I have configured one queue to one of my mailbox to achieve mail to case functionality. The Email Id I am using in this case is my business Email. I have also set one rule with auto response email template. I configured the inbox with a gmail server with POP enabled. POP is enabled within my Email ID as well, so that the emails are forwarded. But I am facing frequent delays with incoming emails for my CRM. Sometimes I see new incoming emails in the advanced find, sometimes I don't. Any suggestions why this strange behavior?
