The following are known issues that occur when you use the Microsoft Transporter Suite for Internet Mail to migrate mailboxes:

• After you migrate iCal items from an IMAP source server, Microsoft Exchange Server 2007 users see reminders for calendar items. After the migration is complete, you can dismiss all reminders.
  
  
• The migration tool cannot migrate calendar items to a non-Calendar folder. Before you start the migration, you must make sure that all calendar items are moved to a Calendar folder.
