Users with upgrade mode: "Skype for Business with Teams collaboration"
Are you sure about this: "in the process of polling the recipient the sender will see the chat should be delivered to the skype endpoint based on the recipient's upgrade mode (skype with teams collab)."
When looking for this page: Upgrade journey building blocks
That state: "Interoperability with users in Teams Only". So I read that as island users are unable to communicate with users in "Skype with Teams collab".
Petri-X "Teams Only" is an unfortunate name for the policy, but you can't assume a company who names their product "Teams" and includes a way to add multiple "Teams" inside their "Teams" product is actually bringing their best.
Now take the same assumption of cluelessness on the part of the product team and apply it to the documentation team.
Congratulations, now the documentation page is useless to you (it was already almost useless though because they're trying to scrum a product migration process).
as for how the "Interoperability with users in Teams Only" blurb should actually be interpreted, it's just a contrast to Islands mode where they don't want to use the word "interop" because the idea of islands mode is that all comms land on the native client relative to whichever service originated them.
I mean, they also put "No overlapping capabilities" on the "skype with (whatever)" policies but left it off "SFB only" and "Teams only" sections. does that mean uses in SFB/Teams only modes have overlapping capabilities? no. they don't. it's just nobody complained about it yet and Microsoft is in this weird mode where they think they can run a business by waiting on people to complain about poor quality before they fix it.
