Set Limits on Public Folder Stores in Exchange 2000

You use a slightly different procedure to set limits on public folder stores than the procedure that you use to set limits on a mailbox store because you cannot set the prohibit send setting on a public folder.

1.	Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
2.	In the left pane, expand the Exchange 2000 hierarchy until you find the Servers container. If an Administrative Groups container is displayed, the Servers container is under the respective administrative group.
3.	Expand the Servers container, click the server that hosts the public folder store that you want to configure, and then double-click Storage group in the right pane.
4.	Right-click the public folder store that you want to configure, click Properties, and then click the Limits tab.
5.	Click to select one or all of the following check boxes under Storage limits: a. Issue warning at: Select this check box to warn the users that have public folder Owner or Folder Contact roles that their public folder has exceeded its limit. However, normal functioning of the public folder continues. b. Prohibit post at: Select this check box to prevent new messages from being posted to the folder if the folder reaches the size that you specify. c. Maximum item size: Select this check box to prevent anyone from posting messages that are larger than a certain size, regardless of how full the folder is. NOTE: Type the size value in KB for the majority of the public folders that are hosted in this store, for example, type 20,000 KB for the limit of a message-based public folder and type 100 KB for the Maximum item size setting.
6.	Either click the time that you want the warning messages to be generated in the Warning message interval box or click Customize.
7.	If you click Customize, either click a day in the left column and a time on the top row or click and hold the mouse button as you sweep across the time slots to configure warning settings. NOTE: To configure the schedule to be displayed in hour slots or in 15-minute slots, click the appropriate setting under Detail View.
8.	After you configure the warning message interval times, click OK.
9.	If you want maximum control of your database sizes, configure the Keep deleted items for (days) setting to 0. Otherwise, Microsoft recommends that you a configure this setting to 7 days. Deleted item retention time is more important on public folders, where items are deleted immediately and are not sent to the Deleted Items folder.
10.	After you finish configuring public folder store limits, click OK.
