Expected behavior when mailboxes are migrated to Microsoft Office 365 using a migration method that doesn't maintain message creation time.

CollapseOverview

When a device is activated on BlackBerry Business Cloud service against an account that was migrated using any migration method that doesn't maintain the DateTimeCreated value, pre-populated messages show as being delivered at or shortly after the migration time.

BlackBerry Business Cloud service uses the DateTimeCreated value in the message object as the delivered time for the message and therefore the time should line up with when the item was created in the mailbox.

The most common cause for this is using the IMAP migration method that Microsoft provides.
This method connects to the Exchange mailbox using the IMAP messaging protocol and copies the message data to an already created mailbox in Microsoft Office 365. All messages moved using this method will effectively have a DateTimeCreated time that matches up with the migration time or more specifically when that particular message was created in Microsoft Office 365.

Note: This is by design.

Note: This will only affect existing messages after an activation post migration. It has no impact on Microsoft Office Web Access or Microsoft Outlook. All messages newly delivered to the mailbox will have the correct DateTimeCreated value.
