Hello All, We have an application that requires POP. We have enabled POP on our BE server and since it is only required internally, we specify which IP's can connect. What we are seeing is that the application checks the mailbox every minute to see if anything has arrive - after a couple of hours, the user account gets locked out. Has anyone seen this? Is there a setting I need to change somewhere? I assume that since the app has logged in properly for the first 2 hours that it shouldn't be a password issue... Thanks in advance!!!

Hi As you know, exchange account is integrated with AD. Exchange wont lock mailbox account. expect this. Exchange Test CAS Connectivity user gets locked out when using Exchange 2010 MP According to your saying, you had better check your group policy of your AD. You can find lock event and find clue of it. TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com Terence Yu TechNet Community Support
