Exchange ActiveSync provides synchronization of mailbox data between Exchange Online and mobile devices. With mobile devices that are enabled for Exchange ActiveSync, users can access their e-mail, calendar, contacts, and tasks anytime and anywhere. To enhance security, authentication from mobile devices to Exchange Online is conducted over an SSL connection using a password and user name.
Exchange ActiveSync technology has been licensed by many device manufacturers. Microsoft Online Services has tested the following leading Exchange ActiveSync devices and found them compatible with Exchange Online and SharePoint Online.
Nokia E series and N series phones: Nokia Mail for Exchange must be installed.
Apple iPhone: iPhone OS v2 or v3 and Safari Mobile browser are required.
Palm Pre phone: webOS v1.1, v1.2, or v1.3 is required.

Other Exchange ActiveSync devices may be also compatible with Exchange Online, but will require testing by the customer or device manufacturer. Other Exchange ActiveSync-enabled devices may also include browsers which can access SharePoint Online sites, but customer or device manufacturer testing will be required for these as well.
