I recently came across a setting to configure the default client (Skype4b or Teams) for a user. There were 2 drop downs, one for messages and one for calls. I set the default for my user to Microsoft Teams, and now want to change it back to Skype4b, but I've searched everywhere and can't find this option. Is it gone, or am I just overlooking it?
I thought that's where the setting was, but I can't find it anywhere. It looks like perhaps the admin portal has already been updated for the 'new' coexistence modes you pointed to, and the old settings removed.
I love the faster pace of change that comes with O365, but sometimes it does get a bit frustrating.
Interestingly, I do have the Coexistence mode setting, but only have options for Islands, Skype4b only, and Teams only. I don't see the 'Skype for Business with Teams Collaboration' or 'Skype for Business with Teams Collaboration and meetings' modes that are mentioned in the doc. I can definitely see where those might be useful though, to reduce confusion during transition periods.
