You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Recipient Provisioning Permissions" section in the Mailbox Permissions topic.

1. In the console tree, navigate to Recipient Configuration > Mailbox.
   


2. In the result pane, select the mailbox user for whom you want to configure storage quotas.
   


3. In the action pane, under the mailbox user's name, click Properties.
   


4. In <Mailbox User Name> Properties, click the Mailbox Settings tab.
   


5. Click Storage Quotas, and then click Properties.
   


6. In Storage Quotas, clear the Use mailbox database defaults check box, and then complete the following fields:
   
   
   
   
   • Issue warning at (KB)   Use this check box and use the corresponding text box to specify the maximum storage limit in kilobytes (KB) before a warning is issued to the mailbox user. The value range is from 0 through 2,147,483,647 KB. If the mailbox size reaches or exceeds the value specified, Exchange sends a warning message to the mailbox user.
     
   
   
   • Prohibit send at (KB)   Use this check box and use the corresponding text box to specify a prohibit send limit in KB for the mailbox. The value range is from 0 through 2,147,483,647 KB. If the mailbox size reaches or exceeds the specified limit, Exchange prevents the mailbox user from sending new messages and displays a descriptive error message.
     
   
   
   • Prohibit send and receive at (KB)   Use this check box and use the corresponding text box to specify a prohibit send and receive limit in KB for the mailbox. The value range is from 0 through 2,147,483,647 KB. If the mailbox size reaches or exceeds the specified limit, Exchange prevents the mailbox user from sending new messages and won't deliver any new messages to the mailbox. Any messages sent to the mailbox are returned to the sender with a descriptive error message.
     


7. Click OK to return to the Mailbox Settings tab.
   


8. Click OK.

This example sets the warning, prohibit send, and prohibit send and receive limits for John Smith's mailbox to 200 megabytes (MB), 250 MB, and 280 MB respectively.

Note:
To make sure that the custom settings for the mailbox are used rather than the mailbox database defaults, you must set the UseDatabaseQuotaDefaults parameter to $false.

Set-Mailbox -Identity [email protected] -IssueWarningQuota 209715200 -ProhibitSendQuota 262144000 -ProhibitSendReceiveQuota 293601280 -UseDatabaseQuotaDefaults $false

If you change the size limit of your Exchange databases, you may want to evaluate your Exchange database backup and restore plan. Specifically, if you increase the size limit of the Exchange databases, test your backup and recovery operations using the new database size limits to make sure that you can still meet your service level agreements (SLAs).

Caution:
Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.

1. Start Registry Editor (regedit).
   


2. Locate the following registry subkey:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<Server Name>\Private-<database GUID>
   
   
   
   
   
   
   
   
   

   Note:
   You can get the GUID of a database by running the following command in the Exchange Management Shell: Get-MailboxDatabase -Identity "<database name>" | Format-Table Name, GUID



3. If the Database Size Limit in GB DWORD exists for the subkey, change its value to the desired size in gigabytes.
   


4. If the Database Size Limit in GB DWORD doesn't exist for the subkey, create a new DWORD with that name, and then set its value to the desired size in gigabytes.
