Many transaction log files are generated in a short time on an Exchange Server 2003 server

Many transaction log files are generated in a short time on a Microsoft Exchange Server 2003 server. Additionally, you may experience the following symptoms:

• An unexpected increase in the size of the database.
• A heavy load on server resources.
• The Microsoft Exchange Information Store Service may temporarily stop responding. This behavior causes a disruption of the messaging services.

This problem occurs if a user performs one of the following actions by using Microsoft Outlook Web Access (OWA):

• Attaches a file to an e-mail message that exceeds the maximum limit that is configured for the user's mailbox or for the Microsoft Exchange organization.
• Posts an item to a public folder that exceeds the maximum limit that is configured for the public folder.

After you install the hotfix that is described in this article, an OWA user receives an error message when the user tries to attach or to post an item that is exceeds the maximum limit.

However, the large item is transferred to the server because security restrictions do not allow for verification of the attachment on the client. But, the large item is not committed to the database if the maximum limit is exceeded.
