Microsoft Teams User Tip #19: Teams SnapChat Feature: Skype for Business IM’s Disappear After a Period of Time

It appears like Skype for Business instant messages entirely disappear after a certain amount of time. (appears like 24hrs to me, but thats a rough estimate)

Take a looks in Chats after 24hrs, and presto, Gone!

So, just be aware, if you use Teams to Skype for Business IM Chats, they will not be saved or searchable in Teams. (Teams makes this clear). Also, they entirely disappear like a SnapChat photo!
