When you use the Migration Wizard to migrate all users from cc:Mail to Microsoft Exchange Server, the cc:Mail mailboxes remain in the cc:Mail post office. When a cc:Mail user sends a message to a user whose mailbox has been migrated, the message goes to the cc:Mail mailbox instead of to the mailbox on Exchange Server.
This behavior is by design.
The Migration Wizard does not remove mailboxes and their contents from the cc:Mail system but copies them to Exchange Server and creates a mailbox for the migrated recipient. When the migration is complete, custom recipients that are associated with the cc:Mail mailbox for the same user are deleted. The new Exchange mailbox now has two cc:Mail addresses:
- The primary address, displayed in bold formatting, is the user's Exchange Server address in cc:Mail format.
- The secondary address is the user's old cc:Mail address.
This allows mail addressed to the user from an outdated personal address book to be successfully delivered.
To allow for recovery in case of a migration failure, the cc:Mail address for the user is not deleted from the mail directory. No changes are made to the cc:Mail data, and the old mailbox is not deleted from the cc:Mail post office.
After you confirm that the mailboxes are migrated successfully, manually remove or delete the user from the cc:Mail post office. During the next directory synchronization cycle, dirsync reports that a new Exchange user is created. Then Import.exe creates an entry for the migrated user in the cc:Mail directory, and mail is now delivered to the new Exchange Server mailbox.
