Exchange ActiveSync

In Exchange 2010 SP1, you can manage Exchange ActiveSync devices using the Exchange Control Panel (ECP). Administrators can perform the following tasks:

• Manage the default access level for all mobile phones and devices.
• Set up e-mail alerts when a mobile phone or device is quarantined.
• Personalize the message that users receive when their mobile phone or device is either recognized or quarantined.
• Provide a list of quarantined mobile phones or devices.
• Create and manage Exchange ActiveSync device access rules.
• Allow or block a specific mobile phone or device for a specific user.

For every user, the administrator can perform the following tasks from the user’s property pages:

• List the mobile phones or devices for a specific user.
• Initiate remote wipes on mobile phones or devices.
• Remove old mobile phone or device partnerships.
• Create a rule for all users of a specific mobile phone or device or mobile phone type.
• Allow or block a specific mobile phone or device for the specific user.

SMS Sync

SMS Sync is a new feature in Exchange ActiveSync that works with Windows Mobile 6.1 with the Outlook Mobile Update and with Windows Mobile 6.5. SMS Sync is the ability to synchronize messages between a mobile phone or device and an Exchange 2010 Inbox. When synchronizing a Windows Mobile phone with an Exchange 2010 mailbox, users can choose to synchronize their text messages in addition to their Inbox, Calendar, Contacts, Tasks, and Notes. When synchronizing text messages, users will be able to send and receive text messages from their Inbox. This feature is dependent on the user’s mobile phones or devices supporting this feature

Reset Virtual Directory

In Exchange 2010 SP1, you can use the new Reset Client Access Virtual Directory wizard to reset one or more Client Access server virtual directories. The new wizard makes it easier to reset a Client Access server virtual directory. One reason that you might want to reset a Client Access server virtual directory is to resolve an issue related to a damaged file on a virtual directory. In addition to resetting virtual directories, the wizard creates a log file that includes the settings for each virtual directory that you choose to reset. For more information, see Reset Client Access Virtual Directories.
