Archive mailbox issues for a mailbox that's migrated to or from Office 365

PROBLEM


When you migrate a mailbox to or from Microsoft Office 365 and use an archive mailbox, you experience an issue in which the Microsoft Exchange Mailbox Replication service (MRS) in Microsoft Exchange Online stamps the target domain value of the ArchiveDomain property of the mailbox at the end of the migration.

Note The issue shouldn't occur on an account that doesn't have an archive mailbox.

There are five scenarios that are related to archive mailboxes. Each scenario requires a different resolution.
  • Scenario 1 - Onboarding: You move your on-premises Microsoft Exchange Server mailboxes to Exchange Online.
  • Scenario 2 - Onboarding: Your archive mailbox exists in Exchange Online, and you move your primary mailbox from your on-premises Exchange Server environment to Exchange Online.
  • Scenario 3 - Offboarding: You enable an archive mailbox and then migrate both your primary and archive mailboxes from Exchange Online to your on-premises Exchange Server environment. A similar scenario occurs when your primary mailbox is already on-premises and you decide to offboard your archive mailbox from Exchange Online to your on-premises Exchange Server environment.
  • Scenario 4 - Offboarding: Your primary mailbox does not have an archive mailbox enabled, and you move your primary mailbox from Exchange Online to your on-premises Exchange Server environment.
  • Scenario 5 - Offboarding: Your primary mailbox exists in your on-premises Exchange Server environment, and your archive mailbox exists in Exchange Online. This scenario may occur when you take one of the following actions:
    • You offboard your primary mailbox. However, you leave your archive mailbox in Exchange Online.
    • Both primary and archive mailboxes are located in your on-premises Exchange Server environment. However, you onboard only your archive mailbox.
    Note The only supported archive split scenario is a primary mailbox on-premises and an archive mailbox in Exchange Online.

CAUSE


This issue occurs if a mailbox is migrated between an on-premises Exchange Server environment and Exchange Online.

If you use the following Windows PowerShell cmdlet to view the archive properties, you notice that the archive status is Active. However, much of the archive information is missing.

Get-Mailbox alias |fl Name, Archive* 
Note You can use either the on-premises Exchange Management Shell or Exchange Online PowerShell to run the cmdlet. For more info about how to use Exchange Online PowerShell, go to Connect Windows PowerShell to the Service.

When you run the cmdlet, the result resembles the following:
Name                : jsmith 
ArchiveDatabase :
ArchiveGuid : 00000000-0000-0000-0000-000000000000
ArchiveName : {}
