Again, MS has done a very poor job with Teams. No one thinks over there at MS and everyone seems to develop everything Half A$$
Using Skype for business All contacts including other Skype contacts that are not Skype for business are able to be communicated with.
Teams sucks, as it is a Silo and does not allow chatting with any other Skype users except for business.
It is extremely buggy when moving to teams only as no contacts or favorites are carried over and you are forcing everyone to re-setup everything all over again.
You loose all call logs and recent activity from Skype for Business so this is a huge headache and will not be deployed to any of my clients as this software simply sucks the way it is.
