NOTE: If the error code 0x2740 is not present in the event ID 11506 or event ID 11508 message, then this article does not describe the issue you are experiencing.



CAUSE
This issue can occur if another program is using the Transmission Control Protocol (TCP) port that the information store uses for the corresponding protocol. If a program is already using port 110, 119 or 143, the information store is unable to open these ports for the Post Office Protocol, version 3 (POP3), Network News Transport Protocol (NNTP) or Internet Message Access Protocol, version 4rev1 (IMAP4) protocols respectively.



RESOLUTION
To resolve this issue, quit the program or service that is using the ports that the information store uses, or configure the program to use different ports.



MORE INFORMATION
You can use the Netstat.exe utility to display the ports that are in use on the Exchange Server computer. To do so:  Open a command prompt, and then run the following command:

netstat -an

 In the Local Address column, look for an Internet protocol (IP) address and port combination that ends with the port in question.

For example, if you receive an error message that indicates that the information store is unable to register the POP3 port (110), stop the Information Store service, run netstat -an, and then look in the Local Address column for a line ending in &quot;:110&quot;. This line indicates that port 110 is currently in use.
