The Migration Wizard does not migrate all the calendar items in Exchange Server 2003 Service Pack 1 (886948)


The information in this article applies to:

  • Microsoft Exchange Server 2003 Enterprise Edition, Service Pack 1 (SP-1)
  • Microsoft Exchange Server 2003 Standard Edition, Service Pack 1 (SP1)

SYMPTOMS

After your mailboxes are migrated from Microsoft Exchange 5.5 to Microsoft Exchange 2003 Service Pack 1 by using the Exchange Migration Wizard, you may notice that not all the calendar items in Exchange Server Service Pack 1 are migrated. Instead, only some of your calendar items are migrated.

CAUSE

A change was made in Microsoft Exchange 2003 Service Pack 1 to avoid duplicating calendar items during migration from an Exchange 5.5 calendar to an Exchange 2003 calendar.

When you paste a calendar item from an Exchange 5.5 calendar to an Exchange 2003 calendar, the new calendar item shares the unique identifier with the old calendar item. Therefore, the two calendar items are considered duplicate items. Only the calendar item that was modified last is migrated.
