Block Outlook Anywhere for External Users on Exchange 2013

Satarbek S 21 Reputation points

Greetings all.

I need to block Outlook Anywhere on non-domain laptops of company employees. There are a lot of discussions on this topic here, but they don't work for me. As I need to block access on non-domain laptops, but leave it for mobile phones. If this is possible, can anyone share ideas.

At this time I have tried removing the external address, I have set MAPIBlockOutlookExternalConnectivity - $true, I have set MAPIBlockOutlookRpcHttp - $true.

    There is no really good way to do this other than blocking 443 externally for all and then requiring VPN for Outlook and mobile devices.
