I'm a substitute teacher, and during most of the school year the district does not issue me network access nor do I have an email account, but for the occasional long term sub position I am given these things on a temporary basis. I have one such long term coming up and I went ahead and set up my Exchange account for the district on my iPhone in order to get that email there. As soon as I enabled the account it switched my passcode lock time from 4 hours to 15 minutes. Going into passcode settings I can see that the max lock time is now 15 minutes instead of 4 hours. The only reason I had it on a 4 hour lock time before was so that I only had to type it in once or twice a day instead of typing in my AppleID password every time I want to use that feature (my wife and I use it a lot to save on the busywork communication when we're coming and going places). Now, I totally get why this happens: it's extra security, and if I'm adding an organizations Exchange email to my phone they should get a say in how the security is handled, but here's where logic fails: I stilll have the ability to turn the pass code off altogether! Does that make any sense to anyone else? I can't set a passcode time for longer than 15 minutes, but I can just turn the stupid thing off if I want. Why on earth is "pass code is optional, but if it's on it can only be set at a maximum 15 minute interval" even an option? Makes no sense.
