Unable to migrate Notes Archive to Office 365 Archive Mailbox without first logging in as the user to "'activate" the archive.
When O365 creates the archive it creates a 'stub' which is not actually implemented until the user logs on and activates the archive.
WORKAROUND
Establish a remote powershell connection and then test the mapi connection for the users with the following commands, this will activate the archive.
$cred = Get-Credential
$session = New-PSSession -Credential $cred -AllowRedirection -ConnectionUri https://ps.outlook.com/PowerShell -Authentication Basic -ConfigurationName Microsoft.Exchange
Import-PSSession $session
Test-MapiConnectivity -Identity <SMTPaddress of the user>
SMTP address example:
Test-MapiConnectivity -Identity Don@quest.com
STATUS
Waiting for fix in a future release of Notes Migrator for Exchange
