• Activesync or Blackberry Enterprise are the preferred methods, as they will synch your mailbox Calendar and Contact items as well as mail items. IMAP/POP only supports synchronization of mail items.
• Most iOS, Android, and Windows Phones support Activeysnc, as do the newest Blackberry 10 devices. older Blackberry devices leverage the Blackberry Enterprise protocol to connect.
• Connecting via Activeysnc or Blackberry Enterprise protocols requires that you accept the ANL Security policy on your phone the first time you connect.
• The only rule that enforced by the ANL mobile device security policy is a screen lock with a 4 character password. Accepting this security policy will not limit your mobile device in any other way.
