Note
For an individual user, you can override the store's limits settings by using Active Directory Users and Computers to configure limits settings for the user.
The following table describes the possible limits that can be set for a mailbox store. By default, no limits are set.
Options available on the Limits tab for a mailbox store
| Option | Description |

Prevent send at (KB) |

Prevent send and receive at (KB) |
When a user's mailbox exceeds the specified size limit, the user receives an e-mail alert to delete messages from the mailbox. Additionally, the user cannot send e-mail messages until the mailbox size is reduced below the specified limit, and incoming e-mail messages are returned to the sender with a non-delivery report (NDR). |
Warning message interval |
Use this drop-down list to schedule when warning messages are generated. You can select one of the standard maintenance schedules, or click Customize to set up your own schedule. This process is CPU-intensive and disk-intensive, and can slow server performance. It is a good idea to schedule maintenance of this type at off-peak times. |
Keep deleted items for (days) |
You can designate the number of days that deleted items (such as e-mail messages) remain on the server before they are removed permanently. You can type a number from 0 to 24855. If you type 0, deleted items are removed from the server immediately. As long as deleted items remain on the server, Outlook users can retrieve them using Outlook's Recover Deleted Items function. |
Keep deleted mailboxes for (days) |
You can designate the number of days that deleted mailboxes remain on the server before they are removed permanently. After this value is set, you have the specified number of days to recover mailboxes that were deleted by accident. You can type a number from 0 to 24855. If you type 0, deleted mailboxes are removed from the server immediately. |
Do not permanently delete mailboxes and items until the store has been backed up |
You can keep deleted mailboxes and items on the server until a backup is performed. After a backup is performed, mailboxes and items are deleted, according to the settings that you specified. |
