How to Enable or Disable Outlook Mobile Access at the User Level
By default, Outlook Mobile Access is disabled when you install Microsoft® Exchange Server 2003. For users to use Outlook Mobile Access, you must first enable it. You enable Outlook Mobile Access for specific users or groups of users with Active Directory Users and Computers.
Before You Begin
You can perform this task using Active Directory Users and Computers, with or without the Exchange Task Wizard. The advantage to doing it with the Exchange Task Wizard is that you can modify the settings for multiple objects at one time.
To enable or disable Outlook Mobile Access at the user level
Log on to the Exchange server as an Exchange administrator with the user's mailbox, and then start Active Directory Users and Computers.
Expand the domain, and then open the location for the users whose settings that you want to modify.
Right-click the user or users whose Outlook Mobile Access settings you want to modify, and then select Exchange Tasks.
In the Exchange Task Wizard, on the Available Tasks page, select Configure Exchange Features, and then click Next.
On the Configure Exchange Features page, select Outlook Mobile Access, and then select one of the following:
To allow users to use Outlook Mobile Access, select Enable.
To prevent users from using Outlook Mobile Access, select Disable.
To prevent the users' settings from being modified when you have selected more than one user, select Do not Modify.
Click Next to apply your changes.
