[The company] does not allow employee-owned communication devices or mobile numbers to become corporate devices. There will be no exceptions made to Corporate Ownership. <unquote> This has been tested several times and the same answer comes back - what part of no don't you understand? iPhones are not on the list of cell phone choices for company phones. Blackberries are but not including the storm. -----Original Message----- From: Kim Longenbaugh [mailto:k...@colonialsavings.com] Sent: Wednesday, July 22, 2009 10:40 AM To: MS-Exchange Admin Issues Subject: RE: OWA / SSL question We said "no", then our owner said "yes".

That strikes me as a bit of a security risk though. -----Original Message----- From: Micheal Espinola Jr [mailto:michealespin...@gmail.com] Sent: 22 July 2009 04:19 To: MS-Exchange Admin Issues Subject: Re: OWA / SSL question Its true and not at the same time. Its true because no, you dont install a self-signed cert. Its false that the iPhone "works" with them, because it doesnt. It ignores the security condition. However, I believe you can put your own certs on an iPhone via the iPhone Configuration Utility. http://www.macworld.com/article/134381/2008/07/iphone_config_utility.html http://www.apple.com/support/iphone/enterprise/ -- ME2 On Tue, Jul 21, 2009 at 7:50 PM, Greg Wright<greg.wri...@wineselectors.com.au> wrote: > This is the best response I have read so far on this subject.
