Exchange Email on Android 5.1 I recently upgraded my Nexus 5 to Android 5.1. Now my corporate exchange email no longer updates.  I can not send or receive emails. I had my local IT department check it out and they can not find anything wrong.  All of the settings are exactly the same as they were prior to the update.  Any suggestions?
A fellow Nexus 5 owner in my office who had not yet upgraded his to 5.1 showed me his settings.  The security type on his was SSL/TLS, while mine was set to SSL/TLS (Accept all certificates).  I changed mine to SSL/TLS and it works now.  I'm not sure why this worked but I can get my emails now.
