From: Ed Crowley [MVP] on 8 Jun 2010 12:42 If you enable both 110 and 995, the client will choose the port it uses. If you want only secure access, then you must block unsecured POP, which means port 110 won't be answered. ActiveSync doesn't use POP or IMAP, it's a separate service that runs over HTTPS. How his BlackBerry connects depends on his serivce provider. An iPhone works very well with ActiveSync--it's arguably the best ActiveSync client out there right now. If you had Exchange 2007 you'd be amazed how well Autodiscover works with iPhones. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." ..

Generally speaking, yes. >If its >listening on both ports then doesnt it mean that its going to give out >pop mail securly or insecurly. (not sure if thats english) If you listen on port 110 and an e-mail client connects on that port then SSL won't be used -- even if you had a SSL certificate installed. If that's not acceptable you should remove the entry for port 110. >> Does the phone have ActiveSync on it? >I have no Idea, its the CEO's phone. Its a blackberry. Blackberry doesn't have ActiveSync. But he'd be better off using IMAPS instead of POPS. You only have access to your Inbox with POP. >But He says hes >dumping it and going to get a IPHONE. The iPhone has ActiveSync. --- Rich Matheisen MCSE+I, Exchange MVP

But Im not sure how I would check. You should be able to click on the "Certificate" button on the POP Virtual Server's property page. --- Rich Matheisen MCSE+I, Exchange MVP
