When a user is attempting to download mail from Microsoft Exchange Server by means of POP3 or IMAP with Secure Sockets Layer (SSL) enabled, the user may get the following error message even though the server certificates have been installed properly:
You may also see the following events logged in the Exchange Server event log:
Description: Accept clients on POP3 interface failed in function HrRegisterProtocol with error 0x2741.
Description: Accept client on external interface POP3 failed with error 0x80004005.
Source: MSExchange IMAP4
Description: Accept clients on IMAP4 interface failed in function HrRegisterProtocol with error 0x2741.
Description: Accept client on external interface IMAP4 failed with error 0x80004005.
This problem can be caused if the Network Associates GroupShield for Microsoft Exchange virus program is running on the server containing the POP3 mailbox.
Completely uninstall GroupShield and attempt to connect to Exchange Server using the POP3 client with SSL enabled. After you verify that this is successful, you should be able to re-install GroupShield and have no further problems.
Disabling SSL enables the client to download mail if GroupShield cannot be immediately uninstalled and reinstalled.
