SYMPTOMS
If you examine the Instances tab in the properties of the public information store and there are over 65,535 public folders, the following error message may be displayed:
An unexpected unknown error has occurred.
MAPI or an unspecified service provider.
ID no: 80040403-0000-00000000
CAUSE
This issue can occur because the Exchange Server Administrator program relies on MAPI to retrieve information about public folders. MAPI architecture only allows 65,535 rows in a table. If more than 65,535 public folders exist, the table is unable to hold all of the entries and the error message in the "Symptoms" section of this article may be displayed.
