Control External Access in SFB Online

Vineet Arora


We want to have customized controls with external access.


For e.g. users should be able to communicate outside the organization, however, screen sharing will not be allowed.


Is this possible with SFB online?


I did look at customer policies but couldn't get hold of any such settings yet.


Many thanks in advance.

You can block external file transfer via the External communication policies (use Set-CSExtenralUserCommunicationPolicy to create a custom one:


While you can block desktop sharing, you cannot block it for just sharing with external users. If you need this functionality, vote on UserVoice:


Not that there are big chances for this to happen now that we have Teams :)

Thank you Vasil!
