Individual mailbox size in Exchange 2007

How large can a individual (single) mailbox size be in Exchange 2007. My First Storage (Public) is  limited to 200 GB. I am looking to increase the size of this mail box from 1 GB to 2 GB. And the current actual size of First Storage group is 20GB.

From this article on TechNet:

Understand that there are no inherent size limits on individual mailboxes. The main factors that limit mailbox size are as follows: available disk space, backup and restore times, service level agreements, and Outlook performance. When we refer to Outlook performance, we are specifically referring to the latencies experienced by the end-user.

Essentially, there is no real limit, but the number of items in a mailbox can affect load times / performance within Outlook.
