    I may have missed it however, I'm pretty sure it's not covered in the videos. Office 365 tenant needs to be prepped for access from Bittitan to impersonate an office 365 admin account and to update max send/receive size limits. Maybe a small KB and an edit to the video.


    Set-ExecutionPolicy Unrestricted
    $UserCredential = Get-Credential
    $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $UserCredential -Authentication Basic -AllowRedirection
    Import-PSSession $Session
    New-ManagementRoleAssignment -Role "ApplicationImpersonation" -User
    # This determines what your current settings are.
    Get-Mailbox migrationwiz | fl mailboxplan,maxsendsize,maxreceivesize
    # This sets the Mailbox Plan, the max send size, and the max receive size for new mailboxes going forward.
    Get-MailboxPlan | Set-MailboxPlan -MaxSendSize 150MB -MaxReceiveSize 150MB
    # This sets the max send size, and the max receive size for existing gmailboxes.
    Get-Mailbox | Set-Mailbox -MaxReceiveSize 150MB -MaxSendSize 150MB
    Remove-PSSession $Session
