POP3 email client disconnects randomly in an Exchange Server 2013 environment

Applies to: Exchange Server 2013 EnterpriseExchange Server 2013 Standard Edition


When you use the Microsoft Exchange Post Office Protocol 3 (POP3) service to log on your email client in a Microsoft Exchange Server 2013 environment, the connection stops and then reestablishes frequently. During the disconnection time, new emails can't be downloaded.


This issue occurs because the proxy session times out during lock contention.



Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
