SYMPTOMS

When you are using the Microsoft Exchange Connector for POP3 Mailboxes to download e-mail messages from individual or global Post Office Protocol version 3 (POP3) mailboxes, the POP3 Connector may not download the messages. The following errors may be logged in the Application log:
Event ID 12050
Source: POP3Connector
"POP3: Failed to check the POP3 account for mailbox at host POP3Server.contoso.com on port 110. The error is 10060"

Event ID 12058
Source: POP3Connector
"POP3: There was an error processing the RETR command. The Error is 10060"
The following event messages may be logged instead of those listed earlier in this article:
Event ID 12050
Source: POP3Connector
"POP3: Failed to check the POP3 account for mailbox at host POP3Server.contoso.com on port 110. The error is 1232"

Event ID 12058
Source: POP3Connector
"POP3: There was an error processing the RETR command. The Error is 1232"

-or-

Event ID 12050
Source: POP3Connector
"POP3: Failed to check the POP3 account for mailbox at host POP3Server.contoso.com on port 110. The error is 10054"

Event ID 12058
Source: POP3Connector
"POP3: There was an error processing the RETR command. The Error is 10054"
Substitute the name of your mail server for "POP3Server.contoso.com" in these error messages.

CAUSE

This problem may occur if specific packets are fragmented during the communication between the POP3 Connector and the POP3 server. The symptoms may seem to be intermittent; later attempts to download the messages may work.
