It looks like some people in the thread below have figured it out — we actually have this. You can start a chat both ways; the system will automatically recognize if this person is on Skype for Business or on Teams.
Thanks and let me know if you have any questions.
Update: After checking my Teams this morning I noticed that a lot of my contacts are now shown with a skype icon next to them.
But still some of them not. But I found a fix for that!
First you need to shutdown Teams, after that you need to delete the files from these folders ->
Now the whole cache is "cleared" and after starting Teams, I can send now everyone a message from Teams to Skype
Maybe I found a fix for this situation.
I'm trying to set up a Teams test group in our company and ran into the same issue.
I use the upgrade policy "Only Teams" and the rest of the company used islands before and now they're on "Skype for Business Only".
I can receive messages from Skype and users can see my online status but I cannot initiate a chat with them.
Until now! What I did, via PowerShell in this case, is the following:
I upgraded every user from "Skype for Business Only" as the upgrade policy to "Skype for Business with Teams collaboration"
The command for the powershell is:
Grant-CsTeamsUpgradePolicy -PolicyName SfBWithTeamsCollabWithNotify -Identity E-MAIL
It's been an hour now and though not every user appears with a skype icon in my contact list after searching them, a big bunch of users will get a message if I send them one.
For sure, it can be a solution but could also be another dead end but maybe this will help until we get an official word from Microsoft.
So if you want to give it a try, make sure to use the Power Shell because it looks like that those commands go through without trouble (instead of the chaos in the web admin center)
Hope this will help at least some of you, I will give it now time until Monday to shoot every one in the company some test messages :D
Hey, hop into this thread -> https://microsoftteams.uservoice.com/forums/555103-public/suggestions/17765740-skype-chat-both-ways
I think I found a fix for this situation (it includes changing the island mode to Skype for Business with Teams collaboration)
