Hey there - couple of quick questions from my team:

  • We are currently using Teams and Skype in Islands mode for our users, As we move down the path towards Teams, we need to allow users to initiate conversations from Teams to Skype users - How can we do this without forcing our users to use both clients?
  • In the mode above, presence is not appropriately reflected
  • Is the retention policy which is applied to teams inherited from either OneDrive or SharePoint?

Thanks in advance!

Gina,

 

- You can move the users to SfBWithTeamsCollab or SfBWithTeamsCollabPlusMeetings mode where chat and calling remains with Skype for Business. When moving users to TeamsOnly mode each user will have only one client they can chat and call with. In Islands mode you can't enforce single client use. 

 

- With the above method presence will align to the mode.

 

-  Settings retention policies in Teams. Please refer to this document. https://docs.microsoft.com/en-us/microsoftteams/retention-policies

 

Thanks

In addition to Laszlo's very accurate answer:

 

What you want is interop between SFB and Teams. It exists (for presence, P2P IM and P2P audio/video calls) when the users are in the so-called interop modes (SfBOnly, SfBWithTeamsCollab, SfBWithTeamsCollabAndMeetings, TeamsOnly). It does not exist (and cannot exist) in Islands mode. Kindly look at https://docs.microsoft.com/en-us/MicrosoftTeams/coexistence-chat-calls-presence

 

Users in Islands need to run and monitor both clients at all times. If they do, there is no issue. However if they don't, it will be a little bit as if someone had Facetime and another WhatsApp - they won't be able to communicate. That is significant when a user is upgraded to TeamsOnly, as at that point all of their communications to an Islands mode user will land on that user's Teams client. If it's not running or not monitored, the communication will not be received in a timely manner.

 

For that reason, Microsoft's guidance to customers in Islands mode is to not start upgrading users to TeamsOnly until they have reached adoption saturation, with all users running and monitoring both clients.

 

Customers who are uncomfortable with this approach can switch to one of the interop modes (we recommend starting with SfBWithTeamsCollab). In these modes chat and calls are only on SfB. When a user is upgraded to TeamsOnly, they will be able to interop with a user in one of the SfB* interop modes.

 

Note that we recommend making that change only for users who are not active in Teams. Users who are already active in Teams don't have that issue and should continue to have chat and calling in Teams. Only users who are not active should be changed. We have an on-demand documentation for that, feel free to contact me for it.

 

 

We have all our users in Islands mode.  A small amount of users are using the Skype and Teams client.  Is there a scenario where I can only use Teams as my chat client and still see presence from Skype only users (and they can see my Teams presence)?  I think this is explained in the link you provided but it gets complex rather quickly.

Hello Joe,

Indeed it is documented, here is the short version.

 

In Islands, each system works essentially in isolation. Each has its own presence and can communicate within its own island, SFB with SFB and Teams with Teams. There is no interop, i.e. no cross presence and no cross communication in Islands (no bridge between the islands if you will).

Islands works well if and only if everybody in the organization actively runs and monitors both clients. If (as is your case) only some users run and monitor Teams, or if some users stop running and monitoring SFB, it creates asymmetrical communication and can lead to inability to communicate at all.

 

If you need interop, you have to change away from Islands. Teams users need to be upgraded to TeamsOnly and SFB users need to be in one of the SFB* modes (SfBOnly, SfBWithTeamsCollab, SfBWithTeamsCollabAndMeetings). In the SFB* modes, chat and calling is off in Teams and on in SFB. In TeamsOnly, it's the reverse. In that configuration, presence will be visible from one to the other and chat and calling between TeamsOnly and SFB* users will go through as interop chat.

 

@Francois Doremieux, thanks for taking time to write such a detailed post! 
I had the exact same question and you answered it perfectly.
