Looking to run the MRM retention policy for a E3 mailbox and or Tenant. I have an old PST file (2011 and older) that I have attached to their active Office365 mailbox Inbox Subfolder and have a policy in MRM to send the online Archive. I know the MRM policy works because it has placed items in the "Online Archive" for the inbox and it's sub folders.
The questions is how often does this MRM policy run on it's own? Daily, hourly, weekly.
How do I force the policy to take effect immediately?
This is what I believe will do this via powershell:
Set-executionpolicy remotesigned -force
Set-executionpolicy unrestricted -force
$LiveCred = Get-Credential
Connect-msolservice -credential $LiveCred
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUrlhttps://ps.outlook.com/powershell/ -Credential $LiveCred -Authentication Basic -AllowRedirection Import-PSSession $Session
Set-Mailbox “mailbox name” -RetentionPolicy “Archive Policy”
Start-ManagedFolderAssistant -Identity “mailbox name”
