Situation: company A with 5 users. user 1 is the manager and god knows why, he prefers using pop emails on his iOS device. domain is abc.com and mx record is set to an external mail provider who is filtering against spam and viruses using a server with pop accounts. pop3 connector downloads emails from this external provider mail server to the company A internal exchange 2010 (sbs2011). so far this is very easy to do and this works just fine.
The issue is that if any exchange user from company A sends an email to user 1, the emails remains in exchange and goes straight into user 1 exchange mailbox. Since the user 1 sets up his iOS on the external POP3 mailbox on the external mail provider, he doesn't receive his exchange colleages emails until he gets back to the office and check his Outlook client which is setup on his exchange mailbox.
Any suggestion ? I tried setting his iOS using pop to connect directly to the exchange server (by enabling pop service...ports and all of that) but somehow I was not succesfull. I'd prefer to find a solution for the above scenario.
