Product: Exchange
Event ID: 1080
Source: MSExchange Unified Messaging
Version: 08.01.0106.000
Symbolic Name: QuotaExceededFailedSubmit
Message: The Unified Messaging (UM) server failed to process messages for user “%1” during the call with ID “%2” because the user has exceeded their mailbox quota.
   
Explanation

This Warning event indicates that the computer that has the Unified Messaging server role installed was not able to accept any new voice or fax messages intended for the user specified in the event description. If this occurs, the Unified Messaging (UM) server delivers a response to the user who tried to send the voice message, and then disconnects the call. For example, the UM server response may be: “Sorry, the user’s mailbox is full. Please call back later.” This event may occur if the Exchange mailbox for the user specified in the event description exceeds the configured storage limit. Storage limits for a user’s mailbox can be configured at the user level or at the Exchange database level.

   
User Action

To resolve this warning, do one or more of the following:

  • Increase or remove the storage limit defined at the Exchange database level or at the mailbox level. For more information configuring storage limits, see How to Configure Database Limits and Properties and How to Configure Storage Quotas for a Mailbox.

  • Archive or delete messages from the user’s mailbox to reduce the size of the mailbox to less than the storage limit. To obtain mailbox information such as the size of the mailbox, the number of messages it contains, and the last time it was accessed, use the Get-MailboxStatistics command. For more information, see Get-Mailbox Statistics.

Note  If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
