Symptoms

When you run a cmdlet in Exchange Management Shell to apply a retention policy that moves email messages from a user’s mailbox to the user’s archive mailbox in a Microsoft Exchange Server 2013 environment, the retention policy does not work. For example, you create a retention policy by running one of the following cmdlets:

  • New-RetentionPolicyTag "ArchiveTag" -Type All -RetentionEnabled $true -AgeLimitForRetention 90 -RetentionAction MoveToArchive

  • New-RetentionPolicy PolicyName -RetentionPolicyTagLinks "ArchiveTag"

  • Set-Mailbox Mailbox -RetentionPolicy PolicyName

  • Start-ManagedFolderAssistant -Identity Mailbox

Cause

This issue occurs because a System.InvalidCastException exception occurs when Managed Folder Assistant tries to process mailboxes.
