So now when I search for a user using SfB but not teams, I just see them offline in teams, I get no option to IM them from teams and have it go to the SfB client. When disabled, integration is completely disabled.
Right click on or hold down the 'control' key on your keyboard and click on the Skype icon. You can disable the Skype for Business integration (default is enabled) With your Skype app open, move your cursor to your Dock.
If you go into settings and notifications In a recent update to Teams Microsoft gave the option to disable this integration per user on a user-side, client settings. some users find having the dual toasts annoying/confusing. You can then pick this IM up either in teams or SFB. In the other direction, if you are signed into SfB and Teams, and someone IM’s you from SfB, you’ll get a toast for SfB and a toast for teams Now when you IM them from teams, it shows up in their SfB, but when they reply it goes back to the Teams chat. Which is showing their SfB presence and warning you this message will go to their SfB.
If you are in teams and you want to contact a user in your organisation who is not signed into Teams but is on SfB, you’ll see this: One of the default behaviours is that you can Instant Message between Teams and Skype for Business. We’re seeing quite a few people pick up on testing Microsoft Teams and Microsoft is continually making updates and improvements.
