Configuring the Default Public Folder Limits
Use the limits settings to control the maximum size of public folders in the public folder store, the maximum size of messages in the public folders, and how deleted items are handled. You can access the limits settings on the Limits tab of the public folder store's Properties dialog box.

The following table describes the options that you can set on the Limits tab for a public folder store.
Warning
Do not set an age limit on folders that contain Contact or Calendar items.
Note
You can also set limits on individual public folders that override the store settings. If you use only the store settings, the same folder may have different limits on different servers. If you use individual folder settings, the limits are the same for all replicas of the folder.
Options available on the Limits tab for a public folder store
| Option | Description |
|---|---|
Issue warning at (KB) |
When a folder exceeds the specified size limit, the administrator receives an e-mail alert to delete messages from the folder. You can type a number from 0 to 2097151. By default, this option is not selected. |
Prevent post at (KB) |
When a folder exceeds the specified size limit, the administrator receives an e-mail alert to delete messages from the folder. Additionally, no users can post messages to the folder until the folder size is reduced below the specified limit. You can type a number from 0 to 2097151. By default, this option is not selected. |
Maximum item size (KB) |
The maximum size for individual messages that can be posted to the folder. You can type a number from 0 to 2097151. |
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 messages in a folder) 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. Because items deleted from public folders are not held in a Deleted Items folder, if you set this option, you can recover deleted items without having to use a backup of the public folder. |
Do not permanently delete items until the store has been backed up |
You can keep deleted items on the server until a backup is performed. After a backup is performed, items are deleted, according to the settings that you specified. You can use this setting for folders that contain important information. For other folders, such as Newsgroup folders, you may want to leave this setting cleared to save storage space. |
Age limit for all folders in this store (days) |
The number of days after which items in this folder will be deleted automatically if they have not been modified. |
