
- Equipment mailbox – Equipment mailbox is another resource mailbox which is associated with portable devices like laptops.
- Linked mailbox – A linked mailbox is a mailbox associated with an account in a different AD forest.
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.
