*About Force Exchange Online Archiving to start archiving email on Office 365*

When you enable Exchange Online Archiving for a user on Office 365, it can take 24 hours or more for the Managed Folder Assistant to start it’s first run and begin archiving email out of the primary mailbox.

*TroubleShooting*

IF you’re using the Exchange Online v2 PowerShell module, then this process is considerably simpler, and supports Modern Authentication.

Open powershell and run this:

Connect-ExchangeOnline

Start-ManagedFolderAssistant -Identity user@example.com

IF you have trouble running this command run these:

Install-Module PowershellGet -Force

Press "yes to all" then run this:

Install-Module -Name ExchangeOnlineManagement

IF you want this process to start immediately, connect to Office 365 with PowerShell and tell the Managed Folder Assistant to start running.

$UserCredential = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
Import-PSSession $Session

Start-ManagedFolderAssistant -Identity user@example.com

Then wait 5 minutes or so for it to begin running and check the progress via logging in to OWA and looking at either the contents of the In-Place Archive mailbox in the left-hand sidebar or via the Exchange Admin Centre > Mailboxes > Recipients > In-Place Archive > View details.
