Error: 4024(errExchMapiFolderInvalid)
This can occur when the Folder Sync Service Account is missing the proper permissions on the mailbox in question.
To confirm a permission problem, attempt to open the mailbox using the Service account. If this fails, then the Service account is lacking the proper permissions.
The following two commands are required to correct this:
Get-MailboxDatabase | Add-ADPermission -AccessRights GenericRead -User "Service Account"
Get-MailboxDatabase | Add-ADPermission -AccessRights ExtendedRight -User "Service Account"
When viewing the Archive Details in the Arctera Management Console, the error below will be shown for Folder Sync.
