I have a wireless network with wpa2 security. All my Samsung devices connect to it with no problems. Connect android to mac bluetooth.

Recently, though, my about 1/2 of my apple devices stopped connecting. It either keeps asking for a password, or just says incorrect password. We have one Google Pixel phone that also doesn't work.

My wifi controllers are Ubiquiti Unifi APs, broadcasting on the 2.4 channel. The iPhones that don't work are of various ios versions, however at least two of them are on version 10.1: One works the other doesn't Here's what I tried so far: • Changed the security to wpa, then to wep, then finally to NO security (just as a test). The problem iPhones still couldn't connect.

When I want to save the changes after selecting 'Allow all.' , I am getting asked for the keychain password, and even there, after typing the correct password, the dialog won't go away and keep asking me for the password over and over.

With no security, they just said 'can't connect to network'. • Turned wifi off the phones, then turned it back on again. • Reset the network on the iPhones.

• Turned off wifi on the location menu (under settings) • Reset all the APs • Tried to manually add the network, entering in which type of security I was using. I still have the problems only with about half the iPhones. What is the usb for on a mac apple monitor.

SSL certs on come AP's and Firewalls / routers in between the phone and the Exchange server I have seen cause challenges like this to check to be sure the SSL certs are passing correctly.

Report back findings Thanks for pointing me to the Outlook App. That seem to resolve the issue. The built in Mail app still errors periodically when connected to the corporate network but the outlook app doesn't.
