I was under the impression it would be possible to receive / send messages to Skype users via Teams chat functionality. After logging into my personal email account and attempting to message my Office365 address, no notification / message was received in Teams.

 

How do I go about configuring this to work?

I'm having the same issue.

Are these new threads, or did the thread start at some  point earlier perhaps when you were in Islands mode ?

For some, it definitively began in Island mode, but there are others users I never contacted before, and it does not seem to work either.

We used to be on Islands mode, and some of the users were set as TeamsOnly. We then saw that the users the were utilizing Sfb were not receiving messages, sent from TeamsOnly users, in their SfB clients. So then we disabled the Microsoft Teams license for the Sfb users and changed the configuration of the users to SfbOnly and TeamsOnly, but apparently this was not able to solve the problem. Everytime a TeamsOnly user searches for a SfbOnly user on the Teams client in order to start a new chat, he only find a Teams chat from that user and the message is unable to be routed to their SfB client. But the SfBOnly user can successfully send messages to TeamsOnly users.

I would suggest opening a support ticket then, the only known limitation I know is on old conversations that continue to follow the previous route, not new conversations.

Islands is the plague, but it should still be recoverable from this after changing after the fact but it doesn't seem to be the case these days. How long ago did you make the org change to S4bonly? Have you tried setting it to a specific user and also, try using the web client instead of desktop as that cache can stick around for 30 days.

Hi Chris, Valuable info here, I am still learning my way with office365 and its apps. I would say I changed it more than 30 days ago, and yes I set the users also, but I will definitively test it with the web client. Is there a way to clean that cache you talked about?
Highlighted
Thanks for your answer Steven, I will try Chris suggestions and if not successful, I guess I will have to open a ticket.

Def. need some tickets going, because I think that this interop is just broken if you start out in islands for any amount of time then switch. Which is unfortunate.

As for clearing desktop cache, usually signing out and back in is enough, but there are ways to completely clear it via file system, but try via web as last ditch effort, then go from there.

Ok thanks for your help, I appreciate. Being alone in IT for my company, sometimes it makes me pull my hair trying to follow the rates of changes in Microsoft products lately !

We also have the same issue.  my users who are using the Teams client and users who are using the S4B client can't see each other presence or even chat with each other.  I thought "Island" mode was supposed to allow this for migration purposes?  Communication between the two clients while everyone get migrated to the Teams client?

Highlighted
Na, islands is more like it sounds like! Separate ! Teams - teams and Skype - Skype! When you start mixing it’s a mess! Set people to Skype only and teams only instead

So how cant I get my employees to be able to chat/call and screen share with each other during the migration?

I hand this over to @Chris Webb who got much more experience regarding this matter

I'm still working on a fix, but I think this has something to do with the policies applied to the user via PowerShell. If somehow I'm able to figure this out, I'll definitely update this thread. I will have to troubleshoot my client's environment this afternoon so we'll see from there.

From my testing you can't go from Teams to Skype, but you can initiate Skype to Teams conversations, then Teams users can use those recent chats to talk. The issue is if a user types someone in on Teams and they only use Skype, it will go into a black hole. I still haven't had a chance to find a way around this yet. If I get some time later I'll let you know if I figure it out but you can start with these video's when it comes to migration.

The issue is, it doesn't exactly work as it's supposed to :).
On my side, I set all users to S4b for those who are only using Skype. Those who are using both Skype and teams are set to Island mode and for myself Team only. I though it wasn't working properly at first, but after posting here, someone suggested that we could not use in teams a chat already started with Skype. That was it for me. Did not realised that I had to start new conversations. Add to that that I was also trying to reach a user I have never chatted with before, and it wasn't working neither. So I was sure there was an issue. But the thing is, that user was saying "No didn't get your message" but her skype wasn't even connected to her account ! Doh ! Now I can say that it is working, from Team I can reach a s4b user and vice versa. But if you are in Island mode, s4b will go to s4b and teams to teams.

So which mode do I need to switch it to, if I'm on Teams and want send messages to S4B users and vica versa?  Also can I switch back to Island mode if needed?

Highlighted
If I get it correctly, it should work better if you set the teams users to teams only and the Skype users to Skype only!

Yes, you can revert back to islands if desired afterwards!
