However, whenever someone invites you to a group conversation from Skype for Business, you’ll get a notification in Teams. Group messages can’t be sent to people using Skype for Business. You'll see a Skype for Business icon next to the chat in your chat list.įor more info about TeamsUpgrade modes, see Coexistence with Skype for Business. Search for them in Teams, type your message, and then send it. If someone has been assigned a coexistence mode, they'll be able to receive messages you send them from within Teams. Everyone using Skype for Business is assigned a TeamsUpgrade mode, either by default or by their admin. I'm hoping someone with actual experience of this particular issue where PTA works for everything else other than Skype Online will respond.Coexistence and interoperability between Teams and Skype for Business are determined by TeamsUpgrade modes. I'm not really looking for some helpful soul sending me these links or similar and asking me to review them, I obviously have: So I'm mainly looking for advise on what to look for next time aroundĪnd obviously working fine for Outlook as mentioned. But I need to enable PTA ASAP as other projects are dependent on it. Obviously I can't really have Skype out of commission so I had to revert to ADFS and everything is working fine atm. The Exchange OAuth2ClientProfileEnabled is set to True. Tested with Skype click-to-run and with the MSI version, both 2016 of course.

This stopped the error messages,īut I was unable to authenticate and the Skype client would just keep prompting for credentials. Then I realized the CSoAuthConfiguration -ClientAdalAuthOverride was set to NoOverride so I changed it to Allowed. Initially when changing to PTA/seamless-sign-on Skype clients would just come up with a generic error message.

However I mainly couldn't get it working for Skype Online, also iPhone Mail app, but I didn't spend much time troubleshooting that.

I had it working for Outlook, Azure AD enterprise apps, iPhone Outlook app etc. We are in the process of migrating from ADFS authentication to PTA.
