How to transfer a domain from FOPE ( Forcefront/Frontbridge ) to Microsoft 365 / BPOS

Recently when setting up a domain which was already being filtered and hosted by Microsoft forefront into Office 365, Upon changing the nameservers, the MX records correctly updated from mail.global.frontbridge.com to 365's one (domain.outlook.com) , however the email still flowed to the host setup up in Frontbridge instead of the 365 Mailbox.

The local UK support number for Office 365 : 02034506455 did not pick up after 2 x 30minute sessions with holding music!

Next I tried Frontbridge International Support : 0018662917726 ( Which is free to call via Skype from anywhere ! ). Luckily a helpful techican ‘Mudassir Ansari’ helped me with the following :

You can fix this issue by performing the following ( pretty sure this will work to BPOS as well as 365) :

Make sure your domain is verified in Office 365 and the correct DNS is set or nameservers migrated

Download and install the Migration Tools 32bit here :

Go into your frontbridge control panel and disable the domain , then delete it!

Open a Power Shell Window

Enter this command : $LiveCred = Get-Credential

Enter your office 365 administrator Details

Enter this command : $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $LiveCred -Authentication Basic -AllowRedirection

Then this command : Import-PSSession $Session

Then this command : Set-AcceptedDomain **ENTER YOUR DOMAIN HERE** -OutboundOnly 

$true

Wait 2-3 Minutes

Then this command : Set-AcceptedDomain **ENTER YOUR DOMAIN HERE** -OutboundOnly $false

Then wait for Microsofts Cloud SMTP Servers to Update , in my instance it took 15 minutes.
