SYMPTOMS

Messaging Application Programming Interface (MAPI), Post Office Protocol version 3 (POP3), Internet Message Access Protocol, Version 4rev1 (IMAP4), and Hypertext Transfer Protocol (HTTP) e-mail clients may experience very slow response from the Exchange Server information store, and gradually the information store may stop responding to the clients.

When a Microsoft Outlook user tries to log on, the user receives the following error message:
The Microsoft Exchange Server computer is not available. Either there are network issues or the Microsoft Exchange server is down for maintenance.
The Microsoft Windows Task Manager displays high CPU use for the Exchange Server information store and a large number of threads in the Store.exe process. The number of threads in the Store.exe process continues to increase, which causes the Store.exe process to stop responding.

CAUSE

This issue can occur if the information store process becomes stuck indefinitely in a loop when a folder cannot be deleted.
