This topic describes how to use the Exchange Management Console and the Exchange Management Shell to set the calendaring options that are available on the Microsoft Exchange Server 2007 computer that has the Internet Message Access Protocol Version 4rev1 (IMAP4) service enabled. In the original release (RTM) version of Exchange 2007, you could only manage calendar options for IMAP4 by using the Exchange Management Shell. In Exchange 2007 Service Pack 1 (SP1), you can also manage calendar options for IMAP4 by using the Exchange Management Console. Steps for doing this are included in this topic.

You can set different calendar options for your organization when you are using IMAP4 as the e-mail protocol for your users. In the original release (RTM) version of Exchange 2007, you can use the CalendarItemRetrievalOption parameter for the Set-IMAPSettings cmdlet in the Exchange Management Shell to set different calendar options.

The following table describes the CalendarItemRetrievalOption parameter for IMAP4 users.
