Hi,

I have an on-premises Skype for Business 2015 IM and presence deployment with external access and federation working fine in every regard except one;

For some reason my on premises users do not see any collaboration options (buttons) in their conversation windows for any Skype online / 365 homed users - hence they are not able to share desktops, programs, whiteboards, polls etc. It works fine the other way around, those 365 users can share anything with my on premises users. My on premises users are able to share amongst themselves, as well as any other federated partner who is also using an on premises platform.

All I see is 'Add Attachments' and 'My Notes' (as below)

Can anyone advise why this one way problem with 365 might exist?  There don't appear to be any conferencing or sharing related policies which differentiate between on-prem and 365, and the ports are the same as far as I can see. Everything is up to date in terms of versions and patching, and the problem exists on all machines with all users.

Thanks.
