The size of an Exchange mailbox keeps growing with the inflow of messages/ message attachments, and the addition of contacts, notes, calendar entries, and so on. Gradually, the size of the mailbox reaches a saturation point where it becomes difficult for users to manage extensive data. It not only affects the performance of Exchange but also increases the chances of data corruption. Fortunately, Exchange administrators can put a limit on the size of the mailbox sizes by setting a quota in various parameters.
The Storage Limits for an Exchange mailbox specifies a limit where the user will get a warning and a limit where the message flow stops.
Input a value for the database size and Exchange will provide a warning when it reaches the size.
The Exchange will prohibit the user from sending a message when it reaches the limit you specify here.
The Exchange will prohibit the mailbox from both sending or receiving messages when it reaches the value you entered here.
The Exchange will keep the deleted items for the number of days you mention here.
The Exchange will keep the deleted mailboxes for the number of days you mention here.
There are different ways in which end users can manage the size of their mailboxes. Here, we will discuss them too.
Move Messages to PST Files
If you do not want to delete your information stored in the mailbox but want to reduce the mailbox size, then you can move data from the mailbox to a PST file. You can select the lesser important messages and keep them in a PST file. The benefit of this is that it keeps the files saved at a local drive rather than on the Exchange Server. So, it reduces the mailbox size without deleting the data. Here is the simple procedure to create a Personal Folder in Outlook;
Enable Auto-archive in Outlook

Using these techniques, you can effectively reduce the size of the Exchange mailbox and improve its performance.
Apart from setting the size limits and reducing the mailbox sizes, there are many things Exchange administrators can do to ensure the best performance of Exchange Server. However, for this, you need minute details regarding the functioning of the entire Exchange environment. That’s why you should go for a reporting software which records all activities of Exchange and brings the information in a format which you understand easily. Kernel Exchange Reporter is a simple tool that can help you in this regard.
