Globally add Safe Senders to Outlook when using Office 365 Exchange Server

Hi,

We subscribe to Office 365 with Exchange Server at microsoftonline.com and I'd like to be able to globally add or remove individual email addresses (and entire domains) on all office copies of Outlook 2013 in our Office (about 28 copies) Safe and Blocked Senders list. The entire office is on a domain.

The server was initially setup by a third party who is no longer available to help so I'm stumbling around a little trying to figure out how things can be manipulated and done.

Our local server is Windows Server 2012 R2 being used as a Remote Desktop (Terminal) server. AD appears to synchronized with our Office 365 Business Account at Microsoft Online.

I found one way to achieve what we need to achieve by going online to the "Office 365 admin center > Admin > Exchange > Spam Filter" and editing the "Sender block list", "Domain block list", "Sender allow list" and "Domain allow list" however I'd like to be able to make global changes using our Server.

Looking around in the Local Group Policy Editor (gpedit.msc) on our Server, under "User Configuration > Administrative Templates" I can see where options exist to edit Microsoft Access 2013, Excel, InfoPath, Lync, Office, OneNote, Outlook, Powerpoint, Project, Publisher, SharePoint Designer, Visio and Word 2013.  I can see where I can set policies or defaults for many of the options, but I can't see anywhere that allows adding email addresses or domains to the Safe Senders list, or the Blocked Senders list.

Is the option to be able to do that locally via our server available that I'm not seeing or am I looking for something that doesn't exist, thereby the only way to achieve the result I'm looking for is only the online method that I found?

I hope the above makes sense.

I'm quite new to Office 365 Exchange online as well as to Terminal Server so any tips / pointers on the best way to achieve what I'm trying to do (or perhaps some links to tutorials) would be much appreciated.

Many thanks..
