This topic describes how to enable or disable Internet Message Access Protocol 4rev1 (IMAP4) access for a user on the computer that is running Microsoft Exchange Server 2007 that has the Client Access server role installed and the IMAP4 service enabled. In the original release (RTM) version of Exchange 2007, you could only enable or disable IMAP4 access by using the Exchange Management Shell. In Exchange 2007 Service Pack 1 (SP1), you can also enable or disable IMAP4 access by using the Exchange Management Console. Steps for doing this are included in this topic.

Note:
After you have enabled or disabled IMAP4 access for a user, you must restart the IMAP4 service. For more information about how to restart the IMAP4 service, see How to Start and Stop the IMAP4 Service.

Before You Begin

To perform the following procedure on a computer that has the IMAP4 service enabled, the account you use must be delegated the Exchange Server Administrators role and membership in the local Administrators group for the target server. 

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.
