Email polling against Exchange 2013 failing

zpbonjour

Hello everybody! I'm working on setting up a new installation of osTicket to use as our companies internal trouble ticketing and KB solution. I was able to get everything working flawlessly except for polling a mailbox for new emails. Here's my setup:Exchange 2013Windows Server 2012 R2 - IIS8.5 (osTicket host)PHP 5.5LDAP pluginAll servers are on the same network with no firewalls/port filteringphp_imap.dll is enabledOn my Exchange CAS servers, both POP and IMAP are enabled and configured to use TLS/SSL with a valid cert from digicert.com. The POP and IMAP services are running on both CAS and both database servers.I am able to login to OWA with the account that I need monitored, but when I enter it's information on the 'update Email' form, I receive the error "Too many login failures". I receive the same error message on both POP and IMAP even when SSL is not used.Warning: imap_open(): Couldn't open streamIs there any further information that I should provide?

What version of osTicket are you running?Please consult your php error log and see if there is anything being logged there.Please consult your Exchange event logs and see if you can find the login attempts, or anything about the connection attempt.Have you searched the forums and read the other Exchange threads?

Figured it out!We are in the middle of migrating Exchange 2007 to Exchange 2013. Our helpdesk mailbox was was on the old database servers for another reason. After migrating it to the new 2013 database servers IMAP worked great. OSticket and PHP did not like the database redirection that the 2013 CAS servers were doing.
