This topic provides information about how to troubleshoot a problem in which you use public folders in your Exchange Server 2007 organization, and you also have set the retention period on the public folder database to be greater than 123 days. After you install Update Rollup 2 for Exchange Server 2007 Service Pack 2 (SP2), and then you try to access the public folder database by using the Exchange Management Console, you receive the following error message:

If you try to access Exchange by using Outlook Web Access, you receive the following error message:

This problem occurs because of an existing issue in Exchange Server 2007. In this case, the value of the database item retention limit for the public folder in Active Directory is configured in seconds instead of in days. The Exchange Store expects this value in days. Therefore messages may never expire.

This problem is fixed in Update Rollup 2 for Exchange Server 2007 SP2 by using days instead of seconds. However, if a public folder database retention limit is set to greater than 123 days in Exchange Server 2007, and if you apply Update Rollup 2 for Exchange Server 2007, you receive an exception error. This error occurs when you try to access the public folder store by using either the Exchange Management Console or Outlook Web Access.

If you are using public folders, and if you have set the retention period on the public folder database to be less than or equal to 123 days, you receive a warning message. However, Exchange Server 2007 continues to function correctly.

Regardless of the value setting, if you receive this error message or warning message, you can use the following steps in the "Procedure" section to fix the problem.
