After you install Exchange Server 2003 (or Exchange 2000 Server Service Pack 1 or later), when you post a new item with an attachment that is larger than 1 megabyte (MB) to a public folder, you receive the following error message:

This item exceeds the maximum size defined for this folder and cannot be saved. Contact your administrator to have the folder limits increased.

Follow this procedure to resolve this issue.

  2. Expand Public Folders and then right-click the OWAScratchPad folder. Click Properties, and then click Limits.

  3. Under Storage Limits, the Maximum item size (KB) is set to 1,024, or 1 MB, by default. To change the limit:

    • Under Storage Limits, change the limit in the Maximum item size (KB) box.

    • Click Use public store defaults. When this check box is selected, the limit settings are controlled by the Maximum items size (KB) setting and the Prohibit post at (KB) setting on the Limits tab of the public folder store Properties dialog box. However, if the store is configured by a system policy, the settings are located on the Limits tab of the policy's Properties dialog box.
