S4B On prem users cannot message or call Teams only users
Hi there, I am starting the migration of users from S4B on prem to Teams and i have noticed when i migrate a user to Teams only, their presence from a S4B user using the S4B client is unknown. Further the S4B user cannot call or message a Teams only user. Teams to Teams is fine. Configured S4B in hybrid mode. Default co existence is islands mode. Looked through this document and it should work https://docs.microsoft.com/en-us/microsoftteams/coexistence-chat-calls-presence Thoughts?
