We have just upgraded our Exchange 2010 to Service Pack 3. This is on SBS 2011, if it makes a difference. Mobile users (iOS and android both) were immediately required to set PINs on their phones. This is a problem for us. In Exchange Management Console, we went to Org Config > Client Access > Exchange ActiveSync Mailbox Policies. Right-clicked Default (it's the only policy there) and went to properties. Went to Password tab, and unchecked the "Require Password" box. iPhone users are no longer required to set a PIN, but Android users are. We have tried removing the mailbox from the Android phones entirely and then setting them up again, but it still requires passcode. On an Android phone that has never been configured for email access we tried this, and it also required passcode.
Is there any way that we can make it so that Android users do not have to set a passcode? My google searches have been unsuccessful. We'll be very appreciative of any help that can be offered.
If you remove the password checkmark before they setup their mailbox it might have been the policy had not been updated yet.
